Connecting Lines & Fittings
NOTE:
Different fittings and connections are used on systems using HFC-134a refrigerant. Ensure all replacement parts match the connections of the system being worked on.
Always use a new gasket or "O" ring when connecting lines or fittings. Coat "O" ring with refrigerant oil and ensure it is not twisted during installation. Always use 2 wrenches to prevent damage to lines and fittings.
