This item is a 1/8" MPT Brass Plug which can be used to block an 1/8" MPT (male Pipe Thread) hole normally found on a Heater Tube on Hot Tubs. This hole size is the same size as a Pressure Switch hole and would measure about 3/8" wide across the hole or the threads of the plug. Note: You will need to seal this plug with teflon pipe tape.
