Description
A barbed lever tap
A nickel-plated zinc tap with a red lever and a downward-facing barbed outlet.
Pair it with the plastic tank adapter in the size and reach that suit your water butt.
½-inch or ¾-inch BSP. Standard or Extended.
Match the tank thread and hose
With the ½-inch BSP selection, both threads on the plastic adapter are ½-inch BSP. The tap has a matching ½-inch BSP male inlet and a nominal ½-inch hose barb. The Standard version is shown here.
The ¾-inch BSP selection instead pairs a ¾-inch male/female adapter with a ¾-inch BSP male-inlet tap and nominal ¾-inch hose barb.
The thread connects the tap to the tank fitting; the hosetail fits inside the hose. These are different connections, even where their nominal inch sizes match. Check the hose’s internal fit and use a suitable securing clip.
Choose the reach you need
Standard uses the shorter tank connector. Extended places a longer plastic tube between the tank wall and the tap, giving more clearance where the shape of the tank makes a close-mounted tap awkward.
The Extended connector is 50mm overall, with about 40mm usable projection. These dimensions apply to the connector, rather than the full adapter-and-tap assembly. The ¾-inch Extended kit is pictured here.
Either style comes with one back nut and two washers. Leave space for the red lever to move and for the hose to curve below the spout without pulling on the fitting.
Before you connect the hose
Check the mounting point, hose fit and operating space.
Match the tank
Confirm the size and gender of an existing tank outlet. For a new opening, check wall suitability, washer seating and room to reach the nut. The BSP thread name is not the required drill-bit diameter.
Fit the hose to the barb
The hose goes over the ribbed hosetail. Choose the correct internal fit for the selected ½-inch or ¾-inch outlet and retain it appropriately. This is a barbed connection, rather than a click-on garden-hose nipple.
Support and test
Leave clearance for the lever and support the hose so its weight does not strain the tap or tank wall. After fitting, check the tank mounting seal and threaded joint with water before leaving the connection in use.
Questions about the barbed lever-tap kits
Is the tap made from brass?
The tap body is nickel-plated zinc, with a silver finish and a red-sleeved lever. The tank adapter is black plastic. Each kit includes one tap with its barbed outlet fitting, one selected adapter, one back nut and two washers. It does not include separate brass and plastic hosetails to swap between.
Which hose size goes with each BSP option?
The ½-inch BSP kit has a nominal ½-inch hose barb; the ¾-inch BSP kit has a nominal ¾-inch hose barb. Match the hose’s internal fit to that outlet. The BSP measurement refers to the threaded tank and tap connections, while the hose barb is the part that fits inside the hose. Hose and clips are separate.
What is different about the Extended adapter?
It uses a longer plastic connector to bring the tap forward from the tank wall. The connector is 50mm overall, with about 40mm usable projection; the complete tap assembly is longer. Both Standard and Extended are offered in ½-inch and ¾-inch BSP, with the matching tap size in each case.
Does my hose need a quick connector?
For direct connection, the hose fits over the supplied barbed hosetail and should be secured appropriately for that hose. The outlet is not a male click-on nipple, so a female garden-hose quick connector does not attach to it in the same way. Check the selected hose size, leave a gentle hose route and support the line.

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.
