Description
A simple hose outlet for your water butt
A white plastic tap with a blue lever, supplied with the black tank adapter and mounting parts for your selected reach.
Connect nominal ½-inch hose directly to the ribbed outlet. The tap and both adapter choices use matching ¾-inch BSP threads.
One Standard or Extended kit supplied. Hose and securing clips are separate.
Two different sizes, two different jobs
The tank thread and the hose outlet are measured differently.
Match the tank thread
¾-inch BSP describes the threaded tank adapter and tap inlet. BSP is a nominal thread standard: it does not mean the thread measures ¾-inch across, and it is not a drill-hole measurement.
Match the hose bore
The ½-inch barb fits a hose with a nominal ½-inch internal diameter, commonly rounded to 13mm. Check the inside of the hose, rather than choosing by its outside diameter alone.
Check the connection style
This tap has an integral ribbed hosetail. The hose fits over it directly; a female garden-hose click connector does not clip onto the barb. Use a suitable securing clip where needed for the hose.
Keep the mounting close to the tank
The Standard kit uses a short black male/female adapter. The tap’s ¾-inch BSP male inlet screws into its female end; the adapter’s male side is the tank-side connection.
Choose this reach when it leaves enough room for the lever, hose and tank moulding. Check the size and gender of an existing outlet before replacing its fitting: water-butt connections are not all the same.
For a new opening, confirm that the tank wall is suitable, both washers can seat properly and you can reach the back nut inside. Plan the position before drilling, and test the fitted assembly with water.
Need more clearance? Choose Extended
The Extended option moves the tap further from the tank wall. Its plastic connector measures 50mm overall, with about 40mm usable projection. These are connector measurements, not the overall length of the assembled tap kit.
Both options use the same white-and-blue tap and ½-inch hose outlet. Check the hose has room to bend below the spout without kinking, and support it so a pull on the hose does not strain the plastic mounting.
You receive one selected adapter, one tap, one back nut and two washers. The hosetail is part of the tap. Hose, clips, PTFE tape and tools are separate.
Questions about the white tap kit
Is there a ½-inch BSP adapter option?
No. This product’s two options are Standard and Extended, both with a ¾-inch BSP tank adapter and a tap with a matching ¾-inch BSP male inlet. The ½-inch measurement refers to the hose barb, not the threaded adapter. Check the tank-side thread size and gender before choosing the mounting reach for your installation.
Will my hose click onto this tap?
This tap has a ribbed hose barb rather than a male click-on nipple. It is intended for a direct hose connection using nominal ½-inch internal-diameter hose, commonly rounded to 13mm. A female garden-hose quick connector will not clip directly onto that barb. The hose and any suitable securing clip are supplied separately.
Does the Extended option use a different tap?
No. Both kits use the same white plastic tap with blue lever, ¾-inch BSP male inlet and integral ½-inch hose barb. The difference is the black mounting adapter’s reach. The Extended connector is 50mm overall with about 40mm usable projection. Choose it if the shorter fitting would leave the lever or hose too close to the tank’s shape.
Can I fit it through a new hole in a water butt?
First check that the tank wall is suitable, the washers will sit flat and the back nut can be reached from inside. Choose a position that leaves room for the tap and hose. The ¾-inch BSP option name is a nominal thread size, not a drill size. Confirm the opening needed for your fitting before drilling, then test the mounting seal and water connections after assembly.

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.
