This 1" BSP water butt fitting with a 20mm MDPE straight joiner is a compact, reliable solution for rainwater systems. Built for tradespeople and DIYers alike, it delivers a secure, leak‑proof connection between a water butt tank and MDPE pipe.

• Included components:
  • 1 x Tank Connector with Washer, 1" BSPM
  • 1 x MDPE Straight Joiner, 20mm to 1" BSPF

• Reliable, leak‑proof fit – the BSP threaded tank connector is designed to tighten securely with its washer and nut, creating a robust seal at the tank outlet.
• MDPE straight joiner – 20mm MDPE to 1" BSP female connection enables a direct, straight run between standard MDPE pipe and a water butt outlet.
• Durable, weather‑resistant material – crafted from durable plastic and MDPE components, suitable for indoor and outdoor use where rain, sun and temperature variation occur.
• Compression connection – features compression style threading that provides a tight seal without requiring specialist tools; includes nut and washer for secure assembly.
• Pressure tolerance – MDPE PN10 rated fittings withstand up to 10 bar (approximately 145 psi), helping maintain system integrity under typical rainwater harvesting conditions.
• Versatile applications – ideal for connecting 20mm MDPE irrigation or rainwater supply lines to a water butt with a 1" BSP outlet, or for general low‑to‑moderate pressure water transfer between MDPE piping and tanks.

Practical notes – ensure a clean pipe and nut seating, hand‑tighten the nut against the washer for a first seal, then snug securely. This kit provides a straightforward upgrade or replacement for worn fittings on rainwater systems, helping keep your water storage leak‑free and ready for use.
