James ★★★★★

I needed a silicone o-ring for a large-diameter industrial seal and these fit perfectly—the 20.975” inner diameter was spot on. The red color makes them easy to spot during assembly, too.

Adam X. ★★★★★

The high-temp rating was exactly what I needed for my smoker's door seal; these have held up perfectly through multiple burns. They fit snugly and the silicone feels much more durable than the rubber ones I've tried before.

Andrew S. ★★★★★

Finally, o-rings that actually survived my steam line without hardening after a week. The -80°F to +450°F range is exactly what I needed for the hot side, and the red color makes them easy to spot during maintenance.
