حلقات EPDM دائرية | AS568-167 | داش 167 | صلابة 70 | أسود (22 / عبوة)

Finally, an o-ring that doesn't harden up in my cold workshop—these EPDM ones stayed supple even when I was working near freezing.

I’ve been through a few batches of these 167 o-rings for hydraulic repairs, and the 70 durometer feels just right—firm enough to seal well without being brittle. These EPDM ones arrived clean and measure exactly to spec, so no surprises during installation.

Measured these against a worn-out 167 I had and they matched perfectly — the 70 durometer feels solid without being too stiff. Worked great for sealing a coolant line on my equipment, and no leaks at all after a few heat cycles.
