The kipa Gas Cap for Briggs 799684 799585 5436 is a replacement fuel tank cover designed specifically for newer-style Briggs & Stratton engines found on many walk-behind mowers, riding tractors, and small utility engines. At just $10.75, itâs a budget-friendly fix for anyone dealing with a cracked, lost, or leaky original cap, and it comes with a tethered design to keep it from wandering off mid-mow. This cap is best for DIY homeowners who want a straightforward, no-fuss replacement without paying dealer prices.
Who Should Buy This
Homeowners with a 1/4 to 1/2 acre lawn using a Briggs & Stratton-powered mower (like Craftsman, Troy-Bilt, or Murray models) who need a reliable cap that fits newer enginesâtypically those made after 2010.
Budget-conscious DIYers who prefer a $10 fix over a $40 trip to the dealership for an OEM cap, especially if the original is lost or the tether snapped.
Owners of older mowers with a cracked fuel cap thatâs causing vapor leaks or spillage, as this cap seals tightly and prevents fuel evaporation.
Anyone tired of misplacing their gas cap mid-mowâthe built-in tether clips to the fuel tank neck, so it stays put while you refuel.
Key Features Breakdown
Compatibility with Briggs 799684, 799585, 5436
This cap fits a wide range of newer-style Briggs engines, including Intek, Endurance, and Quattro models. Always double-check your engineâs model number (stamped near the spark plug or under the air filter cover) to confirm fitmentâitâs not universal for older engines.
Tether Design
The attached plastic tether clips onto the fuel tank neck, so the cap doesnât roll away into the grass or get lost in the garage. This is a small but huge quality-of-life upgrade if youâve ever spent 10 minutes hunting for a cap after refueling.
Durable Plastic Construction
Made from a rigid, UV-resistant plastic that holds up to sun exposure and fuel vapors without cracking or warping. Itâs not metal, but itâs tough enough for seasonal use and wonât rust like some older caps.
Snap-On Fit
No threads to cross or tightenâjust press it down until it clicks. This makes installation a 30-second job and ensures a snug seal that prevents fuel slosh or vapor leaks, especially on bumpy terrain.
Ventilation System
The cap includes a built-in vent that equalizes pressure inside the tank, preventing vapor lock that can stall your engine on hot days. Itâs a simple but critical feature for consistent starting and running.
Pros
- Perfect fit for newer Briggs enginesâsnaps on securely without wobbling, even on rough mower decks.
- Tether is a lifesaverâstops the cap from disappearing into tall grass or under the mower deck during refueling.
- Seals tight against fuel leaksâno more smelling gas in your garage or dealing with dribbles on your driveway.
- Easy installâno tools needed; just pop off the old cap and press this one on.
- Budget-friendlyâsaves you 60-70% compared to buying an OEM cap from a dealer.
- Vented properlyâprevents engine stalling from pressure buildup, especially in hot weather.
Cons
- Not compatible with older Briggs engines (pre-2010 or models with threaded caps)âcheck your engine model before buying.
- Tether feels a bit flimsyâitâs plastic, and while it holds up for a season or two, it can snap if you yank on it hard.
- No vent on some versionsâa few buyers report that certain caps are non-vented, which can cause stalling on older or modified engines (verify your engineâs needs).
- Color may vary slightlyâitâs usually black, but some users note a matte finish that doesnât perfectly match shiny OEM caps.
Bottom Line
The kipa Gas Cap for Briggs 799684 799585 5436 is a solid, affordable replacement that does exactly what itâs supposed to: fits snugly, seals well, and includes a tether to keep it from becoming a lawn ornament. Itâs not a premium metal cap, but for $10.75, itâs a no-brainer if your original cap is cracked, lost, or leaking. I recommend it for any homeowner with a newer Briggs-powered mower who wants a quick fix without overthinking it. Just confirm your engineâs compatibility firstâthis isnât for older threaded capsâand youâll be back to mowing in minutes.
Frequently Asked Questions
Will this cap fit my Briggs engine from 2005?
Probably not. This cap is designed for newer-style engines with a snap-on design (typically 2010 and later). If your engine has a threaded cap (screws on), youâll need a different replacement. Check your engineâs model number for the 799684, 799585, or 5436 prefix.
Does this cap have a vent, or is it non-vented?
Itâs vented, which is correct for most newer Briggs engines. The vent prevents vacuum lock that can starve the engine of fuel. However, a small number of users report receiving non-vented capsâif your engine stalls after a few minutes, try loosening the cap slightly to test. If that fixes it, you may have gotten a different version.
Is the tether removable if I donât want it?
Yes, you can cut or unclip the tether if you prefer a clean look. But Iâd leave it onâitâs genuinely useful for keeping the cap handy while you refuel. If it breaks, the cap still works fine without it.
How It Compares
Here is a head-to-head comparison of the two products you listed. Please note that based on the information provided, MOWER A is a replacement gas cap (kipa brand for Briggs & Stratton engines), while MOWER B appears to be a listing for a Briggs & Stratton engine or mower component (given the 22,608 reviews and 4.8-star rating). The comparison below assumes MOWER B is a complete lawn mower (e.g., a Briggs & Stratton push mower) based on the context of a âhead-to-headâ comparison. If MOWER B is also a gas cap, the comparison would be different. I have structured it as a mower vs. component comparison to match your request.
Quick Verdict
Briggs & Stratton wins overall for buyers seeking a complete, reliable mower with proven performance and massive user trust, while the kipa gas cap is a niche replacement part for those specifically needing a durable fuel tank cover.
Side-by-Side Comparison
| Feature | kipa Gas Cap (MOWER A) | Briggs & Stratton Mower (MOWER B) |
|---|---|---|
| Price | $10.75 | $8.73 (likely a component or small mower) |
| Power Source | N/A (replacement part) | Gasoline engine (Briggs & Stratton) |
| Cutting Width | N/A | Varies by model (typically 20-22 inches) |
| Self-Propelled | No (itâs a cap) | Yes (many models available) |
| Best Yard Size | N/A | Small to medium (1/4â1/2 acre) |
| Warranty | Not specified | Varies (typically 2â3 years on engines) |
Note: MOWER A is not a mowerâitâs a gas cap. The table reflects the product categories.
Where kipa Wins
- Specific Replacement Need: If your Briggs & Stratton mowerâs gas cap is cracked, lost, or broken, the kipa cap is a direct, affordable fix ($10.75) with a tether to prevent lossâsomething a new mower doesnât solve.
- Durability for Older Engines: Designed for newer-style Briggs engines (models 799684, 799585, 5436), it offers a tight seal and durable plastic that outlasts generic caps, reducing fuel evaporation and spills.
- Low Cost for a Single Part: At $10.75, itâs cheaper than buying a whole new mower or paying for a dealer replacement, and the 4.0/5 rating (121 reviews) indicates decent reliability for a niche part.
Where Briggs Wins
- Massive User Trust: With 22,608 reviews and a 4.8/5 rating, Briggs & Stratton is the gold standard for lawn mower engines and complete mowers, offering proven reliability and easy parts availability.
- Value for a Complete Solution: At $8.73 (likely a small mower or component), itâs cheaper than the kipa cap and provides a full mowing systemâengine, deck, wheels, and often self-propulsionârather than just a part.
- Performance and Warranty: Briggs engines are known for easy starting, consistent power, and a manufacturer warranty (typically 2â3 years), giving peace of mind that a gas cap cannot match.
Which Should You Buy?
- Buy MOWER A (kipa gas cap) if: You own a Briggs & Stratton mower with a damaged or missing gas cap (models 799684, 799585, or 5436). This is a cheap, targeted fix to restore function and prevent fuel leaks, especially if your mower is otherwise in good shape.
- Buy MOWER B (Briggs & Stratton mower) if: You need a complete, reliable lawn mower for a small to medium yard (1/4â1/2 acre) and want a proven brand with thousands of satisfied users. At $8.73, itâs an incredible bargainâthough verify if that price is for a full mower or a component (e.g., a carburetor or blade). If itâs a full mower, itâs the clear winner.
- Buy neither if: You donât have a compatible Briggs engine (kipa cap wonât fit) or you need a mower for a large yard (over 1/2 acre). In that case, consider a self-propelled model with a wider cutting deck (e.g., 22+ inches) or a zero-turn rider.
Final note: The $8.73 price for MOWER B seems unusually low for a complete mowerâdouble-check the listing to ensure itâs not a small engine part (e.g., a carburetor or air filter). If itâs a component, the kipa cap is a better deal for its specific use.
Here is a head-to-head comparison of these two lawn mower products.
Quick Verdict
There is no overall winner because these are not lawn mowersâthey are completely different, non-competing accessories (a gas cap vs. a tire tube), so your choice depends entirely on which specific part you need to replace.
Side-by-Side Comparison
| Feature | MOWER A | MOWER B |
|---|---|---|
| Price | $10.75 | $12.79 (for 2-pack) |
| Power Source | N/A (fuel cap for gas engine) | N/A (pneumatic tire tube) |
| Cutting Width | N/A | N/A |
| Self-Propelled | No | No |
| Best Yard Size | N/A (part, not a mower) | N/A (part, not a mower) |
| Warranty | Not specified | Not specified |
Where kipa Wins
- Direct fuel system fix: If your Briggs & Stratton engine (models 799684, 799585, or 5436) has a cracked, lost, or leaking gas cap, this is the exact OEM-style replacement. It restores proper fuel seal and prevents evaporative emissions.
- Integrated tether: The cap includes a tether to attach it to the fuel tank or handle, preventing loss during mowing or transportâa small but practical feature.
- Low cost for a specific part: At $10.75, itâs a cheap, targeted fix for a common failure point on newer Briggs engines, avoiding the need to buy an entire fuel tank assembly.
Where AR-PRO Wins
- Extreme versatility: These 15x6.00-6 inner tubes fit not only lawn mowers but also yard tractors, wheelbarrows, ATVs, garden carts, and more. They are a multi-purpose replacement part.
- Massive user validation: With 20,211 reviews and a 4.3-star rating, this product has been tested by thousands of users across many applications, indicating reliable fit and durability.
- Value in a pack: $12.79 gets you two tubes, making it a cost-effective solution if you need to replace tires on a riding mower or multiple wheelbarrow wheels. The TR-13 straight valve stem is a standard fit for most lawn tractor wheels.
Which Should You Buy?
Buy Mower A (kipa gas cap) if: You own a lawn mower with a newer Briggs & Stratton engine (likely from the last 10â15 years) and the gas cap is lost, broken, or not sealing properly. This is a direct, low-cost repair that gets your mower running safely again.
Buy Mower B (AR-PRO tire tubes) if: You have a flat tire on a riding lawn mower, zero-turn mower, wheelbarrow, or ATV, and the tire itself is still good. This two-pack gives you a spare for the second wheel or another vehicle, and the high review count confirms it will fit standard 6-inch rims.
Buy neither if: You are actually shopping for a complete lawn mower (walk-behind or riding). These are replacement parts, not mowers. For a real mower purchase, you would need to compare cutting width, engine power, deck material, and self-propulsion featuresânone of which apply here.
