حلقات O من بونا-ن نيترايل 0.103" CS × 1.861" ID | AS568-134 | داش 134 | صلابة 70 | أسود (500/عبوة)

Installed a few of these in a pneumatic actuator that sees temps down to -20°F, and they seal perfectly without any hardening. The 70 durometer feels right for most static applications, and the whole bag arrived neatly packed.

Bought these for a hydraulic rebuild and the 70 durometer hardness feels exactly right—not too squishy, not rock hard. They seated in the grooves without any twisting or binding. The -40°F to +250°F range covers everything I'll throw at them.

The 0.103" cross-section on these AS568-134 rings is spot on for my hydraulic repair job, and the 70 durometer feels just right. I’ve installed about a dozen so far without any leaking or distortion, even at the higher end of their temp range. I’m glad I grabbed the 500-pack instead of a smaller lot
