The flange collar is part of the connection system of Emaux SS pumps and ensures the correct seating of the piping in the flange when tightening the union nut. Without this part there is a risk of leakage or mechanical damage to the piping during assembly.
The part is made of chemically resistant plastic that retains its elasticity even after years of contact with pool water. The precise dimensions guarantee compatibility with the original bodies of Emaux SS series pumps.
Replacing the collar is recommended whenever the connection is reassembled, or if mechanical damage is evident that could compromise the tightness of the joint.
