1-1/4 Inch Acme Propane Washer - 100 Pack

Keep Your Propane Equipment Leak-Free

Leaking propane connections are not just a nuisance; they are a serious safety hazard and a drain on your fuel budget. The Western Enterprises W-4 Washer is your first line of defense against leaks at the connection point. Designed specifically for 1-1/4" Acme threads—the big, coarse threads you see on forklift tanks and bulk fill lines—these washers are an absolute must-have for any shop that relies on propane power. When you are swapping out tanks or hooking up transfer lines, that little washer is the only thing standing between a secure system and a dangerous gas cloud.

Why choose the W-4? It is made from durable nylon that stands up to the harsh nature of LPG. Rubber seals can dry out, crack, or get chewed up by the threads, but these nylon washers are built to take the abuse of daily industrial use. They provide a solid, positive seal that you can feel when you tighten down the fitting. Because they are rigid enough to hold their shape but soft enough to seal, they compensate for the wear and tear that brass fittings naturally accumulate over time. If you hear a hiss or smell gas, nine times out of ten, it’s a bad washer. Having a fresh W-4 on hand solves the problem instantly.

We know that in a busy shop, small parts have a habit of disappearing or wearing out at the worst possible time. That is why we offer the W-4 in a convenient 100-pack bag. You never want to be the guy holding up the shift because a ten-cent washer is missing. With this bulk pack, you can stock them in the tool crib, keep a handful in the glove box of the delivery truck, and leave a few at the filling station. It is the smartest, cheapest insurance policy you can buy for your propane operations.

Don't compromise on safety with makeshift seals or worn-out parts. The Western Enterprises W-4 is the industry standard for a reason. It fits right, seals tight, and lasts. Whether you are running a fleet of forklifts, managing a campground filling station, or handling industrial heating gases, make sure your connections are secure with genuine Western Enterprises replacement washers.
