حلقات O من مطاط بونا-نايتريل | AS568-232 | داش 232 | صلابة 90 (200 / عبوة)

Was replacing old cracked seals on a hydraulic manifold and these 232s slid right into the grooves without any wrestling. The 90 durometer hardness is noticeably stiffer than the stock ones, which gives me confidence they'll hold up at 250°F.

These 90-durometer rings fit perfectly on my hydraulic cylinder, and the 200-count package gives me plenty of spares for future rebuilds. The material feels dense and durable, just what I needed for a high-pressure seal.

Used these as replacement hydraulic seals on a log splitter and they seated nicely without any extra coaxing. The 90 durometer feels firm enough for higher pressure applications, just wish they came in a smaller pack for occasional use.
