32mm (1-1/4") Trap Inlet Flat Washer

Flat 1-1/4 inch trap inlet washer.

This washer makes the seal between the trap and waste fitting on your bathroom basin.

It is called a 1-1/4 inch washer, because it suits a waste trap with a 1-1/4 inch BSP thread, not because the washer itself measures 1-1/4 inch. The washer measures approx 39mm outside diameter.
