Adapter

Brass Adapter for Manifold Systems | 3/4” Eurocone to PEX 1216 / 1620 Compression Fitting

The brass adapter (Eurocone type) is a specialized connection fitting designed for underfloor heating manifolds and hydronic distribution systems. It is used at the bottom outlet of manifold assemblies to connect main manifold ports to PEX or PERT pipes, ensuring a secure and leak-free transition between threaded and plastic piping systems.

This adapter is widely applied in modern radiant floor heating installations where reliable sealing, easy installation, and compatibility with different pipe standards are required.

Available Sizes

This model is designed for two common PEX pipe specifications:

• 3/4” × 1216 (suitable for 12×1.6 mm PEX pipe)

• 3/4” × 1620 (suitable for 16×2.0 mm PEX pipe)

The 3/4” threaded end connects directly to standard manifold outlets, while the compression side fits PEX tubing securely.

Technical Specifications

• Material: Brass (typically Hpb59-1 or equivalent high-grade brass)

• Connection type: Eurocone compression fitting

• Thread size: 3/4” female connection

• Compatible pipe: PEX / PERT

• Working pressure: up to 1.6 MPa

• Temperature range: -10°C to 120°C

⚙️ Product Structure Advantages

This adapter features a precision-engineered compression system designed for long-term stability in heating environments:

• Multi-O-ring sealing structure for enhanced leak protection

• Split compression ring for firm pipe grip

• Precision machined nut for stable tightening torque

• Corrosion-resistant brass body for long service life

The design ensures that even under thermal expansion and continuous water circulation, the connection remains tight and secure.

Application Areas

The brass manifold adapter is commonly used in:

• Underfloor heating distribution manifolds

• Radiant heating system pipe connections

• HVAC hydronic distribution networks

• Residential and commercial water heating systems

It is especially suitable for systems requiring frequent maintenance or modular pipe replacement.

Key Benefits

• Fast and tool-friendly installation

• Strong sealing performance under pressure

• Compatible with European standard manifold systems

• Long-term resistance to corrosion and scaling

• Stable performance in hot and cold water environments

Summary

The 3/4” × 1216 / 1620 brass adapter is an essential component in modern heating manifold systems, providing a reliable bridge between metal manifolds and plastic pipe networks. Its robust structure and standardized design make it a widely used solution in both residential and commercial hydronic installations.
