Customer Reviews (4.2 / 5 · 5 reviews)

Natalie ★★★★★

These o-rings fit perfectly on a hot oil filter housing I rebuilt last week. The -15°F to +400°F rating gives me confidence they won't fail under extreme conditions.

Ryan ★★★★★

These hit the spot for a high-temp seal replacement I needed. The 75 durometer stiffness feels right for the application, and having 13 in the pack means I've got spares for the next job. They fit perfectly on the 3.359" bore I was working with.

Ellie ★★★★☆

Used a couple of these on a high-temp pneumatic actuator seal replacement. The 75 durometer feels a bit stiffer than I expected, but they seated well and held pressure. Only ding is I wish they came in a larger pack for the price.
