National Pipe Taper/ British Standard Pipe Taper (NPT/BSPT)

National Pipe Taper (NPT) / British Standard Pipe Taper (BSPT) fittings are precision-engineered threaded components designed to create a secure, leak-resistant connection in piping systems used across a wide range of industrial, commercial, and residential applications. These taper-threaded pipes and fittings are manufactured to meet strict international standards, ensuring high compatibility, durability, and performance under varying pressure and temperature conditions. NPT threads, predominantly used in the United States, feature a tapered thread profile that tightens as the connection is made, creating a reliable seal without the need for additional sealing components in certain cases, although PTFE tape or thread sealant is commonly applied for enhanced leak protection. BSPT threads, widely adopted in the United Kingdom and other parts of the world, operate on a similar principle with a slightly different thread angle and pitch, ensuring a tight and leak-proof joint in both high-pressure and low-pressure systems. These fittings are available in multiple materials such as stainless steel, carbon steel, brass, and galvanized steel, providing excellent resistance to corrosion, wear, and chemical exposure, thereby extending the service life of the piping system. Ideal for applications in oil and gas, water supply, HVAC systems, plumbing, and hydraulic installations, NPT/BSPT fittings offer versatility, reliability, and ease of installation, making them an essential component for efficient and safe fluid and gas transportation infrastructure.
