Customer Reviews (4.8 / 5 · 5 reviews)

Ruby ★★★★★

These seals fit perfectly into a hydraulic repair job where the originals were leaking. The 70 durometer is stiff but pliable enough to seat smoothly without cutting, and they’ve held up fine so far at 300°F.

Lucy K. ★★★★★

Used these in a high-temp manifold that's been cooking at 350°F for weeks now—the Viton cross-section hasn't deformed a hair. The 0.546" inner diameter fit snug without any wrestling, and the 60-count bag means I've got spares for the next rebuild.

Penelope P. ★★★★★

The 70 durometer held up perfectly when I torqued the fittings down, and the -15°F to +400°F range gives me peace of mind for hot oil lines. Came in a tidy 60-pack, so I've got spares for the next rebuild.
