Abigail ★★★★★

My gauge showed the inner diameter right at 3.484 inches, perfect for a snug fit on a hydraulic coupler I was rebuilding. The 75 durometer feels firm yet pliable, and the brown color makes them easy to spot against darker metals.

Isabella ★★★★★

The high-temp rating up to 400°F is exactly what I needed for my oven gasket replacement. These 3.484-inch rings fit perfectly and the brown color makes them easy to spot against the metal.

Penelope ★★★★★

Finally found o-rings rated for my high-temp hydraulic system that actually stay flexible under load. The 75 durometer feels just right on the seal face, and so far no leaks after a week of cycling. These are the exact AS568-238 dimensions I needed.
