Tapered Washer For 1-1/4" (32mm) Trap Outlet

1-1/4 inch trap outlet washer.

Coned / taper profile.

This washer makes the seal between the trap and waste pipe from 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.
