Robert ★★★★★

The -40°F rating is what sold me, since my setup sits outside all winter. These 80 durometer rings feel firm but not brittle, and the 1.609" inner diameter matched my groove perfectly. No leaks after a week of pressure cycling.

Madison V. ★★★★★

These seals just dropped right in, and the 1.609" inner diameter fit the groove perfectly without any wrestling match. The HNBR material feels stout at 80 durometer, and knowing they hold up to 300°F gives me peace of mind for my hot oil lines.

Julian ★★★★★

The -40°F to +300°F range is exactly what I needed for a hot oil line, and the 80 durometer feels properly firm without being brittle. These 223s seated cleanly in the groove and have held pressure for two weeks straight so far.
