Key Features and Benefits

• Push-fit technology enables quick, tool-free installation
• Creates a secure reducing connection between 15mm and 28mm pipework
• Suitable for hot and cold water systems and heating installations, including wet underfloor heating
• WRAS approved and manufactured to high industry standards
• Durable, corrosion-resistant construction for long-lasting performance
• Demountable and reusable for flexibility during installation and maintenance
• Secure locking indicator helps confirm correct installation

Suitable Applications and Compatibility

This stem coupler reducer is suitable for domestic and light commercial plumbing systems where a reliable transition between different pipe sizes is required. It is compatible with standard plastic and barrier pipe systems and is commonly used in heating distribution pipework, manifold connections, and wet underfloor heating systems where efficient flow control and neat routing are essential.

Role In Underfloor Heating

Within a wet underfloor heating system, reducing couplers are used to connect different pipe sizes between manifolds, distribution pipework, and heating circuits. This ensures consistent flow rates and helps maintain balanced heat output across multiple zones. Its push-fit design allows for quick installation in confined or difficult-to-access areas while maintaining a secure, leak-free connection.

Guidance

Ensure pipe ends are clean, cut square, and free from burrs before installation. Push the pipe fully into the fitting until it reaches the internal stop to achieve a secure seal. Always verify compatibility with the pipe system being used and follow standard installation practices for sealed heating systems.
