Description
The MDPE Compression Repair Coupling is designed for joining two MDPE pipes of the same diameter where a section of pipe has been damaged or removed. Unlike standard couplings, this fitting is manufactured without an internal pipe stop, allowing it to be slid fully over one pipe and then repositioned centrally to complete the joint. Ideal for emergency repairs or system modifications, it ensures a secure, watertight seal. For optimal performance, the use of pipe liners (stiffeners) is strongly recommended to maintain joint strength and alignment.
Key Features & Benefits
- Designed for Pipe Repairs: Enables quick and reliable joining of two pipe ends in repair situations, with no need to fully dismantle the system.
- No Internal Pipe Stop: Allows the coupling to slide completely over one pipe end for easy positioning during installation.
- Secure Compression Joint: Delivers strong mechanical sealing using a grip ring and nitrile rubber gasket.
- Durable, UV-Stabilised Construction: Resistant to corrosion, environmental stress, and mechanical wear for long-term use.
- Tool-Free, Fast Installation: Simple push-fit design with no disassembly or heating required.
- Pipe Liner Compatible: Reinforces pipe ends to prevent deformation and ensure reliable sealing under pressure.
