Customer Reviews (4.8 / 5 · 5 reviews)

Mia ★★★★★

The cross-section feels exactly right for the groove I measured, and the rubber stayed flexible when I installed them in a cold garage. No leaks so far on my test assembly, and the 70 durometer seems durable enough for the pressure range I'm using.

Lily ★★★★★

These o-rings fit perfectly on my hydraulic cylinder rebuild, the 70 durometer feels like quality rubber. The 6.484" inner diameter was dead on as measured with my calipers, and they sealed up tight on the first try with no leaks.

Kevin Z. ★★★★★

Fitting these was a breeze since the 70 durometer is just soft enough to seat without fighting, yet they hold their shape well. The temperature range covers everything I deal with, from cold winter lines to hot summer runs. Glad I bought the 70-pack instead of scrambling for singles later.
