Product Information

Full details

The Plasson Adapter Imperial Conversion Set is designed for plumbing professionals and DIY enthusiasts tasked with integrating modern MDPE piping systems with traditional Imperial Class C High Density pipes. This kit provides a durable, watertight connection for water supply networks without requiring specialized installation tools or complex machinery. While it offers a versatile and cost-effective solution for legacy infrastructure upgrades, users must ensure they verify the specific diameter and pressure rating of their existing pipework before installation to guarantee compatibility.

Extended Product Information

FAQs

Can this be used on gas lines?

No, this product is designed specifically for water supply systems and is not rated for gas applications.

Do I need special grease to seat the fitting?

Plasson fittings are designed to create a seal through mechanical compression. Using lubricants is generally not recommended unless specified for the specific pipe material.

Does this require a wrench to tighten?

While the design is simple, using a standard pipe wrench may be necessary to ensure the coupler is tightened sufficiently to provide a watertight seal.

Is this compatible with Class D pipe?

This specific range is designed for Class C High Density pipes. Always verify the classification of your pipe before installation.

Can it be buried underground?

Yes, these fittings are constructed for durability and are suitable for use in standard underground water supply installations.

Troubleshooting

Joint leaking after tightening

Ensure the pipe end is cut perfectly square and there is no debris on the sealing surface. Re-tighten the coupler, ensuring even compression.

Fitting will not slide onto pipe

Verify that you are using the correct size conversion set for your specific pipe diameter; Imperial and Metric measurements can look similar but are not interchangeable.

Pros and Cons

Pros

  • Simple, tool-free installation process
  • Highly durable construction for long-term reliability
  • Effective at connecting older imperial pipe systems to modern metric PE
  • Reduces inventory complexity with versatile fitting design
  • Compliant with BS3284/67 industry standards

Cons

  • Requires precise identification of pipe sizing before purchase
  • Limited to specific Class C and MDPE compatibility
  • Not intended for non-standard or irregular pipe diameters

Setup, Compatibility & Care

Installation should be performed by ensuring the pipe ends are cut square and are free from debris or jagged edges. Once the pipe is prepared, slide the components onto the pipe and tighten the mechanical coupler to the manufacturer's specified torque.

Care instructions include periodically inspecting joints for any signs of moisture or shifting after initial installation, particularly in ground-based systems subject to settling. Ensure the fitting is kept away from harsh chemical solvents that could degrade the integrity of the pipe material. Always confirm the specific MPN matches your existing system requirements before starting the work.
