Abigail Z. ★★★★★

The 80 durometer hardness feels just right for the high-temp application I needed them for, and they slid into the gland without any distortion. I used these on a hot oil line that gets up to about 250°F, and they've held their seal perfectly for two weeks now.

Ryan ★★★★★

Replaced the worn seals in my hydraulic press and these slid in perfectly, snug fit without any wrestling. The -40°F rating gives me peace of mind for the unheated garage in winter. No leaks after a week of heavy use, exactly what I needed.

Timothy A. ★★★★★

The 80 durometer feels exactly right for my hydraulic rebuild— not too soft, not too stiff. I've already used a dozen and they seat perfectly without any leaking.
