Customer Reviews (4.8 / 5 · 5 reviews)

Sofia S. ★★★★★

The 3.239" inner diameter matched my pump housing perfectly, and the Viton handles the 350°F steam near my valve. Took a while to ship, but the heat resistance made it worth the wait.

Elizabeth T. ★★★★★

The 0.07" cross-section fits perfectly into a tight hydraulic groove where a Buna-N had failed before. They slide in easily and the Viton handles the 350°F steam cycles without any sign of hardening so far.

Carter ★★★★★

Had to swap out a standard Buna-N that kept swelling in hot oil, and these Viton rings slid right into the same groove without a fuss. The 70 durometer feels just firm enough, and the -15°F to +400°F range covers everything my pump sees. Twelve in the pack means I’ve got spares for the next rebuild.
