حلقات O من Viton FKM 0.21 بوصة CS × 1.85 بوصة ID | AS568-328 | داش 328 | صلابة 90 (30 / عبوة)

The 0.21" cross-section gives a nice, snug fit in the groove I needed. I grabbed these for a steam line repair and the 90 durometer feels robust, so I'm confident they'll hold up at the higher temperatures.

I use these for a high-temp seal on a steam valve, and the -15°F to +400°F range handles the cycling perfectly. The 0.21" cross-section feels solid, and the 90 durometer gives them a firm, durable grip.

The 90 durometer rating on these is perfect for keeping a tight seal in my steam application. They handle the 400°F max temp without getting brittle, and the pack of 30 means I’ve got spares for future maintenance.
