Joshua ★★★★★

Finally found a bulk pack of dash 224 o-rings that actually measure true to size, and the 70 durometer feels just right for my air compressor rebuilds. The -40°F to +250°F range gives me confidence they'll hold up in both cold shop winters and hot summer runs.

Matthew ★★★★★

These o-rings fit the hydraulic cylinder on my old press perfectly, and the 400-count pack means I have plenty for future repairs. The -40°F temp rating gives me confidence they'll hold up in my unheated shop this winter.

Zoe Y. ★★★★★

The 70-durometer hardness is just right for getting a snug seal on the hydraulic fitting I had leaking. With the high-temp range listed, I'm confident these will hold up in summer heat.
