Hazel E. ★★★★★

I needed o-rings that could handle both high heat and cold temp swings for my hydraulic system, and these AS568-111s with their -40°F to +250°F range fit the bill perfectly. The 0.424" ID seated snugly without any leaks, and the 90 durometer material feels tough enough to last.

Ava V. ★★★★★

The 90 durometer hardness is perfect for my hydraulic fittings where I needed a firmer seal than standard o-rings. They fit precisely on the groove and I haven't had a single leak in the two weeks since installation.

Emily ★★★★★

The inner diameter measurement on these AS568-111 rings is spot on, making them a perfect fit for my hydraulic fittings. They held up great under constant oil exposure at around 200°F, so the nitrile material does exactly what it’s rated for.
