Description
Polished brass tap kit
A curved polished brass bib tap with a T-handle, downward barbed outlet and black plastic tank adapter for a suitable water butt.
Every option uses a ½-inch BSP tank connection. Choose a 13mm, 15mm or 19mm barb with a Standard or Extended adapter.
One selected kit supplied with a nut and two washers. Hose, clips and PTFE tape are separate.
Choose the hose outlet independently
The barb goes inside the hose. Its size is separate from the BSP thread that connects the kit to the tank.
13mm barb
The smaller outlet option, commonly described as a ½-inch hose connection. Check your hose’s internal size and fit before choosing a securing clip.
15mm barb
The middle outlet option. Check the hose specification and fit over the barb; do not confuse a hose barb measurement with rigid pipe or BSP thread sizing.
19mm barb
The larger outlet option, commonly described as a ¾-inch hose connection. It still uses the same ½-inch BSP tank adapter and tap inlet as the other options.
Leave room to use the tap
Standard uses the shorter tank connector. Choose it where the container already leaves enough clearance around the tap and hose.
Extended uses a longer male-to-female connector for more outward reach. It brings the tap further out from the container, which can help with handle access and hose clearance.
Check access inside the tank for the nut and washers as well as the space outside. The assembled position depends on the container and mounting arrangement.
The photograph shows the Extended 15mm option. The illustration above shows the Standard 13mm kit.
What changes between adapter types?
The reach changes; the tank thread and the three outlet choices remain the same.
| Feature | Standard | Extended |
|---|---|---|
| Tank-side thread | ½-inch BSP male | ½-inch BSP male |
| Adapter tap thread | ½-inch BSP female | ½-inch BSP female |
| Tap inlet | ½-inch BSP male | ½-inch BSP male |
| Barb choices | 13mm, 15mm or 19mm | 13mm, 15mm or 19mm |
| Adapter reach | Compact connector | Longer connector |
Match an existing tank outlet by its BSP thread size and gender. For a new opening, confirm a suitable container wall and sealing surface, and measure the actual adapter before cutting. The nominal ½-inch BSP size is not a drill diameter.
Fit the supplied nut and washers to suit the mounting, choose any suitable thread-sealing material separately, then check the tank seal, tap joint and hose connection with water. Support the hose so it does not pull against the plastic adapter.
Questions about the polished tap kit
Does the 19mm outlet need a larger tank thread?
No. The 13mm, 15mm and 19mm outlet options all have a ½-inch BSP tank adapter and a matching ½-inch BSP tap inlet. Outlet Size selects the hose barb, while Adapter Type selects Standard or Extended reach.
Are both adapter types included?
No. One kit is supplied in the selected adapter type and outlet size. It contains one plastic adapter, one polished brass bib tap with the selected barbed outlet, one retaining nut and two sealing washers.
Will a quick-connect hose end click onto this outlet?
The supplied outlet is a barbed hosetail for hose fitted over its ribs. It is not a quick-connect plug. Choose hose suited to the selected barb and a suitable securing clip; neither is included.
Is PTFE tape supplied with these kits?
No. These kits are supplied without PTFE tape. Select any suitable thread-sealing material separately for your fitting. The included nut and two washers are for the tank mounting, which also needs a suitable sealing surface.

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.
