No, it is a push-fit connector and does not require soldering tools or heat.

Troubleshooting

Check that the pipe diameter is exactly 28mm and ensure the end is cut square without excessive burrs.
Pros and Cons
Pros
- Significantly faster installation times compared to copper soldering
- No hot works permits or specialized welding equipment required
- Highly resistant to internal pressures and temperature fluctuations
- Certified to UK regulatory standards for plumbing infrastructure
Cons
- Restricted to 28mm pipe diameters
- Requires precise pipe cutting to ensure a watertight seal
- Cannot be used as a transition fitting for pipes of different materials without specific adapters
Setup, Compatibility & Care
To install, ensure the pipe end is cut square and free of any burrs or rough edges. It is highly recommended to deburr the cut end to avoid damaging the internal O-ring seal upon insertion. Simply push the pipe fully into the coupler until it hits the internal stop. For maintenance, avoid using aggressive chemical cleaners on the exterior. If a system needs to be disassembled, ensure the pressure is fully bled from the line before attempting to release the pipe. Always verify that the pipe is fully inserted to ensure the grab ring has engaged securely.
