A/C Coupler O-ring: Service and Repair
O-ring Connections
1. GENERAL
The following points should be kept in mind when assembling O-ring connections.
1. Avoid unnecessary handling and contact of O-rings with your hands, since even clean fingers contain body acids, which can contaminate the
O-ring surface.
2. Do not handle O-rings with gloves, shop towels, etc., since lint particles may cling to the O-ring, possibly causing a leak upon assembly.
3. Always lubricate O-rings before assembly to allow the O-ring to seat itself properly.
4. Be certain to use torque wrenches when tightening O-ring fittings, because overtightening can not only damage the O-ring, but ii can distort the
tube end as well.
2. REMOVE PROTECTIVE SEALS
Just prior to making the connection, remove the protective seals.
CAUTION: If for any reason you have to stop before making a connection, recap the tube, component or fitting.
Visually inspect the O-ring surface, the O-ring mating surface, the threads and the connection points. If a defective part is found, replace it.
The O-ring must sit square against the tube bead. If necessary, slide the O-ring into proper position with clean hands.
