Plumbright 22mm Double Seal Insert White plastic NDSI22M

Plumbright Double Seal Pipe Insert

The Plumbright Double Seal Pipe Insert is fitted inside compatible plastic pipe before jointing. It supports the pipe wall at the connection point and helps the assembled push-fit joint maintain a secure, dependable seal.

Key Features and Benefits

• Supports the pipe bore at the joint to reduce the risk of distortion
• Double-seal design helps provide additional confidence at the connection
• Quick to fit during first-fix and final connection work
• A small but important component for consistent push-fit joint preparation

Suitable Applications and Compatibility

Designed for compatible plastic pipe systems and suitable hot and cold water or heating services. Compatibility with pipe, inserts and any connection to copper tube should be checked against the manufacturer's current instructions.

Role in Wet Underfloor Heating

Reliable joints are essential around heat sources, pumps, controls and manifolds. In a wet underfloor heating installation, the correct insert supports long-term system integrity and helps reduce the risk of leaks at accessible distribution connections.

Guidance

Cut the pipe squarely with a suitable pipe cutter, ensure the end is clean and undamaged, then push the insert fully home before assembling the fitting. Confirm the pipe is inserted to the required depth and pressure-test the completed system before it is concealed or commissioned.
