Isabella ★★★★★

Needed a reliable seal for a high-pressure pneumatic system and these Dash 310 o-rings fit perfectly. The 90 durometer material feels robust and the temperature range covers my needs. So far no leaks after several weeks of use.

Jacob Z. ★★★★★

The 0.474" inner diameter fits my pneumatic fittings perfectly, and the 90 durometer material seals tight without being too stiff. I've run these in a hot hydraulic line up to about 200°F with no leaks at all.

Jacob ★★★★★

These 90 durometer rings are noticeably stiffer than the standard ones I've used before, which is exactly what I needed for a high-pressure hydraulic application. The 0.474" inner diameter matched my fittings perfectly, and the pack of 500 will last me years.
