حلقات O-Ring HNBR 0.139 بوصة CS × 4.109 بوصة ID | AS568-243 | داش 243 | صلابة 90 (10 / عبوة)

The 90 durometer feel is noticeably firmer than the standard 70s I usually grab, which is exactly what I needed for this high-pressure line. They slipped into the groove cleanly and sealed up tight on the first try.

The 90 durometer is exactly what I needed for a high-pressure seal, and the 4.109" ID matched the groove perfectly on the first try. Service range covers everything I'll ever throw at it, including some cold winter starts.

These HNBR o-rings fit my hydraulic cylinder perfectly; the 90 durometer feels much sturdier than the standard ones I've been using. Installed them yesterday and they sealed immediately with no leaks.
