Description
The MDPE Compression Coupling is designed to connect two lengths of MDPE pipe of the same diameter, forming a secure and leak-free joint. Suitable for water supply, irrigation, and utility applications, this fitting quickly installs and delivers long-lasting performance in above- and below-ground systems. Manufactured from high-quality polypropylene, the coupling offers excellent resistance to corrosion, pressure, and environmental conditions. For optimum sealing and structural reliability, the use of pipe liners (stiffeners) is strongly recommended.
Key Features & Benefits
- Same-Size Pipe Connection: Securely joins two MDPE pipes of the same diameter in a straight-line configuration.
- Reliable Compression Seal: Provides a strong mechanical and watertight seal using a push-fit compression design.
- Quick and Easy Installation: Requires no disassembly or special tools—ideal for field use and system repairs.
- Tough and Corrosion-Resistant: Constructed from UV-stabilised polypropylene for durability in harsh environments.
- Enhanced with Pipe Liners: Use of stiffeners improves joint alignment and prevents deformation under pressure.
