good Maintenance practices
• CGA standards for medical oxygen filling, CGA 870 and CGA 346/540 series connectors may require
periodic lubrication. Use Krytox or approved equivalent only.
• Maintain accurate and complete product maintenance records.
• In addition to these suggested maintenance guidelines, your companies overall safety and maintenance
requirements should be applied to FasTest gas connector products.
• It is recommended that gas connector products involved in high-volume filling be returned to FasTest for
a complete product inspection and required maintenance every 5 years.
• Adhering to a consistent product maintenance program will minimize product returns for inspection as
well as required maintenance costs.
• Minimize the use of soap solutions sprayed directly onto connector. These types of solutions cause
a build-up that can hamper proper connector operation. Also, avoid contacting connector with any
petroleum base chemicals that can cause product contamination.
• DO nOT EXCEED THE MAXIMuM OPERATInG PRESSuRE AS STATED In BOTH PRODuCT

connector Maintenance
The following maintenance guidelines apply to all FasTest gas connector products. Additional guidelines that
apply only to a specific CGA standard connector are noted.
• A daily, weekly and periodic inspection of the connector by a competent person is recommended.
Inspection should include wear of swivel joints, damage to the body, leak-tightness, ease of operation,
sufficient lubrication, wear, dirt accumulation and damage. (See Maintenance Checklist)
• If upon inspection a problem is noted, refer to the Troubleshooting Guide at the end of this manual.
DO nOT DISMAnTLE THE COnnECTOR.
• The manufacturer (FasTest) should refurbish connectors after 50,000 fill cycles.
• You may use only original FasTest spare parts that are designed for the application and are subject to
strict quality control. See Warranty.
Main seal
The main O-ring seal must be replaced at least every 1000 cycles. FasTest recommends a daily visual
inspection of the sealing O-ring, located at the tip of the filling nozzle. Inspect for tears or cracks in the
O-ring surface. Replace O-ring if tears or cracks are visible or verified. Some applications require more
frequent seal changes.
