  • Choose between two tap threads: use the removable insert for a ½-inch BSP male tap, or remove it for a ¾-inch BSP male tap. Both sizes refer to the threaded tap outlet, not the hose diameter.
  • Keep the adapter on the tap: the male garden quick-connect plug accepts a compatible female hose socket. Disconnect your hose at that socket rather than unscrewing the tap adapter each time.
  • Brass body with a ribbed grip: the straight-knurled band gives you a grip when fitting the adapter. Its narrow plug and black sealing ring form the connection to the separate hose socket.
  • One adapter with its reducing insert: tap, hose and female hose connector are sold separately. Choose the hose socket to suit your hose and this plug profile; the adapter has no shut-off valve.

Description

Fits two tap sizes

Give your threaded garden tap a connection for a detachable hose. This brass tap adapter stays on the tap while your hose connects and disconnects at its own female quick socket.

The removable insert lets you choose a ½-inch or ¾-inch BSP female inlet. Fit the insert for the smaller male tap thread; remove it for the larger one. The garden quick-connect plug stays the same in either setup.

One adapter and its insert supplied. Tap, hose and female hose socket are separate.

Match the tap, then the hose

The insert screws into the adapter’s broad female inlet. Its smaller internal thread fits a ½-inch BSP male tap outlet. Without the insert, the adapter fits a ¾-inch BSP male outlet.

These are two alternative tap connections. The adapter does not have a ½-inch threaded hose outlet and is not a connector for bare hose.

For the hose side, use a compatible female garden quick connector. The optional brass socket above fits ½-inch hose; that hose bore is a separate choice from the BSP size on your tap.

Set up your connection

Select the inlet

Turn off the tap. Check its male thread and fit or remove the reducing insert as needed. Check the inlet seal is clean and undamaged.

Fit squarely

Start the thread straight using the ribbed grip. Do not force a mismatched thread or overtighten the adapter.

Connect the hose

Seat the female hose socket fully on the male plug, then open the tap gradually and check the joints. Close the tap and release pressure before disconnecting.

Before you choose

Do I need to buy two adapters?

No. One adapter is supplied with its removable insert. Choose the insert position to suit one matching tap at a time.

Does ½-inch mean the hose size?

Here it describes the smaller BSP tap thread. The hose socket is separate and must suit your hose’s bore as well as this male plug.

Where is the hose release collar?

On the separate female hose connector. The ribbed brass band on this adapter is a grip for fitting it to the tap.

Does the adapter stop the water when disconnected?

No. It has no shut-off valve. Turn off the tap and release pressure before removing the hose at its socket.

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.
