DESCRIPTION
If a leak is detected in any of the quick connect fittings, it can be serviced using a service kit containing a new O-ring, collet, release ring and O-ring removal tool. The outer housing of the fitting cannot be serviced. The areas that have O-ring seals that can be serviced are:
^ Air compressor to drier: one O-ring.
^ Air spring solenoid to end cap: two O-rings each air spring solenoid.
^ Quick connect fitting: two O-rings at compressor air drier, one O-ring at each spring and junction block.
If air leaks are detected in these areas, remove components and install new O-rings.

2. After the collet is removed, use the removal tool to remove the old O-ring.

4. Then, insert the new collet, making sure the end with four prongs is inserted. Press the collet into position with finger pressure. install the new release button.
