Washing Machine 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).

The male 1 inch BSP thread that this item fits onto measures about 33.25mm (1-1/4 inch) on the scale of a ruler.

This is NOT the size used for washing machine valves (look for a 3/4 inch BSP cap for that job).

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