Plastic Threaded Plug for Heater Tube - 1/8"mpt Hot Tub Spa Part

Designed to seal off a 1/8" MPT (Male Pipe Thread) opening typically located on hot tub heater tubes, this plastic plug provides a reliable blocking solution. The threaded opening measures approximately 3/8" in diameter and matches standard pressure switch port sizing. Factory-applied teflon pipe tape is already installed on the threads for immediate use, ensuring a watertight seal without additional preparation.
