Stainless Steel Union Fittings Manufacturer in India
View Dimensions of SS Compression Union, Refer Price list of ASTM A182 Hammer Union
Stainless steel union fittings are a fitting used to connect pipes that can be unscrewed into 2 separate pieces and screwed back together after both the joints are joined together. This method doesn’t cause as sort of deformation in the piping systems. A normal pipe union consists of 3 parts- a nut, a female, and a male end. This fittings are commonly used in piping systems, water supply, wastewater, fire protection systems, etc. We are the top Stainless Steel Union Fittings manufacturers in India who thrive in producing the best products at reasonable rates.

The SS Compression Union is the most common fitting used in plumbing and electrical conduit systems to join thin-walled pipes together. These fittings are very durable in extreme temperatures and pressures. They are very compatible with aggressive fluids and compression fittings. ASTM A182 Hammer Union is used in flow lines to prevent any leakage in piping systems. These unions can deal with pressures up to 20.000 psi and have material traceability. They are readily used in mud tanks, oil, and gas piping systems. The Stainless Steel Dielectric Union we produce is used in a piping system to slow down corrosion and deterioration caused as a result of galvanization and stray current.
SS Barrel Union is used to allow access for maintenance by breaking the line. The blocking nut is screwed onto a pipe allowing a section of the pipe to be removed for repairing or maintenance. We also produce the 1/2 Npt SS Union that can be customized into different dimensions and shapes as per our client's needs. If you want to know more about our products, or their pricing, contact us
