Washing Machine Appliance Waste Trap Blanking Cap with Washer

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).

The male 1 inch BSP thread that this item fits onto measures about 33.25mm on the scale of a ruler.

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