Isolate high-volume MDPE water lines swiftly with dependable, leak-free mechanical control.

Engineered for rigorous above- and below-ground installations, this heavy-duty stop tap connects directly onto 50mm outer-diameter plastic pipework without requiring hot works or specialist tooling. A great choice if you are looking for a reliable, hard-wearing isolation valve to manage main supply networks across agricultural land, commercial grounds, or large domestic properties.

Details & Practical Benefits

  • High-Integrity 50mm Mechanical Compression: Clamps securely onto standard 50mm metric MDPE pipe ends, delivering a dependable, pressure-tight seal that resists pull-out under fluctuating supply pressures.
  • Dual Above & Below Ground Rating: Moulded from robust engineered polypropylene and acetal components that withstand aggressive subsoil conditions, frost heave, and direct outdoor sunlight without rusting or degrading.
  • Positive Quarter-Turn Operation: Fitted with a high-visibility blue tee-handle that delivers smooth, immediate water shut-off, allowing rapid isolation during emergency pipe repairs or seasonal routine maintenance.
  • Full-Bore Flow Efficiency: Designed with an unrestricted internal chamber that reduces turbulence and friction loss, maintaining strong delivery volumes for livestock drinkers, farm outbuildings, and wash-down setups.
  • Integral Captive Seals: High-performance elastomeric seals seat evenly against the pipe surface, guarding against slow weeping and joint failure in saturated ground.
  • Direct Trench Assembly: Easily tightened using standard assembly wrenches or pipe grips, saving significant labour time when working inside tight excavation holes.
