Installation

1 Ensure the pipe ends are free from debris and chamfered to a minimum of 1/8" x 45°

Fernco Chemical Couplings Installation Step 2

2 Mark the positions for the PTFE seals symmetrically, to ensure they will be located below the coupling bands

Fernco Chemical Couplings Installation Step 3

3 Apply the pipe seals onto the pipe, overlapping the ends

Fernco Chemical Couplings Installation Step 4

4 Install the FEP liner over the seals and apply hot air evenly to shrink the liner onto the pipe

Fernco Chemical Couplings Installation Step 5

5 Position the coupling centrally over the liner and tighten all clamps to 60 lb/in.
