20mm supply kit
MDPE inlet: 20mm pipe outside diameter.
Tap connection: ½-inch BSP male inlet into the flange’s matching female socket.
Hose barb: ½-inch internal-bore hose.
Description
Your hose, connected
Give the garden hose a fixed connection to your MDPE supply. This wall backplate and barbed lever tap kit combines a compression pipe inlet, a mounting plate and a silver tap with an easy-to-reach red on/off lever.
The tap body is nickel-plated zinc. Its hosetail fits directly inside the hose, secured with a suitable clip. Choose the 20mm or 25mm kit to match the supply pipe and the hose you want to connect.
Two matched connection sizes
Select by the MDPE pipe’s outside diameter, then check the hose bore at the other end.
25mm supply kit
MDPE inlet: 25mm pipe outside diameter.
Tap connection: ¾-inch BSP male inlet into the flange’s matching female socket.
Hose barb: ¾-inch internal-bore hose.
Plan the watering point
Leave clearance for the lever and space to reach each connection after installation.
Fix the flange
Isolate and depressurise the supply before fitting. Mount the three-hole backplate to a sound wall or panel with suitable fixings, and add separate supports for the MDPE pipe.
Connect the supply
Prepare the matching MDPE pipe and follow the pipe and fitting instructions for support liners, insertion and tightening. Use the appropriate sealing method when assembling the tap’s male BSP inlet with the flange’s female socket.
Secure the hose
Fit the correct-bore hose fully over the barbed outlet and tighten a suitable hose clip. Keep the hose clear of sharp bends at the tap. Restore the supply gradually, inspect the joints and check the lever’s on/off operation.
Check before ordering
Do I choose by the hose size or the MDPE pipe size?
The selector is the supply-pipe size: 20mm or 25mm outside-diameter MDPE. Each kit also has a specific hose outlet. Choose 20mm for a ½-inch internal-bore hose, or 25mm for a ¾-inch internal-bore hose. The BSP sizes describe the threaded tap-to-flange joint and are not direct measurements of the supply pipe or hose.
Is a quick connector or hose clip supplied?
No. This kit has a direct barbed hose outlet, not a snap-on connection. You receive one flange and its matching nickel-plated zinc lever tap. Add the correct hose and securing clip, MDPE pipe, supports, wall fixings and suitable thread-sealing materials separately.

What is BSP?
What is BSP thread size?
BSP (British Standard Pipe) is a nominal pipe-thread size, not a direct measurement of a fitting’s bore or outside diameter. For example, a ½-inch BSP male thread measures about 21mm across its outer thread crests.
These figures are approximate outside diameters of male BSP threads, to help identify the nominal size. They are not inch-to-millimetre unit conversions:
- 3/8" BSP → 16.66 mm
- 1/2" BSP → 20.95 mm
- 3/4" BSP → 26.44 mm
- 1" BSP → 33.25 mm
- 1.25" BSP → 41.91 mm
- 1.5" BSP → 47.80 mm
- 2" BSP → 59.61 mm
- 3" BSP → 87.88 mm
- 4" BSP → 113.03 mm
All our BSP threads are parallel (BSPP, to ISO 228), not tapered.
Measure across the outside of a male thread, then check its pitch and whether it is parallel or tapered. Diameter alone does not confirm compatibility. Check the product’s stated thread specification before connecting.
