Owen ★★★★★

The square profile on these seals really grips the gland better than round o-rings. I used them in a steam valve that sees 350°F and they haven't deformed at all.

Thomas N. ★★★★★

I’ve been using these in a high-heat manifold and the 70 durometer square profile holds up way better than my old round cross-section ones. They seal tight even after a few thermal cycles from cold start to operating temp.

Riley D. ★★★★★

The square profile on these AS568-118 Viton o-rings seals much better in my hydraulic fittings than round ones ever did. They handled the 300°F steam exposure without any deformation or hardening.
