Description
A connecting hose for your water butts
Plan the link between two suitable tanks with this 3/4-inch water-butt linking kit. It combines 19mm black corrugated hose with two straight tank fittings, nuts and sealing washers.
Select the length for your layout, from 1m to 5m. Each end uses a male 3/4-inch BSP tank thread and a barbed connection for the included hose.
One kit supplied. Tanks, clips and drilling tools are separate.
What makes up the connection?
The hose is flexible corrugated PVC, supplied as one selected length. Its ribbed outside allows it to bend along the route between the tanks. Smooth bore describes this hose type: the inside remains profiled, with smoothed ridges rather than a flat inner wall.
The two straight fittings connect the hose to the tank walls. Each has a male 3/4-inch BSP thread at the tank end and a barbed hosetail at the hose end, with one retaining nut and one sealing washer.
The photo shows the actual kit components. Clips and drilling tools are not part of the listed contents; choose any extras for your actual fittings, hose and tank installation.
Make room for the route and the fittings
Check both mounting positions before choosing a hose length or cutting any openings.
Check access inside
Allow room to position and secure a retaining nut inside each tank. Check the wall and sealing surfaces for suitability, and measure the opening against the actual fitting. BSP size is not the diameter of a hole saw.
Measure the whole route
Follow the planned hose path, including bends and the connections at both ends. Allow slack rather than stretching the hose across the gap. Choose one of the offered 1m, 2m, 3m, 4m or 5m lengths.
Support, secure and test
Keep the hose supported so its weight does not load the tank fittings. Check its fit on the hosetails and select any securing clips to suit. Test the tank seals and hose joints with water before leaving the link in service.
Choosing and fitting your kit
Does every length include both tank fittings?
Yes. All five options include two straight 3/4-inch BSP fittings, two nuts and two washers. The option you choose changes the hose length, from 1m to 5m.
Is 19mm the size of the hole for the tank fitting?
No. 19mm is the nominal internal size of the supplied hose. The tank fitting has a 3/4-inch BSP thread. Check the actual fitting, required opening and sealing surface before drilling your tank.
Will it fit any water butt?
Check your particular tank first. The wall, mounting position and space inside for the nut must suit the fitting. Tank capacity or the presence of a different existing outlet does not establish compatibility.
Are the inside walls of the hose flat?
No. This is smooth-bore type corrugated hose with profiled, smoothed internal ridges. It should not be confused with a completely flat-walled tube.

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.
