Washing Machine Waste Trap Blanking Cap and Washer | 1 Inch BSP

Use this 1 inch BSP plastic blanking cap and washer to blank off a washing machine or dishwasher appliance waste / drain pipe connection (usually on the side of a trap, under your kitchen sink).

Please note, a 1 inch BSP thread measures 1-1/4 inch / about 32mm with a ruler (see pics).

This is NOT the item you need to blank / cap a washing machine water supply, that is usually 3/4 inch BSP cap (also in our store).

** BSP thread sizes are measured a special way - have a look at our information page for more details **
