Note: It is not necessary to disassemble this fitting for application. Merely insert tubing to stop and
tighten seal.
1. Cut tubing end squarely and remove the internal burrs.
2. Insert the tubing through the back of the nut all the way through the nut assembly to the tube stop
in the fitting body (see illustration). If the tubing does not enter the nut easily, loosen the nut one turn
and reinsert the tubing all the way to the tube stop in the fitting body.
3. Turn the nut hand tight.
4. Wrench tighten the nut 1½ - 2 turns.
5. All nuts must be retightened when the system reaches projected operating temperature.
Note: To ensure proper assembly, tubing MUST be fully inserted into the fitting body all the way to
the tube stop.
Note: Squeaking sound when tightening nut is normal. For pipe threaded connections, Teflon tape
must be used.
