Customer Reviews (4.8 / 5 · 5 reviews)

Isabella ★★★★★

The -350°F to +500°F range is exactly what I needed for a cryogenic fitting, and the 11 durometer makes them surprisingly pliable for PTFE. They seated snugly in the groove without any cracking during installation.

Benjamin ★★★★★

These worked perfectly to replace the old seals on my lab's distillation apparatus, handling the heat cycles without any deformation. The 0.736" ID was spot on for the fittings I needed.

James Z. ★★★★★

Finally got these to replace a worn-out seal on a high-temp valve, and they fit perfectly on the first try. The -350°F to +500°F range gives me confidence it'll hold up in extreme conditions.
