Forged Square Head Plug

The Forged Square Head Plug redefines efficiency in high-pressure pipeline management, offering a robust solution for temporary sealing and test port closures with its innovative square head design optimized for secure wrench grip. Precision-forged from premium carbon steel or stainless steel, this plug combines exceptional tensile strength with corrosion resistance, ensuring reliable performance in demanding environments such as oil and gas refineries, chemical processing plants, and hydraulic testing systems. The square head allows technicians to apply maximum torque with standard tools, enabling rapid installation and removal during pressure testing, maintenance shutdowns, or emergency repairs—without risking slippage or equipment damage. Its tapered threads create a leak-proof seal under extreme pressures, making it indispensable for isolating sections of pipelines during integrity checks or containing aggressive fluids in industrial reactors.
