Amelia S. ★★★★★

The 70-durometer feel is just right for my hydraulic fittings – stiff enough to hold pressure but still easy to snap into place. Having 300 in one package means I'm set for several projects without reordering.

William ★★★★★

I needed a bulk batch for a pneumatic rebuild project, and these X-rings fit the dash 211 groove perfectly. The 70 durometer feels just right for the moderate pressure seals I'm making.

Ava ★★★★★

These seals fit perfectly on my hydraulic fittings and the 70 durometer feels like the right balance of flexibility and durability. The temperature range down to -40°F gives me confidence for my outdoor equipment.
