Description
Match the equipment thread to your hose run
Connect suitable 32mm pond hose to a matching 1¼-inch BSP female fitting with this straight black plastic adapter.
The external male thread is separate from the single-size ribbed hosetail. Check the port specification before choosing between threaded adapter sizes.
One adapter supplied. Hose, clips and sealing accessories are separate.
Check the thread and the working space
The male thread is nominal 1¼-inch BSP, with an external diameter of approximately 41.91mm in the dimension photo. It is not a 32mm-diameter thread.
The 80mm overall length includes a 50mm hosetail section. Leave room beyond the fitting for the hose and securing clip. The image shows two views of one adapter.
Assemble the connection in three checks
Start with the port, then check the hose and its support.
A matching female thread
Confirm that the equipment accepts 1¼-inch BSP male. Follow its specified sealing method and tightening instructions for plastic connections. This adapter has no independently turning swivel collar.
A suitable 32mm hose
Check the hose’s internal bore and wall profile so it can seat correctly over the ribs. Select the securing clip separately from the fitted hose outside diameter, following the hose instructions.
A supported hose run
Allow a gentle bend beyond the hosetail and avoid twisting or sideways loading at the port. Keep both joints accessible, secure the hose appropriately and inspect the finished assembly with water.
Checking the 1¼-inch BSP adapter
How is this different from the 32mm adapter with a 1-inch BSP thread?
Both can connect to suitable 32mm-bore hose, but their equipment threads are different. This version has a 1¼-inch BSP male thread, shown at approximately 41.91mm externally, and needs a matching female port. A 1-inch BSP female port is not the correct match. Check the equipment’s stated thread size rather than selecting by the hose bore alone.
Should a 1¼-inch BSP thread measure 32mm?
No. BSP uses nominal pipe-thread sizes rather than the hose-bore measurement. The external thread reference shown here is approximately 41.91mm for 1¼-inch BSP. Separately, the hose connection is for suitable 32mm internal-bore hose, also commonly called 1¼-inch. Those inch labels refer to different sizing conventions.
Is 80mm the clearance needed after fitting?
The 80mm measurement is the adapter’s overall length. The 50mm dimension shows the hosetail section from the shoulder towards the hose end. Installed clearance also needs to allow for thread engagement, hose seating, the securing clip and the hose bend. Use the photo as a fitting-size reference and check the complete layout around your equipment.
Can the hose be left unsupported because it has a clip?
A suitable clip helps secure the hose on the barb; it does not support the weight or sideways pull of the hose run. Arrange a gentle supported bend beyond the fitting and leave access to both joints. Choose the clip for the fitted hose outside diameter and wall profile, follow the fitting guidance and inspect the completed assembly with water.

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.
