حلقات O من السيليكون 0.21 بوصة CS × 13.475 بوصة ID | AS568-380 | داش 380 | متوافق مع FDA | صلابة 70 | أحمر (8/عبوة)

These red o-rings handled the high-heat sterilization cycle in my commercial kitchen without any visible wear or hardening. The exact 13.475-inch inner diameter was a perfect fit for my large pressure vessel lid.

The 70 durometer hardness feels just right—pliable enough to seat easily but firm enough to hold a solid seal. I swapped out the old brittle ones on my brewing setup and these red FDA-compliant rings fit the groove perfectly, no leaks after a week of daily use.

The wide temperature range of -80°F to +450°F was exactly what I needed for a steam seal application, and the red color made them easy to spot during install. These 70 durometer rings fit snugly without being too stiff.
