• Installation of Pipe Fittings
  • Tighten fitting by hand, then turn it 2-3 turns with a wrench
    until it reaches the desired torque listed. If the fittings are not
    pre-coated with sealant, or is used and the sealant is not in good condition,
    apply Teflon sealant tape to the threads.

    Recommendation of Torque for Tightening Fittings
    Fitting Thread Size	Torque, lb-ft	Torque, kgf/cm
    10-32, M5 – M6	1.0 – 1.5	14 – 21
    NPT 1/8, R1/8	5 – 6.5	70 – 90
    NPT 1/4, R1/4	8.5 – 10	120 – 140
    NPT 3/8, R3/8	16 – 17.5	220 – 240
    NPT 1/2, R1/2	20 – 21.5	280 – 300

• Installation of Tubing into Fitting:
  • Slowly push a clean and perpendicularly cut tube into the fitting until it comes to a dead stop.
  • Gently pull the tubing back until the Grip Ring or Collet of the fitting grips onto the tubing and has a good seal.
  • Use Polyethylene, Polypropylene, Polyurethane, or Nylon tubing designed for instant fittings.
• Removal of Tubing from Fitting:
  • Push in evenly on the two long, oval sides of the Release Button.
  • Pull out the tube while depressing the Release Button.
  • To reuse the tubing, cut off the lodged portion of the previously used tubing in an even and perpendicular fashion.
• Recommended Tubing Material, Size, and Hardness Requirements:

  Tubing Material	Specified Size	Hardness (Durometer)
  Polyurethane	+/- 0.006″ (+/-0.15 mm)	Shore A 85 or higher
  Polyethylene	+/- 0.004″ (+/-0.1 mm)	Shore D 44 – D75
  Polypropylene	+/- 0.004″ (+/-0.1 mm)	Shore D 44 – D75
  Nylon	+/- 0.004″ (+/-0.1 mm)	Shore D 44 – D75
  Pre-grooved Metal Tubing	+/- 0.004″ (+/-0.1 mm)
