Choosing and fitting
When selecting an O-ring of this type, verify that the inside diameter and cross-section match the groove dimensions exactly. The material compound and hardness must be suitable for the media and operating conditions. O-rings are not interchangeable across different assemblies, so ensure the part corresponds to the specific housing or valve. Before installation, inspect the groove for damage and lubricate the O-ring if recommended.
Signs of failure
A failed O-ring of this kind can cause loss of pressure, media escape, or impaired safety function. Signs include visible leaks at flange joints, filter covers, or valve bonnets, and a drop in system pressure. Check the O-ring for cuts, abrasion, or compression set during routine maintenance.
