Had a small leak in a pneumatic actuator at work, and these O-rings sealed it perfectly on the first try. They handled the constant pressure of the dynamic seal without any issues, which was a relief. Exactly what I needed for the job.

Used a full pack resealing the hydraulic cylinders on my press and didn't have a single leak on the first test run, which never happens. The rubber's got just enough give to seat firmly in the grooves without tearing, even in the dynamic spots where the shaft moves.

Installed these in a hydraulic fitting last week and the seal held perfectly under pressure. The rubber feels dense and consistent, exactly what I needed for a reliable static application.
