Customer Reviews (4.2 / 5 · 5 reviews)

Violet ★★★★★

The 70 durometer feels just right for a snug seal on our hydraulic fitting without being too stiff. I used one to replace a worn-out ring in a hot oil line that sees over 300°F, and it's held perfectly so far.

Hazel ★★★★★

Finally, a #229 o-ring that actually seals my high-heat valve application without melting. The FKM material holds up perfectly to the constant 350°F we run at, and the cross-section feels robust.

Lily ★★★★☆

Slightly stiffer than the generic rubber ones I’ve used, but the 400°F rating is why I grabbed these—they’ve held up fine in my hot oil setup so far. The cross-section is a touch thicker than I expected, which made seating them a bit snug, but they’re definitely not leaking.
