Turn piece PRESS, 20 x 16 x 20

Product detailed description

This press T-piece is commonly used in residential and commercial heating installations where branch connections are required. It allows for the integration of radiators, underfloor heating manifolds or other heating appliances into the distribution network. Installers working with ALPEX pipe systems will find this component essential when creating branch points in existing piping runs. The T-piece ensures a secure and leak-free connection, suitable for both new builds and system extensions.

The installation process is typically carried out during the rough-in phase of a heating system. It is frequently used in combination with other press fittings to create a fully welded network. The compact dimensions and standardised interface make it suitable for tight spaces and complex layouts. The fitting is also compatible with systems requiring a 40 mm spacing between outlets, making it ideal for radiator installations with standard mounting distances.

Technical parameters

Installation and connection

To install the press T-piece, the installer should first cut the ALPEX pipe to the required length and ensure the cut end is clean and free of burrs. The pipe is then inserted into the fitting until it reaches the stop mark. A press tool is used to apply the necessary force around the circumference of the fitting, forming a permanent mechanical and hydraulic seal. The press tool must be correctly aligned to avoid uneven deformation, which could compromise the connection.

• Always verify that the pipe diameter matches the fitting dimensions (20 x 16 x 20 mm).
• Use a calibrated press tool to ensure the correct pressure is applied.
• Check for visual signs of correct pressing, such as even deformation and no visible gaps.
• Avoid over-pressing, which can damage the fitting or the pipe.
• Ensure the fitting is fully seated against the adjacent components before final pressing.

Compatibility and accessories

This T-piece is specifically designed for use with ALPEX pipes of the specified dimensions. It requires the use of a press tool compatible with IVAR fittings. No additional sealing materials are needed due to the mechanical nature of the press connection. For larger installations, it is recommended to have a sufficient number of fittings and tools available to maintain workflow efficiency.

Technical background for designers

The press connection operates through mechanical deformation of the fitting’s outer sleeve, which creates a tight and durable bond with the pipe. The nickel-plated brass body provides resistance to corrosion and ensures long-term stability. The EPDM gasket supports the initial sealing before pressing and contributes to the overall integrity of the joint. The CW617N brass alloy offers good thermal conductivity and mechanical strength, making it suitable for use in hot water heating systems. The nominal pressure and temperature ratings must be considered when designing the system to ensure safe and efficient operation.

Service and operation

Once installed, the press T-piece requires minimal maintenance. Routine inspections should include checking for signs of leakage, particularly at joints and branch points. If any issues arise, the affected section must be cut out and replaced with a new fitting. Due to the permanent nature of the press connection, rework is not possible without cutting the pipe. There are no scheduled service intervals for this component under normal operating conditions.

Frequently asked questions

Can the IVAR press T-piece be used with copper pipes?
No, this fitting is specifically designed for use with ALPEX pipes. Using it with copper would require different tools and fittings.

Is it possible to reuse the fitting after pressing?
No, once the press tool has been applied, the fitting cannot be reused. A new fitting must be installed if the connection is to be modified or repaired.

What is the minimum spacing between fittings?
There is no specific minimum spacing required for this fitting. However, it is recommended to follow standard installation practices to allow for access and future maintenance.

How is the fitting secured during installation?
The fitting is secured by pressing the outer sleeve around the pipe using a calibrated press tool. This creates a permanent mechanical connection that does not rely on threaded or glued joints.
