حلقات O من السيليكون | AS568-908 | داش 908 | متوافق مع FDA | صلابة 70 | أحمر (300/عبوة)

Wanted these for a high-heat application near a kiln, and the -80°F to +450°F range is exactly what I needed. They seat nicely in the groove with that 70 durometer—firm but not too stiff. Good to have a pack of 300 for future projects, too.

I needed o-rings that could handle both high heat and cold, and this silicone set handles up to 450°F perfectly. The 70 durometer feels solid and the red color makes them easy to spot during installation.

The 300-count box gives you serious bang for your buck, and the red color makes them easy to spot during assembly. I’ve had no issues with sealing even when the setup ran hot, and the -80°F to +450°F range gives me real peace of mind for the tougher jobs.
