LC221A Gas Tank Fuel Cap For Husqvarna LC221A Lawn Mower 675EXi 725EXi

What It Is

This is a genuine OEM fuel cap for Husqvarna LC221A lawn mowers, designed to seal the gas tank on models equipped with the 675EXi or 725EXi engine. It’s a direct replacement part for the original cap that came with your mower.

Fitment & Compatibility

• Exact models: Husqvarna LC221A (all deck sizes use the same tank/cap). Engines: 675EXi, 725EXi.
• Check before buying: Confirm your mower model number (stamped under seat or on deck) and that the cap’s outer diameter matches your tank opening. Measure across the cap’s base—should be ~1.5 inches.
• OEM vs aftermarket: This is OEM Husqvarna (part likely 532 14 36-01 or similar). Aftermarket caps may cost less but often have looser fit or poor venting. Stick with OEM for gas seal reliability.
• Venting: The cap has a built-in vent; if your mower runs rough or stalls after fueling, a clogged vent is the issue. This cap replaces that.

Key Things to Know

• Quality concerns: Rating is 3.4/5 with only 7 reviews—some report the cap doesn’t seal as tightly as original, leading to fuel slosh or odor. Inspect the gasket before installation; it’s replaceable separately.
• Installation: Dead simple—twist off old cap, twist on new one. No tools needed. Takes 30 seconds.
• Common gotcha: If your old cap was cross-threaded or damaged, the tank threads may be worn. A new cap won’t fix that—check tank threads first.
• Vent check: After installing, run the mower for 5 minutes. If it still stalls, the vent in the new cap might be defective—test by loosening cap slightly while running.

Should You Buy It

Buy this if your LC221A’s original cap is cracked, missing, or won’t seal (gas smell or leaks). It’s a direct OEM fit for a straightforward swap. Skip it if you suspect tank thread damage—you’ll need a tank replacement instead. For the price, it’s a reliable fix for a common annoyance.
