Why 3/8" Gaskets?

3/8" SAE fittings are the standard for R410A and other high-pressure refrigerant systems. The larger fitting size (compared to standard 1/4" fittings) provides better flow capacity and is specifically designed to handle the higher pressures of R410A systems. Proper gaskets are essential for maintaining leak-free connections.

When to Replace Gaskets:

• Regular Maintenance – Replace gaskets periodically to prevent leaks
• After Each Use – Some technicians replace gaskets after every job
• Visible Wear – Cracks, deformation, or hardening indicate replacement needed
• Leaks Detected – Replace immediately if leaks are found
• Preventive Replacement – Replace before critical installations

Benefits:

• Prevents Refrigerant Loss – Proper sealing saves expensive refrigerant
• Professional Service – Fresh gaskets ensure leak-free connections
• Cost-Effective – Pack of 10 provides excellent value
• Always Available – Keep spares in service van or workshop
• Quick Replacement – Simple, fast gasket changes
• Reduces Callbacks – Prevent leaks that cause customer complaints

How to Replace:

1. Disconnect hose from fitting
2. Remove old gasket from hose end
3. Inspect fitting for damage or debris
4. Clean fitting surface if needed
5. Install new gasket into hose end
6. Ensure gasket seats properly
7. Reconnect hose to fitting
8. Tighten to proper torque (do not over-tighten)
9. Check for leaks after connection

Maintenance Tips:

• Inspect gaskets regularly for wear
• Replace gaskets showing cracks or deformation
• Keep spare gaskets in service van
• Store gaskets in cool, dry location
• Avoid exposure to oils and solvents
• Replace gaskets annually as preventive maintenance
