MDPE Wall Flange Kit 20mm is a complete, ready‑to‑install connection for 20mm MDPE piping, ideal for water supply and irrigation projects where a wall or surface entry is needed. It combines a robust wall flange, reliable Geka style fittings, and a controllable inline valve for straightforward, tool‑free assembly. What’s in the kit
- 1 x MDPE Wall Flange 20mm – ½" BSP (MDPEWF20-12BSPF)
- 1 x Geka ½"BSPM Connector (GK12BSPM)
- 1 x Geka ½" Hose Barb (GK13MM)
- 1 x Inline MDPE Valve 20mm (MDPEVALVE20) Key features and why they matter
- MDPE fittings with compression connections provide a tight, leak‑tight seal without requiring solvent welding or special crimping tools, saving time on site and reducing downtime.
- The wall flange allows secure mounting to a flat surface, extending your piping options to external taps, outbuildings, or equipment safely and neatly.
- The inline MDPE valve gives you direct flow control within the run, enabling isolation for maintenance without disturbing the rest of the system.
- Geka connectors (claw style) are renowned for quick, tool‑free assembly and disassembly, with brass bodies and rubber seals that deliver reliable sealing and durability in outdoor or harsh environments.
- The fittings are designed for MDPE piping up to 20mm and are rated PN10, meaning the assembly is capable of handling up to around 10 bars (approximately 145 psi) under suitable conditions. Who this kit is for
- Tradespeople fitting external water lines, irrigation mains, or temporary water supply connections.
- Housebuilders and landscapers installing outbuildings, sheds, or garden features that require a surface‑entry MDPE connection.
- Maintenance teams needing a ready‑made, interchangeable wall connection with easy isolation. Practical tips
- Ensure pipe ends are cut square and free of burrs before assembly; clean ends to maximise seal integrity.
- With the inline valve closed during installation, connect the wall flange and Geka components, then gradually open the valve to check for leaks.
- Use the claw coupling’s symmetrical design for quick alignment and a secure seal; replace seals if signs of wear appear after heavy use.
- Helpline support or datasheets can confirm compatibility with specific MDPE Grades and temperature ranges typical to domestic water systems.

Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
