Inspecting and Replacing the PTFE Tubes and
Push-To-Connect Fittings
Read the
“Maintenance and Repair Safety” section prior to
performing any work on the system (beginning on Page 38).
Wear appropriate Personal Protective Equipment and follow
all industry standard safety practices.
The scavenge, pressure control and throttle control tubes are made of
Polytetrafluoroethylene (PTFE) and are within specification to work with
VMAC compressor oil and to withstand the high pressure and operating
temperatures generated by the compressor. Standard air brake hose is not a
suitable replacement.

PTFE Tubing must be cut to length using the proper tubing cutter. Side
cutters and other tools tend to leave sharp edges and crush the tubing.

To properly insert the PTFE into the push-to-connect fitting, lubricate the
tube, push it firmly into the fitting until it has fully seated, then slide the
collet back along the tube to lock it into place,

Ensure the tube does not have any play to prevent the O-ring from
wearing.
Lubricate the tube and firmly push it into the fitting so that the
tube fully seats in the fitting. Slide the collet out, away from
the body of the fitting to lock the tubing in place. Ensure the
tube does not have any ‘play’ to prevent the O-ring from
wearing.
