Description
A right-angle connection for 25mm hose
Bring flexible hose away from a compatible threaded port with this 25mm barbed elbow.
The black plastic body joins a 1-inch BSP male thread to a ribbed hosetail at a fixed 90° angle. Check the port, hose and available clearance together.
One elbow connector supplied. Hose and clips are separate.
Check the connection before choosing the route
A good fit starts with the port and hose measurements.
Identify the threaded port
Use a compatible 1-inch BSP female connection. Check its sealing requirements and the equipment’s fitting instructions; nominal inch sizes alone do not identify every thread type.
Match the hose bore
The other end is a 25mm hosetail. Check the hose’s internal bore, wall profile and securing method. Choose a length that reaches comfortably without pulling on the elbow.
Leave clearance at the bend
Allow room to assemble the fitting and seat the hose. Support the run and keep a gradual curve beyond the barb, rather than folding the hose sharply against the body.
Use the dimensions at the correct end
The hosetail section is approximately 30mm long. Its 25mm size describes the hose connection; the thread at the other end follows the BSP convention.
A 1-inch BSP male thread is around 33.25mm across the outside. That is why the threaded end does not measure 25mm, even though both ends may appear under an inch description.
The photograph shows two views of one elbow. After assembly, use the appropriate securing and sealing parts, inspect both joints with water, and keep access for future checks.
Before you fit the elbow
Why is the 1-inch thread wider than 25mm?
BSP uses nominal pipe-thread sizes. The 1-inch BSP male thread has an external diameter of roughly 33.25mm, as shown in the dimension photograph. The 25mm measurement belongs to the separate hose connection. Match the threaded end to a compatible 1-inch BSP female port, not to a 25mm hole chosen simply by measuring across it.
What hose should I choose for the barb?
Choose hose whose internal bore and construction are suited to this 25mm hosetail. The outside diameter of a hose includes its wall, so that is not the measurement to match. The suggested 25mm corrugated hose range offers several lengths; check its profile, the equipment requirements and the securing method before assembling the connection.
Can I rotate the hose end after fitting?
This is a fixed 90° elbow, not a swivel. Plan the hose direction and the sealing arrangement at the threaded port before assembly. Follow the equipment’s instructions for fitting plastic threaded connectors. Do not force the elbow beyond the appropriate tightening position to obtain an angle, and avoid using the hose to twist the body.
Does the dimension picture mean I receive two elbows?
No. It shows two views of the same connector so the hose and thread dimensions are visible. One elbow is supplied. Hose, hose clips and pump are separate. Measure the available space and check both connections before ordering; the photograph is a sizing reference rather than a guarantee of a fit with every port or hose bearing an inch label.

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.
