حلقات O-Ring من EPDM مقاس 0.139" CS × 3.609" ID | AS568-239 | داش 239 | صلابة 70 | أسود (55 / عبوة)

Finally found a dash 239 that actually fits my air compressor filter housing perfectly. The 70 durometer feels just right for the low-pressure seal I needed, and the whole pack of 55 was less than what a single specialty store wanted.

Had to replace an old gasket on my pool pump and these 3.609" o-rings were spot-on. The 70 durometer feels firm but pliable enough to seat easily, and they've handled the hot water cycles without any leaks.

The EPDM material held up perfectly after a week of constant hot water exposure at around 200°F, zero swelling or hardening. The 3.609" ID fit my housing snugly without any wrestling match, and the 70 durometer feels just flexible enough. These will definitely be my go-to for high-temp seals.
