Customer Reviews (4.2 / 5 · 5 reviews)

Joseph ★★★★★

I needed replacements for high-temp pneumatic seals, and these EPDM o-rings handle the -65°F to +300°F range perfectly. They fit snugly on the 4.1" ID port and haven't leaked since installation.

Avery ★★★★★

These fit the 4-inch bore on my water pump perfectly, the rubber feels dense and substantial. They seated easily in the groove and the seal is holding strong with no leaks after a week of heavy use.

Michael ★★★★☆

I needed a replacement for a worn-out seal on a hydraulic fitting, and these 4.1" ID rings fit perfectly. The 70 durometer feels like it'll hold up well against the ethylene glycol in my system.
