Eli R. ★★★★★

These have been holding up perfectly under constant steam exposure in our commercial kitchen, the red color makes them easy to spot during disassembly. The 70 durometer gives just enough flexibility without being flimsy.

Scarlett B. ★★★★★

Finally, o-rings that stand up to the high heat from my commercial steamer without getting brittle. The 70 durometer silicone feels substantial and the 5.609" inner diameter matched perfectly. First batch ran for three hours straight with zero leaks.

Ellie ★★★★★

Installed these on my brewing kettle lid and the -80°F to +450°F range gives me peace of mind during high-heat sanitizing cycles. The vivid red color makes them easy to spot if they ever pop out during cleaning.
