Compact Wall Flange Kit for 20mm MDPE with a ½” BSP outlet and in-line valve. Designed for tradespeople and housebuilders working with MDPE piping, it provides a secure, ready-made connection to walls and fixtures. What’s in the kit

• 1 x 20mm – ½” BSP Wall Flange (MDPEWF20-12BSPF)
• 1 x In Line MDPE Valve 20mm (MDPEVALVE20)
• 1 x Brass straight joiner 13mm - 1/2" BSPM (BRSTR13B-12BSPM)

Key features and benefits

The MDPE material is common for water supply and irrigation lines, offering chemical resistance and flexibility. The fittings are PN10 rated, meaning they’re designed to withstand up to 10 bar (about 145 psi) under typical conditions, which supports reliable performance in domestic and light commercial systems.

Installation and compatibility

These components are intended for use with 20mm MDPE pipe and utilise compression connections to deliver a leak-free seal without specialist tools. The wall flange secures the pipe to a flat surface, while the inline valve provides easy flow control within the run. The brass joiner combines a barbed hose connection with a BSP thread, enabling secure transitions between hose-like piping and threaded fittings.

Practical considerations

Note that this kit is not supplied with PTFE tape; purchase tape separately to aid thread sealing. Practical applications include garden irrigation, external taps, and water supply lines where a neat wall entry and accessible shut-off are desirable. The assembly helps reduce on-site cutting and misalignment risks by providing ready-made, correctly threaded components for MDPE systems.

In use, expect straightforward assembly with common MDPE piping practices, a compact footprint for tight spaces, and reliable performance from corrosion-resistant brass and robust MDPE fittings.
