ASME B16.11 Threaded Screwed Square Plug Manufacturer

What is a Square Plug?

A Square Plug is a type of threaded pipe fitting used to close the end of a pipe, valve, or opening in a piping system. It features a male-threaded body with a square-shaped head, making it easy to install or remove using a wrench. Square plugs are designed to provide a secure, leak-tight seal and are commonly used when a pipeline needs to be sealed temporarily or permanently without welding.

These plugs are manufactured in materials such as stainless steel, carbon steel, alloy steel, brass, and ductile iron to suit different pressure classes and service environments. The square head design provides strong grip and torque control, especially in tight or hard-to-reach spaces. They are available in NPT, BSPT, or BSPP threading standards, ensuring compatibility with a wide range of piping systems across industries.

Square plugs are widely used in oil & gas, chemical processing, water treatment plants, refineries, hydraulic systems, and HVAC networks. They serve as reliable closures for inspection points, pressure testing outlets, and drainage ports. Their simplicity, durability, and reusability make them essential components in both high-pressure industrial pipelines and general-purpose plumbing applications.
