Maintenance Checklist
Daily
Inspect for Leak-tight seal
• The main seal must be replaced more frequently depending on wear. Dismantling of the connector
for this purpose is not required. It is recommended that an O-ring pick be used for removal to avoid
damage to the groove. Clean groove if required and insert new O-ring.
• Connection should operate smoothly. If the connector is forced, remove from service.
• Check for contamination, bent or missing components.
• Check for leaks.
Weekly

• Check for any bent or missing components.
Periodic
• Inspect that all threaded components are tight and properly torqued.
• Check for any bent or missing components.
• Check for proper actuation of handle, collets and all moving components.
• Check for leaks.
