Customer Reviews (5.0 / 5 · 5 reviews)

Andrew Q. ★★★★★

I needed a precise fit for a high-temp hydraulic application and the 0.796" inner diameter on these HNBR rings was spot on. They feel denser than standard nitrile, which made installation snug without any struggle.

Ryan C. ★★★★★

The temperature range on these is what sold me—my setup sees 250°F regularly and the HNBR compound hasn't hardened or cracked after months of cycling. The 80 durometer feels firm but still seats easily into the groove. Exactly the right dimensions for my AS568-211 fitting.

Kevin ★★★★★

Been using these in a high-heat pneumatic application that reaches nearly 250°F and they've held up perfectly with no hardening or cracking. The 80 durometer gives just enough firmness for a reliable seal without being too stiff to install.
