The Anti-Leak Irrigation Straight/Joiner Fittings 4mm

  • Compression Nut System
    A compression-style nut firmly clamps the pipe in place before the threaded section is tightened, creating a strong, secure connection that resists loosening.
  • Threaded Locking Mechanism
    Instead of relying solely on push-fit designs, these fittings use threaded or locking nuts to keep joints tight and stable, even when water pressure or movement varies.
  • Reliable Leak Prevention
    The anti-leak design ensures a tight seal that minimises drips, bursts, and water loss—ideal for systems that may be buried or subject to shifting.
  • 100% Compatible with Hozelock, Claber and Rainbird systems.
