Customer Reviews (4.6 / 5 · 5 reviews)

Matthew N. ★★★★★

The 90 durometer hardness is perfect for high-pressure applications, and these seals fit my hydraulic fittings exactly as expected. I used about a dozen so far and every one seated perfectly without any leaks.

Elizabeth ★★★★★

I needed a seal for a hydraulic cylinder that sees constant heat near 200°F, and the 90 durometer rating on these gives me confidence they'll hold up. The bag of 500 is more than enough for our shop, and the AS568-214 size was exactly what the old part called for.

Sebastian F. ★★★★★

These o-rings fit perfectly in my pneumatic cylinder rebuilds, and the 90 durometer feels noticeably more durable than the stock ones. For a 500-count box at this price, it's a solid deal.
