The Plasson 50mm x 25mm mechanical reducing coupling is designed for professional contractors and irrigation specialists who need a reliable, high-pressure connection between differing sizes of PE pipe. This fitting excels in demanding environments like mining, industrial infrastructure, and large-scale farming due to its 16 Bar pressure rating and WRAS certification; however, users should note it is strictly for mechanical connection of PE pipes and requires proper pipe preparation to ensure a leak-free seal.

Yes, the Plasson reducing coupling is WRAS approved, meaning it is certified safe for use in potable water systems.
No, this fitting is specifically designed for mechanical connection of PE (polyethylene) pipe only.
The coupling is rated for working pressures up to 16 Bar.
No special tools are required, though a pipe cutter is recommended for a square, clean cut.
Yes, the mechanical design allows for disassembly and reuse, provided the O-ring remains in good condition.
Ensure the pipe is inserted fully past the O-ring and check that the pipe end is not scratched or burred.
Apply a small amount of non-petroleum-based lubricant to the pipe end and ensure the nut is fully backed off to allow the internal split ring to expand.
Verify that the threads are aligned correctly and that the O-ring is seated properly within the fitting housing.
To install, ensure the PE pipe is cut perfectly square and chamfer the end slightly to prevent damage to the internal O-ring seal. Insert the pipe past the seal into the fitting body until the pipe bottoms out, then hand-tighten the nut firmly. While the mechanical grip is strong, avoid using oversized wrenches that may crack the plastic body. Regularly inspect the joint for signs of seepage after initial installation, particularly in systems that experience high-frequency pressure cycling. Store couplings away from direct UV exposure to maintain material integrity over the long term.
