BSP Bulkhead Hose Fittings — Water Tank Connectors with Female & Male Thread, 1/2" to 2"
Drilling a hole in a water tank or barrel and ending up with a leaking connection is one of the most frustrating setbacks in any plumbing or irrigation project. Homeowners fitting rainwater harvesting tanks, smallholders connecting livestock troughs, and workshop technicians plumbing fluid reservoirs all need a bulkhead fitting that seals reliably through the tank wall without requiring specialist tools. These BSP bulkhead hose fittings are designed to do exactly that — thread through a drilled hole and clamp tight from both sides.
Each fitting uses British Standard Pipe (BSP) thread, available in female-to-female and male-to-female configurations across three pipe sizes: 1/2" (DN15), 3/4" (DN20), and 1" (DN25). Reducer variants extend the range to 1-1/4", 1-1/2", and 2" male connections. Multiple body types (A, A1, A2, B, C) reflect different flange geometries and sealing arrangements to suit various tank wall thicknesses and hose tail configurations. Packs of 1, 3, 5, 10, 25, or 50 pieces are available to match single installations or bulk plumbing jobs.
Typical applications include fitting outlet ports to polyethylene water storage tanks for garden irrigation, installing drain or fill connections on IBC totes and chemical barrels, plumbing coolant or fluid reservoirs in workshop equipment, and connecting hose tails to rainwater collection systems. The BSP thread standard ensures compatibility with the wide range of BSP-threaded valves, hose tails, and pipe fittings used across residential and light commercial plumbing.

Wide Size Range with Reducer Options
Standard sizes cover 1/2", 3/4", and 1" BSP in multiple body types. Reducer variants (1-1/4" x 1", 1-1/2" x 1-1/4", 2" x 1-1/2") allow step-down connections between different pipe diameters at the tank wall.
🔩
BSP Thread Standard
British Standard Pipe thread is widely used in residential and light commercial plumbing across the UK, Europe, Australia, and many other regions. These fittings connect directly to BSP-threaded valves, hose tails, ball valves, and pipe nipples without adapters.
🧱
Multiple Body Types (A / A1 / A2 / B / C)
Different flange and body geometries accommodate varying tank wall thicknesses and sealing requirements. Type A is a standard through-wall fitting; Types B and C offer alternative flange profiles. Confirm the type against your tank specification before ordering.
💧
Through-Wall Bulkhead Design
The fitting passes through a drilled hole in the tank wall and is secured by a locknut on the inside face, creating a sealed port. This design works with flat-wall tanks, barrels, and reservoirs without requiring welded fittings or specialist installation equipment.
📦
Flexible Pack Quantities
Available in 1, 3, 5, 10, 25, or 50-piece packs. Single-piece packs suit one-off repairs or prototype installations; bulk packs of 25 or 50 reduce per-unit cost for larger plumbing projects or trade stocking.
🔧
Straightforward Installation
Drill a hole to the correct diameter for the chosen pipe size, insert the fitting body, apply a sealing washer, and tighten the locknut by hand then wrench-tighten to compress the seal. Use PTFE tape or thread sealant on threaded connections for a leak-free joint.
