Description
This small gasket may not look like much, but it does a big job. It fits right into Leybold Trivac pumps – the popular S4A, D2A, D4A, and their AC versions.
Inside these oil-sealed rotary vane pumps, gaskets stop air leaks and hold the vacuum. Without a good seal, your pump loses power and works harder than it should.
Many technicians use this exact part when they rebuild or service a pump. You’ll often see it listed twice in major repair kits because it goes in two places. It’s a direct match for the Leybold piece, so it drops in easily and lasts.
If your pump is older or you just want to be safe during maintenance, this gasket is a smart, low-cost fix.
