The Wall Flange Kit 20mm MDPE + Bib Valve + ½” Geka is a ready-to-use connection solution for MDPE piping, crafted for tradespeople installing water supply and irrigation systems. It combines a 20mm MDPE wall flange, a ½” BSP bib valve, and a Geka-type fitting for fast, reliable field connections. Contents
- MDPE Wall Flange 20mm – ½” BSP (MDPEWF20-12BSPF)
- Bib Valve ½” BSP (BRVALVEBIB12BSPM-F)
- Geka Type Fitting ½” BSPM (GK12BSPM) Why it matters
MDPE fittings are designed for durability, flexibility, chemical resistance and leak-free sealing via threaded compression connections—no special tools required. The wall flange allows a pipe to terminate neatly at a flat surface, expanding installation options and tidiness on site. The MDPE PN10 rating means fittings are engineered to withstand up to 10 bars (about 145 psi), suitable for domestic mains and irrigation runs subject to modest pressure spikes. These components resist corrosion from chemicals and weather, reducing maintenance needs in exposed or outdoor settings. Valve performance
The Brass Nickel Plated Butterfly Valve provides a robust, corrosion-resistant flow control point. With ½” BSP threads, it mates easily to standard pipework, and the simple twist-on/off action enables quick isolation or flow adjustment in service lines, RV/holiday homes, or temporary installations. Geka-style quick-connect
Geka-type connectors offer fast, tool-free assembly with secure seals. The claw coupling design interlocks symmetrically, making hose-to-pipe connections straightforward on busy sites. Brass construction delivers good durability and corrosion resistance in challenging environments, ensuring long service life in water and light chemical applications. Ideal uses
- Connecting MDPE mains to indoor/outdoor taps or meters
- Irrigation line spur connections from a wall outlet
- Temporary or semi-permanent water service installations where rapid disassembly might be needed This kit delivers a practical, field-ready solution for efficient, leak-controlled MDPE installations.

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.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
