Customer Reviews (4.8 / 5 · 5 reviews)

Harper ★★★★★

I needed a good seal for a hydraulic cylinder rebuild, and these 70 durometer o-rings fit the dash 046 groove perfectly. The -40°F low temp rating gives me confidence they'll handle winter use without becoming brittle.

Avery ★★★★★

The dash 046 size was exactly right for my hydraulic fittings, and the 70 durometer feels firm without being brittle. I’ve got a box of 250, so I’ll be set for years. These handle the heat in my shop without any issues so far.

Robert N. ★★★★★

Finally got around to replacing some aging o-rings in a hydraulic cylinder, and these fit the 4.239" ID perfectly. The 70-durometer material feels less brittle than the old ones I took out.
