Avery ★★★★★

I needed a batch of these for a hydraulic repair and the -40°F to +250°F range covers my shop's needs perfectly. Each ring feels consistently formed with no flash or deformities across the package.

Samuel R. ★★★★★

The 70 durometer rating is spot on for the hydraulic cylinder I rebuilt, and the package of 125 was more than enough for the job. Fit perfectly on the dash 161 groove without any issues.

Samuel G. ★★★★★

Used a few of these to fix a leaking valve on an old air compressor, and the 70 durometer hardness sealed it perfectly. The pack of 125 gives plenty of spares for future repairs.
