316 Stainless Steel Tube Fittings Reducing Union (RU ) – CHIBIN Machine
Reducing Union enables tubing of different sizes to be connected, great for transition points in piping systems. A 316 Stainless Steel Reducing Union is a type of tube fitting that connects two tubes of different sizes together. It has a nut and a ferrule on each end that compresses against the tube when tightened to create a leak-tight seal.
Tube end Sizes are available from imperial units to metric system. CHIBIN specializes in stainless tube fittings, compression fittings, Rapid Fittings, Push-in Fittings, Hydraulic Fittings, Pipe Fittings, Quick Couplings, Valves, Nozzles and accepts ODM as well as ODM inquiry.
