Description
A lever tap for your water-butt outlet
Bring a brass tank adapter and a barbed lever tap together for your garden water supply. The red handle operates the silver tap, while the ribbed outlet takes matching hose.
Choose a ¾-inch or 1-inch external adapter thread to suit the tank connection. Each option includes the matching tap, a retaining nut, two sealing washers and one roll of PTFE tape.
The adapter is brass; the tap body is nickel-plated zinc. Hose and hose clips are sold separately.
Which adapter size do you need?
The option name refers to the external tank thread, not the size of the hose outlet.
| 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 |
| Tap hose outlet | ½-inch barb | ¾-inch barb |
Match an existing tank thread by its BSP size and gender. If you are creating a new outlet, check the actual adapter, container wall and sealing surface before making a hole. Nominal BSP sizes are not hole-saw measurements.
The parts that make up your kit
The brass adapter connects the tank to the tap. Its nut and two sealing washers provide the mounting parts for a suitable container wall. Check access inside the tank as well as clearance outside.
The nickel-plated zinc tap has a red lever and a barbed outlet. The hose fits over the barb; there is no separate plastic hosetail or push-click connector in this kit.
One roll of PTFE tape is included for the appropriate threaded joint. Tape does not replace the mounting washers or the need to check the completed connection for leaks.
The photograph shows the ¾-inch adapter option. The larger kit uses the 1-inch adapter and matching ¾-inch tap shown in the comparison table.
Make room for the tap and hose
Plan the mounting position before assembling the outlet.
Check the connection
Confirm the tank thread, or a suitable position for a new opening. Allow room for the adapter nut, washers and tap handle; do not force mismatched threads.
Match the hose
Use hose suited to the selected tap’s barb. Check the hose fit and choose a suitable securing clip separately. Support the hose so it does not pull against the tank fitting.
Test before use
Check the adapter seal and threaded joint with water, then operate the lever and inspect the hose connection. Resolve any leaks before leaving the outlet in service.
Questions about the adapter and tap kit
Is the whole kit made of brass?
No. The tank adapter is brass and the silver tap body is nickel-plated zinc. The tap has a red lever handle and a barbed hose outlet. Both adapter-size options include a PTFE tape roll.
Does the 1-inch option have a 1-inch hose outlet?
No. The 1-inch option has a 1-inch BSP male tank adapter with a ¾-inch BSP female internal thread, a matching ¾-inch BSP male tap and a ¾-inch barbed hose outlet. The smaller ¾-inch adapter option has a ½-inch tap and barb.
Is this a click-on garden hose connection?
No. The supplied tap has a barbed hosetail for matching hose. Hose and clips are separate. If your hose uses a push-click connector, check the appropriate connection arrangement rather than expecting it to click directly onto the barb.
Can I use it to make a new tank outlet?
The adapter has a retaining nut and two washers for mounting on a suitable container wall. Check the wall, sealing surface, available thread length and access to the nut before cutting. Measure the actual fitting; the option’s BSP size is not a drill diameter.

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.
