EPSI’s Port-Tite (TPSP) threaded port sealing plugs are designed to fit the most common standard and metric ports. The integrated flange and NBR O-ring not only provide a liquid and air tight seal, they also protect the port from damage and contamination during shipping and handling. Our polyethylene plugs are rugged, durable, and the perfect solution for plating applications. Plus, Port-Tite’s raised hex head and socket allow for application and removal by hand, socket, wrench, or a #2 Phillips screwdriver.
