Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

The cross-section on these is exactly 0.21" as specified, and they fit perfectly on my hydraulic fitting. Viton holds up great under the heat cycling in my shop.

Ellie ★★★★★

Replaced the seals on my compressor manifold after the old ones hardened up, and these Viton x-rings slipped right into place. They handle the 350-degree exhaust heat without any issue so far, and the 70 durometer feel gives just the right amount of give under pressure.

Riley ★★★★★

Hadn't used FKM rings before but needed something that could handle higher heat in a hydraulic fitting; these slipped on easily and the x-ring profile sealed tighter than my old standard o-rings.
