Husqvarna 584248702 Lawn Mower Fuel Tank Cap Genuine Original Equipment Manufacturer (OEM) Part

What It Is

This is a genuine OEM replacement fuel tank cap for Husqvarna walk-behind mowers and zero-turn riders. It seals the fuel tank to prevent leaks and debris ingress while allowing pressure equalization.

Fitment & Compatibility

Before buying, check your mower’s model number (usually on a sticker under the seat or on the frame). This cap fits many Husqvarna models with a standard 1.5-inch (38mm) threaded fuel neck, but not all—verify the thread pitch and cap diameter match your tank. It is NOT a universal cap; avoid aftermarket “fits all” alternatives if you want a guaranteed seal. Cross-reference with your owner’s manual or Husqvarna’s online parts diagram. Common compatible series include the LC, LT, and ZT lines from the 2010s onward, but always confirm.

Key Things to Know

• No tools required: Hand-tighten only—over-tightening can crack the plastic neck or damage the gasket.
• Genuine vs. aftermarket: OEM cap costs more ($22.55) but uses a specific rubber gasket and vent design that resists ethanol fuel swelling. Cheaper caps often leak or degrade within a season.
• Vent check: If your mower stalls or runs rough, the cap vent may be clogged. This cap has a built-in vent; clean it annually with compressed air or replace if issues persist.
• Common gotcha: The cap is not interchangeable with Husqvarna’s older “push-and-turn” style (pre-2008). Measure your current cap’s outer diameter and thread count to avoid mismatch.

Should You Buy It

If you need a leak-free, long-lasting seal for a compatible Husqvarna mower and want to avoid fuel smell or engine performance issues, this OEM cap is a solid choice. It’s not for budget builds or non-Husqvarna tanks, but for exact-fit replacement, it’s the right part.
