Barb Only
One wall flange and brass hosetail, with no valve between them. Use your existing upstream shut-off to isolate this connection.
Description
From pipe to hose
Keep a hose connection where you water. This 20mm MDPE wall backplate and brass hosetail kit brings your pipe supply to a secure mounting point for ½-inch garden hose.
Choose a simple direct connection, or add a valve to switch the water off at the wall. All three options have the same 13mm brass hose barb; the difference is the control between the flange and hose.
Choose how you shut off the water
Every option takes 20mm OD MDPE pipe and the same ½-inch internal-bore hose.
Lever Valve & Barb
Adds a nickel-plated brass valve with a long red handle for local on/off control. Leave enough room for the full lever movement.
Bib Valve & Barb
Adds a nickel-plated brass valve with a compact black butterfly handle for local on/off control. Allow hand clearance around the handle.
Fit the hose. Support the pipe.
The supply pipe, BSP joint and hose barb each need the correct connection method.
At the wall
Isolate and depressurise the supply before fitting. Fix the three-hole backplate to a sound surface and support the MDPE pipe separately. Follow the pipe and fitting instructions for any liner, insertion depth and nut tightening.
At the threaded joint
The flange socket and hosetail use nominal ½-inch BSP threads; valve options add a matching male/female valve. Follow the component instructions for thread sealing and tightening. PTFE tape is not supplied.
At the hose
Choose ½-inch internal-bore hose, push it fully over the barb and secure it with a suitable clip. Route and support the hose so it does not pull sideways on the flange. Restore the supply gradually and inspect the joints.
Before you connect
Does 13mm mean the supply pipe size?
No. The 13mm label refers to the hose barb for nominal ½-inch internal-bore hose. The MDPE supply pipe is 20mm outside diameter. The ½-inch BSP thread joins the components together and is a nominal thread designation, not a 13mm measured thread diameter.
Does every option include a shut-off valve?
No. Barb Only has the flange and hosetail without a local valve; isolate it upstream before disconnecting the hose. The other two choices add either the long red lever valve or the compact black butterfly-handled valve. All hose, clips, pipe, fixings and sealing materials are separate.

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.
