Heater Tube Threaded Plug, 1/8"mpt, Plastic

This item is a 1/8" MPT Plastic 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: this plug already has teflon pipe tape on it.
