Fitting Assembly Guidelines

Copper plate type fitting or non-asbestos plate type fitting for gas (for annular coated tube)

  • Step 1 : Cut Pipe To Length
    Cut the pipe to the desired length, leaving 1 inch for placement of the fitting attachment Use stainless steel tube cutter. Clean any jagged edges or burrs.
  • Step 2 : Remove Pipe Jacket
    Strip the yellow piple jacket back 3~4 valleys from the end of the tubing.

    Use a utility knife, DO NOT USE A TUBE CUTTER.

  • Step 3 : Assemble Flange Nut
    Slide Flange Nut over the tubing with the thread end pointing toward the end of tubing. Make sure the flange of the nut to cover the yellow jacket and secure the tubing
  • Step 4 : Place Clamp Ring
    Open the ring wide enough to fit in the groove behind the first or second ring and use pliers to clamp the brass ring in place. Make sure to put pressure with pliers all 180°around on the ring, so the ring can stay tight and doesn’ t spin around on the tubing.
  • Step 5 : Assemble Socket
    Put sealing solution on tapered thread of socket. Screw tapered male thread of the socket into female thread of piping systme or boiler, and tighten clockwise with maximum torque using a crescent wrench.
  • Step 6 : Get Fitting Ready To Assemble
    Make sure a clamp ring & flange nut assembled properly on the tubing, and copper plate stays firmly inside the socket.
  • Step 7 : Tighten Up Flange Nut
    Put the female parallel thread of the flange nut onto the male parallel thread of the socket. Use a crecsent wrench to tighten up the flange nut clockwise with high torque upto the end of the male parallel thread.
