Fitting Plugs are manufactured using premium materials like stainless steel, brass, carbon steel, or plastic to ensure strength and corrosion resistance. Stainless steel plugs are ideal for harsh industrial conditions, while brass plugs are commonly used in plumbing and instrumentation due to their anti-rust properties. Carbon steel plugs are preferred for heavy-duty, high-pressure applications.
These plugs are designed to close the ends of pipes, tubing, or ports, providing a reliable seal. They prevent the entry of dirt, dust, or moisture, protecting the system from contamination. By maintaining a tight closure, fitting plugs help preserve internal pressure and system integrity.
Fitting Plugs are widely used across industries such as oil & gas, chemical processing, hydraulic systems, pneumatic equipment, and water treatment plants. They are essential for sealing unused or maintenance ports in complex piping and instrumentation networks.
Thanks to their simple design, fitting plugs are easy to install or remove without specialized tools. They are available in threaded, compression, or push-fit types, allowing quick maintenance or system modification with minimal downtime.
Fitting Plugs are manufactured according to ASTM, ASME, SAE, and ISO standards, ensuring reliable performance and compatibility with other fittings. Each plug undergoes quality checks and pressure testing for safe operation under various conditions.
