حلقات O-Ring من Viton FKM | AS568-170 | داش 170 | صلابة 75 | بني (12/عبوة)

I needed a reliable seal for a hot oil line, and these Viton o-rings fit the groove perfectly. The -15°F to +400°F range gives me confidence they'll hold up where Buna-N would have failed.

I needed a replacement for a fuel system o-ring that kept swelling with regular rubber, and these Viton ones fit perfectly and haven't softened at all after a month in the gas. The brown color also makes them easy to spot against the black fittings.

These held up perfectly on a hot engine bay that gets way past the 400°F limit they’re rated for, and the brown color made them easy to spot during the install. The 75 durometer feels firm but not brittle, and a dozen in the pack was just enough for my whole job.
