Description
A barbed hose tap
A white plastic tap with a blue lever and a fixed outlet for ½-inch hose.
The brass adapter connects the tap to a suitable tank thread or mounting point.
One kit, including the nut, two washers and PTFE tape.
Three sizes, three different connections
The 1-inch BSP male thread is on the outside of the brass adapter. Its ¾-inch BSP female internal thread accepts the white tap’s ¾-inch BSP male inlet.
The tap’s outlet is a fixed ½-inch hose barb, for hose with an approximately 13mm internal diameter. This hose size is separate from both BSP thread sizes.
Kit WB34-BRASS-KIT-006+ supplies one adapter with a brass back nut and two washers, one white plastic tap with a blue lever, and one PTFE tape roll. It is a single-size kit.
The barb is part of the supplied tap. You do not receive a separate quick connector, a hose or a hose clip.
Plan the route from tank to hose
Check the mounting area, hose bore and space around the lever before fitting.
Mount the adapter
Match an existing outlet’s actual thread. For a new position, check the adapter, wall thickness, washer seating and access to the back nut first. Nominal BSP sizes are not drilling diameters.
Fit the hose
Choose suitable hose with a ½-inch nominal bore, approximately 13mm internally. Check its fit over the barb and use a securing method appropriate to the hose. Support the hose to avoid strain on the tap.
Check the assembly
Leave room to operate the blue lever. Test the tank-wall seal, threaded joint and hose connection with water after assembly, then inspect them again when the tank is filled. No complete-kit pressure rating is specified.
Questions about this white barbed tap kit
What size hose does the tap take?
The fixed outlet is a ½-inch hose barb, intended for suitable hose with an approximately 13mm internal bore. Choose the hose by its internal fit over the barb, rather than its outside diameter. The kit does not include hose or a securing clip, so check both separately before fitting.
Why are 1 inch, ¾ inch and ½ inch mentioned?
They refer to three different connections. The brass adapter has a 1-inch BSP male external thread and a ¾-inch BSP female internal thread. The tap has a matching ¾-inch BSP male inlet, while its fixed outlet is a ½-inch hose barb. BSP thread names do not describe the hose bore or the size of a hole to drill.
Can I click a quick connector onto the outlet?
This version has a fixed hose barb for direct hose attachment, not a projecting male quick-connect nipple. A standard receiving quick connector does not attach to the barb in the same way. If you want a click-on hose connection, choose a tap kit with that outlet type or use an appropriately matched separate fitting.
What comes with this kit?
One brass tank adapter with a retaining back nut and two washers, one white plastic lever tap with its fixed ½-inch barb, and one PTFE tape roll are included. There is one kit size on this listing. A tank, hose, securing clip, drilling tools and additional connectors are not included.

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.
