حلقات O من EPDM | AS568-150 | داش 150 | صلابة 70 | أسود (65/عبوة)

I was surprised how well these held up under continuous hot water exposure in my pressure washer. The EPDM material kept its shape perfectly even at nearly 200°F.

Installed these on my RV's hot water heater bypass valves last weekend and they sealed perfectly on the first try, no leaks. The -65°F to +300°F temperature range gives me confidence for both winterizing and summer road trips.

The 70 durometer feels nicely firm, and the 65-pack means I’ve got spares for days. These EPDM rings handled my hot water line without any swelling, which is exactly what I needed for that -65°F to +300°F range.
