T-piece press - reduced, 50 x 50 x 32

Product detailed description

The IVAR press T-piece with reduced dimensions is commonly used in residential and commercial buildings for the connection of ALPEX pipes in heating and plumbing systems. This fitting allows the branching of flow paths when different pipe diameters are involved, making it ideal for balancing and zoning applications in underfloor heating, radiators, or hot water circuits. Installers working with press tools and ALPEX piping will find this component essential for maintaining hydraulic performance and ensuring leak-free joints.

Typical installation scenarios include the integration of this T-piece into manifold systems, where it connects supply and return lines to individual heating loops. It is also used in secondary circuits such as heat exchangers or buffer tanks. The fitting is designed to handle medium temperatures and pressures typical of domestic and light commercial heating systems.

Brand	IVAR

The operating temperature limit of +120°C makes this fitting suitable for systems using glycol-based heat transfer fluids or high-temperature hot water. The PN 10 rating ensures compatibility with standard domestic and low-pressure commercial systems. The nickel-plated brass construction provides corrosion resistance and durability in wet environments.Installation and connection The fitting is designed for use with ALPEX pipes of different diameters. The nominal inlet and outlet sizes are 50 mm, while the branch size is 32 mm. All connections are made using a press tool compatible with B-F-TH jaw types. Prior to pressing, ensure the pipe ends are clean, free of burrs, and properly aligned with the fitting. The stainless steel sleeve should fully enclose the pipe wall during the pressing process to form a secure joint. Common installation errors include using incorrect jaw types, insufficient pipe insertion depth, or misalignment between the pipe and fitting. These can lead to weak joints or leaks. After pressing, the joint should be visually inspected for even deformation and correct sleeve position. Re-pressing is not recommended unless specified by the manufacturer’s guidelines.

Compatibility and accessories

This T-piece is specifically designed for use with ALPEX pipes and requires a compatible press tool with jaws of type B-F-TH. The EPDM sealing material is suitable for use with glycol solutions and potable water. Additional components such as straight press fittings, elbows, or couplings may be required depending on the system layout. No related products are available for this model.

Technical background for designers

The press T-piece operates by compressing the stainless steel sleeve around the pipe wall, forming a metal-to-metal seal supported by the EPDM gasket. The nickel-plated brass body offers high mechanical strength and resistance to corrosion, particularly in wet or humid environments. The CW617N alloy is known for its good machinability and dimensional stability under thermal cycling. The design allows for a compact layout in tight spaces due to the reduced dimensions of the branch. When integrated into a system, the fitting contributes to overall hydraulic balance and minimises pressure losses. Long-term performance depends on correct installation and compatibility with the system fluid and operating conditions.

Service and operation

Once installed, the T-piece requires no regular maintenance. However, periodic visual inspections are recommended to check for signs of leakage, corrosion, or mechanical stress. If the system is shut down for extended periods, it should be drained to prevent freezing damage. No specific service intervals are provided in the product documentation.

Frequently asked questions

Can this press T-piece be used with other types of pipe besides ALPEX?
No, it is specifically designed for ALPEX pipe systems and requires a compatible press tool for installation.

Is it possible to re-press the fitting after the initial pressing?
Re-pressing is generally not recommended unless the manufacturer explicitly states it is acceptable for this model.

What is the maximum allowable operating temperature for this fitting?
The fitting is rated for a maximum operating temperature of +120°C, suitable for most heating applications.

Does the nickel plating affect the sealing performance?
No, the nickel plating provides corrosion resistance but does not interfere with the sealing function of the EPDM gasket or the stainless steel sleeve.
