20mm MDPE kit
For 20mm outside-diameter MDPE pipe. The flange has a ½-inch BSP female socket for the tap’s ½-inch male inlet. A ¾-inch BSP female GEKA adapter screws onto the tap outlet.
Description
A fixed tap. A hose you can detach.
Bring your MDPE water supply to a wall-mounted brass bibtap, with a GEKA-type claw outlet ready for a matching hose connection.
The backplate keeps the tap in place. The crossbar handle controls the water, and the hose can be uncoupled without unscrewing the tap from its supply. Choose 20mm or 25mm to match your MDPE pipe’s outside diameter.
Match the pipe first
Each option includes the matching flange, tap and threaded claw adapter.
25mm MDPE kit
For 25mm outside-diameter MDPE pipe. The flange has a ¾-inch BSP female socket for the tap’s ¾-inch male inlet. A 1-inch BSP female GEKA adapter screws onto the tap outlet.
Mount, connect and use
Give the pipe and hose their own support so they do not pull on the tap.
Secure the backplate
Fix the three-hole flange to a sound wall or panel with suitable fixings. Prepare the MDPE pipe and follow the fitting instructions for pipe liners, insertion depth and tightening. Seal the BSP tap joint appropriately; sealing tape is not supplied.
Add the hose-side coupling
Choose a compatible GEKA-type coupling with a hosetail suited to your hose’s internal bore. Fit the hose fully over its tail and secure it with a suitable retaining clip. This mating coupling, hose and clip are purchased separately.
Close before uncoupling
With the tap closed and pressure released, align the clean sealing faces and twist the mating claw coupling into place. Check it is secure before opening the tap. Close the tap and release pressure again before disconnecting.
Connection questions
Does the GEKA adapter’s BSP size tell me which hose to buy?
No. Here, ¾-inch or 1-inch BSP describes the female thread attaching the adapter to the tap. It does not specify the hose bore. Match the GEKA claw connection, then select the hose-side coupling’s hosetail to suit your hose’s internal diameter.
Is the second claw coupling included?
No. The kit includes the wall flange, brass bibtap and threaded GEKA-type adapter on the tap outlet. The mating hose-side coupling is separate. Check the fittings and seals are suitable for your intended water supply and working conditions.

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.
