Universal Coupling
Universal Coupling is designed to connect two plain-ended pipes quickly and reliably. It allows different pipe materials and outside diameters to be joined within the specified OD range, making it suitable for pipeline repair, extension and field modification.
Materials & Relevant Standards
-
END RING : DUCTILE IRON GGG-50
-
BODY : CARBON STEEL / DUCTILE IRON
-
GASKET : EPDM / NBR / SBR
-
BOLTS & NUTS : CARBON STEEL / SS304 / SS316
-
COATING : EPOXY coating.

Problem Solved
In pipeline repair, extension and modification work, two plain-ended pipes often need to be joined quickly and reliably. A universal coupling provides a mechanical connection without welding, threading or flanged ends, helping reduce installation time on site.
How It Works
Both pipe ends are inserted into the coupling body. As the bolts are tightened, the end rings compress the gaskets around the outside diameter of each pipe. This creates a sealed connection between the two pipe ends.
Typical Applications
Suitable for water supply networks, wastewater pipelines, irrigation systems, industrial pipeline systems, pipeline repair, pipe extension and material transition between different pipe materials.
Selection Information
To select the correct coupling, please confirm the outside diameter of both pipes, pipe material, DN, PN, working medium and whether end restraint is required.
