3/4" BSP Water Butt Fitting with 25mm MDPE Straight is a robust, ready-to-fit kit for rainwater harvesting and garden irrigation. It’s designed for tradespeople and DIYers who need a secure, leak‑free connection between a water butt and 25mm MDPE piping.

• 1 x Tank Connector with Washer 3/4" BSPM (BUTT34BSPM) – threaded tank connection with a washer for a solid seal against the tank surface.
• 1 x MDPE Straight Joiner 25mm - 3/4" BSPF (MDPESTR25-34BSPF) – straight MDPE joiner to link 25mm MDPE pipe to a 3/4" BSP female thread.

Key features and benefits

• Durable plastic construction delivers resistance to wear and weather, suitable for indoor or outdoor use without compromising performance.
• Leak‑proof potential comes from the integrated washer and nut, providing a secure, tight seal at the tank connection and a reliable joint at the MDPE straight joiner.
• Standard size compatibility uses a 3/4" BSP thread and 25mm MDPE pipe, aligning with common rainwater collection systems and irrigation setups.
• Pressure tolerance MDPE fittings are designed for up to 10 bar (PN10), offering confidence in garden and small‑scale irrigation pressures.
• Easy installation – threaded compression style connections require no specialised tools, simply tighten the nut against the washer to achieve a seal.
• Versatile use – suitable for connecting water butts to hoses, reels, or downstream irrigation lines, as part of a gravity‑fed system.

Typical applications

• Connecting a water butt to 25mm MDPE irrigation piping for garden watering.
• Converting or upgrading rainwater systems where a 3/4" BSP outlet is required.
• Repairs or replacements in existing MDPE-to-BSP fittings without replacing whole assemblies.

Practical notes

• Inspect washers for signs of wear; replace if cracked to maintain a leak‑free seal.
• A hand‑tighten to start, then secure with a wrench to avoid over‑tightening and potential damage to threads.
• Ensure the tank surface is clean and flat where the washer seats to optimise sealing.
