Description
A brass tap for your garden water supply
Fit a suitable water-butt outlet with a brass tank adapter and brass bib tap. Turn the T-shaped handle to open or close the tap, and connect matching hose to its ribbed brass outlet.
Choose the adapter by its external tank thread: ¾-inch or 1-inch BSP. Each size comes with a matching tap, a retaining nut, two sealing washers and one roll of PTFE tape.
The hose outlet changes with the kit size. Check the comparison below before ordering hose or replacing an existing fitting.
Start with the tank connection
The adapter size is different from the tap inlet and hose barb. Use this table to match the complete kit.
| Connection | ¾-inch option | 1-inch option |
|---|---|---|
| Tank-side thread | ¾-inch BSP male | 1-inch BSP male |
| Adapter internal thread | ½-inch BSP female | ¾-inch BSP female |
| Tap inlet | ½-inch BSP male | ¾-inch BSP male |
| Hose outlet | ½-inch barb | ¾-inch barb |
For an existing threaded tank outlet, match its BSP size and gender. For a new opening, check the actual fitting and container before cutting. A nominal BSP thread size is not a drill diameter.
What arrives in your kit?
One brass tank adapter with a retaining nut and two sealing washers. Check that your tank provides a suitable sealing surface and enough access to position the mounting parts.
One brass bib tap with a T-shaped turn handle and barbed hose outlet. The hose fits over the barb; choose the hose and securing clip separately to suit the selected option.
One roll of PTFE tape for the appropriate threaded connection. The tape does not replace the tank-mounting washers.
The photograph shows the larger kit: a 1-inch tank adapter with a ¾-inch tap and hose barb. The garden illustration above shows the smaller option.
Allow space for the handle and hose
A little planning makes the outlet easier to fit and use.
Check the mounting
Match the tank thread or confirm a suitable new mounting position. Check wall thickness, sealing surface and access to the nut before making an opening.
Fit matching hose
Use hose suited to the selected barb and a suitable securing clip. Allow enough clearance below the tap and support the hose so it does not pull against the fitting.
Test with water
Inspect the tank seal, threaded joint and hose connection. Operate the handle and resolve any leaks before leaving the outlet in use.
Questions about the brass bib tap kit
What does Adapter Size refer to?
It is the adapter’s external BSP thread at the tank. The ¾-inch option has a ½-inch BSP female internal thread and a matching ½-inch tap. The 1-inch option has a ¾-inch BSP female internal thread and a matching ¾-inch tap.
Do both options take the same hose?
No. The smaller ¾-inch adapter option has a ½-inch hose barb; the larger 1-inch adapter option has a ¾-inch hose barb. These are nominal hose sizes. Check your hose fit and select a suitable securing clip separately.
Will a click-on hose connector fit directly?
The supplied outlet is a barbed hosetail for hose fitted over the ribs. A push-click hose connector is not supplied. Check the connection arrangement if you want to use an existing quick-connect hose system.
Are the washers and PTFE tape included?
Yes. Each kit includes one adapter retaining nut, two sealing washers and one roll of PTFE tape, along with the brass adapter and bib tap. Fit the washers to suit the tank mounting and use the tape for the appropriate threaded joint, then test the assembly with water.

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.
