Description
Polished brass
A curved brass bib tap with a traditional turn handle and downward hose outlet.
Choose the barb for your hose. Every option keeps the same tank adapter and tap inlet.
One selected kit, including PTFE tape.

Choose the barb to match your hose
The outlet changes. The ¾-inch tank adapter and ½-inch tap inlet do not.
13mm outlet
Kit WB12-BRASS-KIT-013+ has the nominal 13mm / ½-inch hosetail. Choose it for a hose with the corresponding internal bore. This is the kit shown in the contents photograph below.
15mm outlet
Kit WB12-BRASS-KIT-014+ supplies the 15mm hosetail. Use the listed metric barb size when checking your hose. The ⅝-inch size name is nominal; check the metric measurement when matching your hose.
19mm outlet
Kit WB12-BRASS-KIT-015+ supplies the nominal 19mm / ¾-inch hosetail. The wider hose outlet still connects through a tap with a ½-inch BSP male inlet.

What arrives with your order
Each kit includes one brass tank adapter with its back nut and two washers, one polished brass bib tap with the selected barbed hosetail, and one PTFE tape roll.
The brass adapter has a ¾-inch BSP male external thread and ½-inch BSP female internal thread. The tap screws into that internal connection through its matching ½-inch BSP male inlet.
The actual 13mm kit is pictured. Select 15mm or 19mm above for the corresponding hose outlet; you receive one tap and one chosen hosetail, not three interchangeable kits. Tank, hose, clips and drilling tools are separate.
Make room for the tap and hose
Check the mounting surface, the hose bore and space below the spout.
Check the tank outlet
Match an existing female thread to the adapter’s ¾-inch BSP male thread. For a new opening, check the wall, washer seating and access for the back nut before drilling. BSP thread names are not hole diameters.
Fit the correct hose
Match the hose’s internal diameter to the chosen barb. Check its material and wall construction, and use suitable clips where needed. This is a barbed connection; a female quick connector will not click directly onto it.
Support and test
Leave clearance to operate the handle and fit the hose onto the downward outlet. Support the hose rather than hanging its weight from the tap. Test the mounting seal and threaded connections with water after fitting.
Questions about the polished brass kits
Does changing the hose barb change the tank thread?
No. All three kits use the same ¾-inch BSP male / ½-inch BSP female brass tank adapter and a tap with a ½-inch BSP male inlet. The 13mm, 15mm and 19mm choices refer to the barbed hose outlet beneath the spout. Match the tank thread and hose bore separately.
Should I measure the inside or outside of the hose?
Match the barb to the hose’s internal diameter: the hose slides over the outside of the hosetail. Use the listed metric outlet size as your starting point and check the hose material and fit. The inch names shown alongside some options are nominal size labels, rather than outside-diameter measurements.
Will my quick-connect hose fitting click onto this tap?
No. The supplied outlet is a ribbed brass hosetail for the hose itself to fit over. It is not a male quick-connect nipple. If you want a detachable click-on hose connection, choose a tap kit supplied with that outlet type. Hose and suitable hose clips are separate from this kit.
Do I receive all three hose outlet sizes?
No. Choose one Barbed Outlet option above. You receive one tap with that selected hosetail, one brass tank adapter with its nut and two washers, and one PTFE roll. The three kit SKUs identify the 13mm, 15mm and 19mm outlet versions; they are not a three-tap bundle.

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.
