Scarlett ★★★★★

Popped these into my espresso machine’s steam wand valve and they fit snugly, no leaks even at full pressure. The red silicone is easy to spot during cleaning, and the 70 durometer feels just firm enough.

Avery ★★★★★

These seal perfectly in my hot water setup, and the red color makes them easy to spot during maintenance. The 70 durometer feels firm yet flexible, and they've handled steam without any swelling.

Avery ★★★★★

I needed some red o-rings for a small engine project and the 70 durometer silicone feels pliable yet firm. The 22-pack is a decent quantity for the price, and they fit perfectly on the flywheel cover.
