Product Introduction
Item No:
The stainless steel threaded plug is designed to securely seal the end of pipe systems in industrial, hydraulic, and fluid transfer applications. Manufactured from high-quality stainless steel, it provides excellent corrosion resistance, pressure stability, and long service life in harsh environments.
Available in NPT, BSP, square head, and hex head types, this pipe plug ensures reliable sealing performance for plumbing, oil & gas, and mechanical piping systems.
Products Description
The Stainless steel threaded plug is a threaded pipe plug with external threads on one end and a square head on the other end.
The Stainless steel square head plug is a closed plug that prevents flow, fully sealing the internal threads.
Designed for closing and terminating the ends of pipes, the square head solid plug ensures complete sealing.
1-inch external National Pipe Taper (NPT) threads, suitable for internal threaded pipes.
Made of high-strength 304 stainless steel.
The square head design provides additional leverage for use with a wrench.
The plug square is ideal for sealing intake manifold water ports, water pump ports, water temperature and oil sensor holes, and engine block openings.
