حلقات O-Ring من EPDM | 0.21 بوصة CS × 15.975 بوصة ID | AS568-385 | داش 385 | صلابة 70 | أسود (6 / عبوة)

The 70 durometer hardness is spot on for my pump housing, and the -65°F rating gives me peace of mind for winter outdoor gear. These seated perfectly in the groove with zero binding, and the black color hides any grease stains nicely.

The 15.975" inner diameter fit my application perfectly after another seller's ring came up short, and the 70 durometer feels firm but flexible enough to seat properly. I've had them on for a few weeks now in a warm environment and they've held up without any signs of hardening.

Needed a large o-ring for a hydraulic press repair, and this one with the 15.975" inner diameter was a perfect fit. The 70 durometer feels firm enough to handle the pressure without being too stiff to seat properly.
