حلقات O-Ring من Viton FKM مقاس 0.103 بوصة CS × 2.049 بوصة ID | AS568-137 | داش 137 | صلابة 75 | أسود (50/عبوة)

The 75 durometer hardness feels just right for my fittings—firm enough to seat properly but not brittle. These Viton rings handle the 350°F heat cycles in my process line without any sign of degradation, and the 2.049" ID matched the groove perfectly on the first try.

I replaced the old seals in my pump with these and they seat perfectly in the groove. The Viton material handles the heat well, no issues so far after a week of use on a hot oil system.

Fit perfectly on my hydraulic fitting and the 75 durometer feels just right for the pressure. The only thing is the bag came with a few that looked slightly scuffed, but most are clean.
