Our comprehensive range of Pipe and Tube Fittings is designed to provide seamless direction changes and leak-proof connections in the world’s most demanding fluid transmission systems.
We offer three distinct categories of fittings to suit every industrial need: Buttweld Fittings for permanent, high-flow piping; Forged Fittings (Socket Weld & Threaded) for high-pressure 2000# to 9000# applications; and precision Compression Tube Fittings for instrumentation. Our portfolio covers standard Stainless Steel (304L/316L), high-yield Carbon & Alloy Steel, and specialized Duplex 2205 / Super Duplex 2507 for seawater and corrosive chemical handling. For extreme resistance to pitting, we provide elite SMO 254 (6-Moly) fittings.
Strictly compliant with ASME B16.9, B16.11, and MSS-SP-75, our fittings undergo rigorous quality checks including Hydrostatic testing, Radiography, and Positive Material Identification (PMI). Whether you require elbows, tees, reducers, caps, or specialized instrumentation unions, our products are engineered to ensure long-term structural integrity under extreme mechanical stress and thermal fluctuations.
