Product Information

Full details

The John Guest MDPE Compression Elbow is an essential component for professional plumbers and DIY installers working on cold water pipelines who need to achieve a secure 90-degree turn in restricted spaces. Its primary benefit is the tool-free, demountable design that ensures a watertight connection without the need for heat or complex installation equipment, though users should ensure their pipe ends are cut cleanly to maintain the integrity of the seal.

Extended Product Information

FAQs

Is this fitting suitable for hot water systems?

No, this specific model is designed for cold water supply pipelines only.

Do I need special tools to tighten the connection?

No, the compression mechanism is designed for tool-free, hand-tightened installation.

Can I reuse this elbow if I decide to change the layout?

Yes, because the fitting is demountable, it can be dismantled and reused, provided the components are undamaged.

Is this product compatible with PEX piping?

This fitting is specifically engineered for 20mm MDPE pipe; we recommend using it only with compatible MDPE material.

Is it safe for use in drinking water systems?

Yes, this component is WRAS approved, meaning it meets the necessary standards for potable water.

Troubleshooting

Water leakage at the connection point

Ensure the pipe end is cut square and is not scratched. Re-seat the pipe firmly into the fitting to confirm the O-ring seal is engaged.

Difficult to insert the pipe

Check the pipe end for burrs or deformation. A slight chamfer on the edge of the pipe can assist with smooth entry into the compression assembly.

Pros and Cons

Pros

  • Requires no heat or soldering for installation
  • Easy to adjust or remove if layout changes occur
  • Compact size fits well in tight, restricted trenches
  • WRAS approved for safe water supply use
  • Pre-assembled for immediate installation

Cons

  • Specific to 20mm MDPE pipe sizes only
  • Requires clean, square pipe cuts for a proper seal
  • Plastic construction may not withstand high-impact mechanical stress

Setup, Compatibility & Care

To ensure a successful installation, first ensure that the MDPE pipe end is cut perfectly square and is free of any burrs or debris. Insert the pipe firmly into the fitting until the compression ring engages. While the connection is tool-free, ensure the pipe is pushed fully home to guarantee a watertight seal. This elbow is strictly compatible with 20mm MDPE piping and is intended for cold water service lines. For care, keep the threads and O-ring surfaces clean during storage. If the fitting is buried, ensure the surrounding soil is free of large, jagged rocks that could put uneven pressure on the fitting housing.
