Aurora ★★★★★

The fit was perfect for replacing worn seals on a coolant line, and the 800-count package will last me through several projects. The Buna-N material feels durable, and the price per ring is unbeatable.

Ellie ★★★★★

The 70 durometer is spot-on for my hydraulic fittings; they seat perfectly without being too stiff. I bought the 800-pack expecting to have leftovers for years, but already used half on a weekend project.

Sofia B. ★★★★★

Needed to restock my dash 209 o-rings and these are exactly to spec, the 70 durometer feels right for a general seal. The 800-count box is a solid deal for the price, and they slipped onto the fittings without any cracking.
