حلقات O-Ring EPDM 0.139 بوصة CS × 6.359 بوصة ID | AS568-261 | داش 261 | صلابة 70 | أسود (22 / عبوة)

The temperature range on these is what sold me, and they’ve held up fine in a hot water setup without any visible wear. The 70 durometer hardness feels just right for a snug seal, and the 6.359" ID was spot on for my housing.

These fit perfectly as a replacement for the gasket on my water filter housing. The 70 durometer feels solid but still flexible enough to seat properly without fighting it, and the -65°F to +300°F rating gives me confidence for year-round outdoor use.

Used a few of these EPDM o-rings to replace worn seals on an old water tank, and the 70 durometer feels nice and firm under pressure. They handled the hot water without any swelling or softening, just like the spec said they would.
