A. Installation of Pipe Fittings:

1. Tighten fitting by hand, then turn it 2-3 turns with a wrench until it reaches the desire torque listed.  If the fitting is not pre-coated with sealant, or is used and the sealant is not in good condition, apply Teflon sealant tape to the threads.

B. Installation of Tubing into Fitting:

1. Slowly push a clean and perpendicularly cut tubing into the fitting until it comes to a dead stop.

2. Pull the tubing back gently until the Grip Ring or Collet of the fitting grips onto the tubing and has a good seal.

3. Use Polyethylene, Polypropylene, Polyurethane or Nylon Tubing designed for instant fittings. 
4. Hard metal tubing can be used for all metal Stainless Steel and all Brass fittings if the tubing is pre-grooved.
