Siliconen O-ringen | AS568-404 | Dash 404 | FDA-conform | 70 Shore | Rood (13 / Verpakking)

Finally got my old pneumatic actuator working again after swapping in these red o-rings; the -80°F to +450°F range gives me peace of mind for our outdoor equipment. They’re noticeably stiffer than the standard black ones I tried before, and the pack of 13 was exactly what I needed for this job.

Used these to replace the old seals on my pressure cooker and the 70 durometer silicone holds up perfectly under high heat. The bright red color also makes them easy to spot if one ever falls into the sink.

Finally an o-ring set that actually fits my application perfectly. The 70 durometer feels just right for the moderate pressure seal I needed, and the red color makes them easy to spot during maintenance checks.
