Operating Pressure: Up to 16 bar at 20°C (size dependent)
Temperature Range: -10°C to +60°C
Pipe Compatibility: MDPE pipe of matching outer diameter
Liner Requirement: Pipe liners (stiffeners) are strongly recommended for all compression joints
Description
The MDPE Compression Reducing Coupling is designed to connect two MDPE pipes of different diameters, creating a secure, watertight joint between size transitions in a pipeline. Commonly used in water supply and irrigation systems, it offers high reliability and simple installation without the need for special tools or heat. For added joint integrity and to prevent pipe deformation, pipe liners (stiffeners) are strongly recommended.
Key Features & Benefits
Reduces Between Two Pipe Sizes: Allows seamless and secure transition between MDPE pipes of different diameters.
Tool-Free Push-Fit Design: Enables fast and efficient installation without the need for disassembly.
Corrosion-Resistant Build: Made from UV-stabilised, high-impact polypropylene for long service life.
Pressure-Resistant Sealing: Compression seal with nitrile rubber O-ring delivers a watertight joint under high pressure.
Enhanced Performance with Pipe Liners: Stiffeners improve alignment and joint strength, particularly under stress or temperature variation.
