Aurora ★★★★★

The temperature rating of -40°F to +250°F gives me confidence these will hold up in my outdoor hydraulic equipment. The 55-pack is plenty for multiple repairs, and the price is a steal compared to buying individually.

Sebastian ★★★★★

The 70-durometer hardness is just right for my hydraulic fittings—firm enough to seal without being a pain to install. At 55 per pack, this is a solid value for anyone needing a bunch of standard dash 405 o-rings.

Lily X. ★★★★★

These fit perfectly on the Parker-style flange fittings I was working on last weekend. The 70 durometer feels firm enough for fuel applications, and the price for a pack of 55 was hard to beat.
