0.21" CS × 1.099" ID حلقات O-Ring من EPDM | AS568-320 | داش 320 | صلابة 70 | أسود (110 / عبوة)

I've been using these for a while now in a high-temp application, and they hold up perfectly at 300°F without any cracking or hardening. The 1.099" ID seals tightly on my hydraulic fittings with no leaks.

Used these to replace the worn-out seals on a hot water manifold, and the -65°F to +300°F range gives me peace of mind for the summer heat. The 70 durometer feels firm but not brittle when stretching them over the fittings, and all 110 in the pack were uniform.

The 1.099" inner diameter was exactly what I needed for my hydraulic fitting, and the 70 durometer feels durable. The -65°F to 300°F range gives me confidence it'll hold up in my hot water system.
