Steel Unions (Thread NPT)
Steel Unions (Thread NPT) are high-quality threaded pipe fittings designed to provide a secure, leak-tight, and easily detachable connection in piping systems using NPT (National Pipe Thread) threads. These unions allow quick assembly and disassembly without rotating the connected pipes, making them ideal for maintenance, repairs, and equipment replacement. Manufactured from premium carbon steel, they offer excellent mechanical strength, high pressure resistance, and long-lasting durability. Steel NPT unions are widely used in hydraulic systems, pneumatic installations, oil and gas, petrochemical plants, chemical processing, compressed air systems, power generation, and general industrial piping.
Customers may also search for these products using the following names: steel NPT union, NPT threaded union, National Pipe Thread union, threaded steel union, pipe union NPT, steel pipe union, NPT pipe connector, union coupling NPT, three-piece union, threaded pipe union, carbon steel union, industrial NPT union, hydraulic NPT union, pneumatic NPT union, high-pressure NPT union, ANSI NPT union, steel threaded connector, pipe disconnect union, male-female union fitting, threaded coupling NPT, union fitting, and carbon steel threaded fitting.
Steel Unions with NPT threads are available in a wide range of thread sizes and pressure ratings, making them suitable for low-, medium-, and high-pressure applications. Their precision-machined tapered NPT threads ensure reliable sealing, easy installation, and dependable long-term performance in demanding industrial environments.
You can order these products from POLBERIS, where you will find a comprehensive selection of premium-quality Steel NPT unions, threaded fittings, valves, and industrial piping components at competitive prices.
