1" Brass Water Butt Set with In-Line Valve, 20mm Hose Barb & Drill Bit

WB34-BRASS-KIT-013+DB+

Kit includes:

• 1 x Brass Connector 1" BSP Male to 3/4" BSP Female (WB-BR-34BSPF-1BSPM)
• 1 x PTFE Sealing Tape (PTFE)
• 1 x 3/4" BSP In-Line Valve (HCV34BSPM001BLACK)
• 1 x 20mm Pipe Joiner with 3/4" BSP Female Thread (STR20B34BSPF)
• 1 x 34mm HSS Hole Saw Drill Bit (DB34MM)

This brass reducer fitting transitions from 1" BSP male to 3/4" BSP female, ideal for connecting pipes in rainwater tanks and similar systems. Built from high-grade brass, it resists corrosion and delivers lasting performance in demanding environments.

If your tank has a 3/4" BSP female thread, the fitting can be screwed in directly. If not, use the supplied nut and washers after drilling a 33mm hole to ensure a watertight, stable connection.

To install, drill a 33mm hole, slide the connector through with the washer inside, and secure with the back nut. This method guarantees a firm, leak-free installation for custom water harvesting setups.

The 3/4" BSP In-Line Soft Touch Valve provides reliable flow control with minimal effort. It’s designed with male BSP threads for straightforward integration into irrigation or water storage systems, and the soft-turn handle ensures smooth operation even under pressure.

Constructed from high-quality plastic, this valve offers excellent durability and is resistant to chemical exposure, corrosion, and scale build-up, making it ideal for maintenance-free use in any environment.

The 20mm Pipe Joiner with 3/4" BSPF Thread is built from robust plastic for reliable use in irrigation systems. It connects 20mm piping to BSP-threaded valves or fittings, allowing flexibility in system design for both home gardens and professional installations.

The barbed end ensures a tight, secure fit with 20mm pipes, reducing the risk of leaks or disconnections. Installation is tool-free – simply push the pipe onto the barb for a tight grip.

PTFE (Polytetrafluoroethylene) tape is a plumber’s essential. This sealing tape ensures airtight connections between threaded fittings and is ideal for high-pressure or high-temperature systems. It’s simple to apply, chemical-resistant, and supports professional-grade sealing for water, gas, or air lines.

The 34mm HSS Hole Saw Drill Bit is engineered for precise cuts in metal, plastic, and wood. Built from high-speed steel, it offers excellent heat resistance and long-lasting sharpness. Its 34mm diameter is ideal for preparing tank holes for 1" BSP fittings.

Designed for smooth and stable performance, this drill bit reduces vibrations and delivers clean, accurate holes every time. It’s the perfect accessory for DIY or professional water butt installations and plumbing tasks.
