حلقات O من EPDM | CS 0.103 بوصة × ID 1.986 بوصة | AS568-136 | داش 136 | صلابة 70 | أسود (120 / عبوة)

Installed these on a few fittings in a steam line, and they’ve held up perfectly even at higher temps. The 70 durometer feel seems just right for a snug seal without being too stiff.

I needed a durable seal for a hot water recirculation pump, and these EPDM o-rings handle up to 300°F without any issue. The 70 durometer feels just right—firm enough to hold pressure but not brittle, and the whole bag of 120 was a solid value.

The 1.986" inner diameter fit my housing perfectly on the first try, no wrestling or stretching needed. These 70 durometer rings feel dense and solid, and the -65°F to +300°F range covers my steam exposure without a second thought.
