Customer Reviews (4.0 / 5 · 5 reviews)

Grace ★★★★★

We used these on a hot water recirculation pump at the plant, and the EPDM held up fine at 200°F without any swelling. The 3.85" inner diameter fit perfectly on the flange.

Nicholas I. ★★★★★

I needed a high-temp seal for my solar thermal system, and these EPDM rings handled the constant 250°F water without any issue. The 0.21" cross-section feels robust and they seated perfectly in the groove.

Aurora J. ★★★★☆

The 0.21" cross-section on these is beefier than I expected, which gives me confidence they'll hold up on my compressor fittings. They seated easily with no twisting, and the price for a 26-pack is solid.
