Description
Reducer Socket 63x50mm local
Coupling Reducing PPRC GM GM local manufacturing PPRc Pipe and fittings, Available
in Karachi Pakistan. Size 25mm to 63mm
What is Reducer Socket 63x50mm local ?
A pipe fitting used to connect two pipes of different diameters in PPRC (Polypropylene Random Copolymer) piping systems. The Reducer Socket provides a smooth transition from 63 mm OD pipe to 50 mm OD pipe, maintaining pressure and flow integrity.
This specific item is local GM (General Manufacturing) PPRC, commonly used in Pakistan for water supply and plumbing systems.
Key Features

-
Size: 63 mm × 50 mm (outside diameter of pipes it connects)
-
Type: Reducer Socket / Coupler (socket-weld fitting)
-
Jointing Method: Fusion welding (butt/socket fusion) with PPRC welding machine
-
Pressure rating: PN16 (16 bar at 20°C) typical for local PPRC fittings
-
Temperature range: -20°C to +95°C (continuous), short peaks up to 110°C
-
Chemical resistance: Excellent resistance against scaling, rust, electrolytic corrosion, and most chemicals
-
Non-toxic & hygienic: Suitable for potable water applications
-
Service life: 50+ years (if properly installed at rated conditions)
Description / How it Works
-
The reducer socket allows the connection of a 63 mm PPRC pipe to a 50 mm PPRC pipe.
-
The pipes are inserted into each end of the socket and joined using heat fusion welding, ensuring a leak-proof, homogenous joint.
-
This type of connection eliminates the risk of leakage (unlike threaded joints) and ensures smooth flow transition without turbulence.
