Product Information

Full details

The Plasson 7418 Imperial x Metric Coupler is designed for professional plumbers and water infrastructure contractors needing to transition between modern 32mm metric blue MDPE pipe and legacy 1-inch imperial alkathene piping systems. This high-grade coupler ensures a secure, leak-proof integration for diverse plumbing networks, though it requires specific attention to pipe cut quality to maintain its pressure-rated seal.

Extended Product Information

FAQs

Is this coupler suitable for drinking water?

Yes, this product is WRAS approved, making it safe for use in potable water distribution systems.

Can I use this for gas piping?

No, this product is specifically designed and rated for water distribution only.

Do I need special tools for installation?

No, this is a mechanical compression fitting designed to be installed by hand, though a pipe cutter is recommended for a clean end.

What is the maximum pressure rating?

The pressure rating is dependent on the pipe being used, but the fitting itself is built to handle standard water distribution pressures conforming to its certified standards.

Can this be buried underground?

Yes, the polypropylene material is resistant to corrosion and is suitable for direct burial in soil.

Troubleshooting

Leakage at the connection point

Ensure the pipe ends are cut square and are free from debris or scratches. Re-insert the pipe, checking that the O-ring is seated correctly.

Difficulty inserting pipe into the coupler

Ensure the nut is loosened sufficiently. If resistance persists, check for pipe ovality; a pipe re-rounder tool may be required for MDPE pipes.

Nut is difficult to tighten

Check the threads for dirt or grit. Clean the threads and ensure the nut is not cross-threaded before tightening.

Pros and Cons

Pros

Seamless transition between metric and imperial standards
High-grade polypropylene construction offers excellent durability
Easy to install without the need for specialized welding tools
WRAS approved for drinking water applications
High resistance to chemicals and environmental stress

Cons

Requires clean, burr-free pipe ends for a proper seal
Larger profile than standard inline couplings
Specific to 32mm and 1-inch sizing only

Setup, Compatibility & Care

Pipe Preparation: Ensure both the 32mm metric pipe and 1-inch imperial pipe are cut squarely. Remove any burrs or sharp edges from the pipe ends to prevent damaging the internal O-ring seal.
Insertion: Loosen the nut of the coupler, insert the pipe until it passes the resistance of the seal, and ensure the pipe reaches the internal stop.
Tightening: Hand-tighten the nut firmly. While tools can be used for final torque, avoid overtightening as it can stress the plastic threads.
Compatibility: This fitting is specific to 32mm metric MDPE and 1-inch imperial alkathene pipes; do not use with rigid PVC or metal pipes.
Care: Inspect the threads annually if the unit is accessible. Do not use petroleum-based lubricants on the O-ring; if lubrication is necessary for insertion, use a silicone-based plumber's grease.
