T-piece press - reduced, 20 x 26 x 20

Product detailed description

This press T-piece is commonly used in residential and commercial buildings for connecting pipes in central heating, domestic hot water and plumbing systems. It enables the branching of piping systems while maintaining hydraulic balance and system integrity. The fitting is specifically intended for ALPEX pipe connections, allowing for a secure and leak-free junction between different pipe diameters. Installers should ensure correct alignment and even pressing of the fitting during installation to avoid misalignment or distortion.

Typical applications include underfloor heating circuits, expansion joints, and manifold connections. The fitting supports systems operating at nominal pressure PN 10 and can withstand continuous temperatures up to +120°C. It is especially suited for installations where space constraints require compact fittings and multiple branch points.

Technical parameters

The operating temperature limit of +120°C allows the fitting to handle hot water and heating circuits. The PN 10 rating indicates suitability for standard domestic and low-pressure industrial systems. The material combination ensures resistance to corrosion and mechanical stress under normal operating conditions.

Installation and connection

To install the press T-piece, ensure the ends of the ALPEX pipes are cut square and free of burrs. Insert the pipes into the corresponding ports of the T-piece until they reach the stop mark. Use a stainless steel sleeve over the joint area before applying pressure with a calibrated press tool. Ensure the tool is aligned perpendicular to the pipe axis to avoid ovalisation of the tube. After pressing, verify the joint with a go/no-go gauge to confirm proper engagement. Common errors include using mismatched sleeves, incorrect pressing force, or failing to align the press tool correctly.

Compatibility and accessories

This fitting is compatible with ALPEX copper-aluminium composite pipes. It requires the use of a stainless steel sleeve and EPDM sealing ring to ensure a watertight connection. When installing multiple press fittings, ensure all tools and sleeves are from the same manufacturer to maintain consistency. No related products are specified for this item.

Technical background for designers

The press mechanism relies on plastic deformation of the outer copper layer of the ALPEX pipe to form a mechanical bond with the nickel-plated brass body of the fitting. The CW617N brass alloy provides high tensile strength and wear resistance. The EPDM seal compensates for minor dimensional variations and prevents leakage. For long-term performance, ensure the system operates within the specified temperature and pressure limits. Avoid subjecting the fitting to repeated thermal cycling beyond the rated range.

Service and operation

No routine maintenance is required for press fittings under normal operating conditions. Regular checks should focus on verifying the absence of leaks and ensuring that the system operates within design parameters. In case of suspected damage or failure, the affected fitting should be replaced in accordance with the manufacturer’s guidelines. No specific service intervals are provided for this component.

Frequently asked questions

Can this T-piece be used to connect different types of pipe?
Only with ALPEX copper-aluminium composite pipes. Mismatched pipe materials may compromise the integrity of the connection.

Is the stainless steel sleeve included with the fitting?
The sleeve is not supplied with the fitting and must be obtained separately to complete the installation.

What happens if the press tool is not properly aligned during installation?
Improper alignment can lead to uneven pressing, which increases the risk of leaks or joint failure under pressure.

Can the fitting be reused after removal?
No. Once pressed, the fitting cannot be reused and must be replaced with a new unit to ensure a reliable connection.
