Washing Machine Appliance Waste Pipe Trap Blanking Cap with Washer 1" BSP

Use this 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).

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

This cap has a 1 inch BSP female thread (measures about 1-1/4 inch with a ruler).

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