حلقات O من النتريل بونا-N | AS568-166 | داش 166 | صلادة 70 | أسود (100 / عبوة)

The 70 durometer hardness feels just right—firm enough to seal snugly without being a pain to slip into place. I grabbed a pack for a few rebuilds and the -40°F to +250°F range gives me confidence for both cold lines and hot applications.

Fits perfectly on my hydraulic filter housing where the old ones had worn out. The 70 durometer feels just right—not too soft, not too stiff, and I like that they’re rated down to -40°F.

Put these on my pressure washer fittings and they sealed perfectly the first time — no leaks at all. The 70 durometer feels firm enough to hold up to the heat, and you get a solid hundred rings in the pack for the money.
