Customer Reviews (4.6 / 5 · 5 reviews)

Chloe ★★★★★

These o-rings fit perfectly on my hot water recirculation pump flange; the 9.234" inner diameter was spot-on for the groove. Silicone feels pliable yet firm, and I appreciate the -80°F to +450°F range for peace of mind with steam. Exactly what I needed for a reliable seal.

Ryan ★★★★★

I needed a custom-sized seal for a hot water filtration setup, and these O-rings fit perfectly with their 9.234" inner diameter and 0.139" cross-section. The red silicone feels durable and FDA compliant, giving me confidence for food-grade use. So far, they’ve held up without any leaks.

Harper ★★★★★

These rings handled the heat from my autoclave cycles without any softening or distortion, which was my main worry. The red color also makes them easy to spot during assembly.
