Customer Reviews (4.6 / 5 · 5 reviews)

Evelyn S. ★★★★★

I needed a bulk pack of small o-rings for a hydraulic manifold rebuild, and the 70 durometer on these feels identical to the originals. At 1500 per package, I've got plenty of spares for future repairs without worrying about sourcing again.

Steven ★★★★★

Finally got around to replacing all the worn o-rings on my hydraulic setup; the 70 durometer feels just right and they slid into the grooves easily. Having a full bag of 1500 means I won't run out mid-project, which is exactly what I needed.

Lucy ★★★★★

The dash 105 size fits perfectly where my old metric ones didn't, and the 70 durometer feels firm but still seats easily. Bought the 1500 pack so I'm set for years, especially with that 250°F rating holding up in hot oil.
