Brass Fitting Operation Guide:
A. Installation of Pipe Fitting:
Apply an appropriate sealant onto the thread, tighten the fitting by
hand, then turn it 2 to 3 turns with a wrench until it reaches the
desire torque listed below.

B. Installation of Tubing into Fitting:
1. Slowly push a clean and
perpendicularly cut piece of tubing into the fitting until it
comes to a dead stop.
2. Pull the tubing back gently until the 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.
Hard metal tubing, such as Stainless Steel
tubing as can be used if the tubing is
grooved
first.
C. Removal of Tubing from Fitting:
1. Push in evenly on the two sides of the Release Button.
2. Pull out the tube while keeping the Release Button depressed.
3. To reuse tubing: cut off the lodged portion of the previously
used tubing evenly and perpendicularly.
D. Tubing Size Requirements:
Follow the tubing size tolerance below:
Polyurethane Tubing: specified fitting size ± 0.004” max. (± 0.1
mm max.)
Polyethylene Tubing: specified fitting size ± 0.006” max. (±
0.15 mm max.)
Polypropylene Tubing: specified fitting size ± 0.004” max. (±
0.1 mm max.)
Nylon Tubing:: specified fitting size ± 0.004” max. (± 0.1 mm
max.)
Pre-Grooved Metal Tubing:: specified fitting size ± 0.004” max. (±
0.1 mm max.)
E. Storage: Store Fittings in a dry, cool place and away
from sunlight.
