Customer Reviews (4.8 / 5 · 5 reviews)

Natalie O. ★★★★★

These fit perfectly on my compressor's 3-inch cylinder. The 70 durometer feels just right for the application, and the price for 150 was better than the hardware store.

Samuel N. ★★★★★

Wanted spares for a hydraulic cylinder rebuild, and these arrived perfectly sized with the 2.975" inner diameter fitting snugly. The 70 durometer rubber compressed just right without feeling too hard, and the package of 150 will last me a long time.

Joshua ★★★★★

The 70 durometer feel is exactly what I needed for a tight seal on my hydraulic manifold. These fit snugly and the black color blends right in with the rest of the assembly.
