T-piece 22 x 28 x 22

Product detailed description

Reduced T-pieces are essential components in pressurised systems such as central heating, fire suppression, and industrial air or gas distribution. Installers and designers use these fittings to create branch connections in closed-loop systems where space constraints require a reduction in one branch. In residential and commercial buildings, these fittings are often found in boiler circuits, underfloor heating manifolds, and compressed air lines. The 90° geometry ensures directional flexibility, while the reduced branch allows for smaller-diameter piping to be integrated without compromising flow integrity.

The IVC44.222822 is suitable for applications involving cold water, refrigeration, fire water, and non-potable air or gas. Its compact dimensions and lightweight make it ideal for tight spaces and overhead installations. The EPDM sealing ring ensures a leak-tight connection even in fluctuating temperatures. The absence of surface coatings means it is compatible with standard press tools and does not interfere with system diagnostics such as leak detection or pressure testing.

The operating temperature range of -20 °C to +120 °C makes this T-piece suitable for both low-temperature refrigeration and high-temperature heating systems. The PN 16 rating indicates that it can handle sustained pressures up to 16 bar, which is suitable for most domestic and light industrial applications. The galvanized steel construction provides corrosion resistance in non-drinking water environments, though it is not certified for potable water use. These parameters are critical for determining the suitability of the fitting in specific system designs, especially when considering thermal expansion and pressure surges during operation.

Installation and connection

To install the T-piece, ensure that all connected pipes have been cut square and deburred. Apply a small amount of lubricant to the EPDM O-ring to ease insertion. Insert the pipe ends into the fitting until the molding indicator is reached. Confirm that the molding mark is visible and that the press tool engages fully. Use only Type M jaws to avoid deformation. Check that the branch connection is aligned correctly and that the fitting is seated firmly against the pipe flanges. A common mistake is not verifying the molding indicator after pressing, which can lead to weak or uneven connections. Always test the system for leaks after installation using a pressure test according to local standards.

Compatibility and accessories

This T-piece is compatible with IVAR press fittings of 22 mm, 28 mm and 22 mm. It is suitable for use with EPDM O-rings and standard press tools. For larger systems or where additional support is required, consider using IVAR press clamps or expansion joints. Ensure that all system components are from the same manufacturer to maintain system integrity and warranty conditions. When designing a system, account for the thermal expansion of the steel pipes and include expansion loops or compensators where necessary.

Technical background for designers

The IVC44.222822 operates on the principle of mechanical compression to create a leak-tight joint between the pipe and the fitting. The galvanized steel body provides structural strength and resistance to corrosion in non-drinking water environments. The EPDM O-ring is flexible enough to accommodate minor misalignments and thermal movement while maintaining a seal. The fitting integrates into pressurised systems by allowing the designer to reduce the diameter of one branch without introducing a threaded or welded joint. The service life of the fitting is influenced by the quality of the press operation, the frequency of pressure surges, and the presence of contaminants in the system fluid. Regular inspection of the press marks and O-ring condition can help prevent failures.

Service and operation

During operation, the T-piece requires no active maintenance. However, it should be visually inspected periodically for signs of corrosion, deformation, or leakage. Any damage to the press marks or O-ring should be addressed immediately by replacing the affected component. In systems with high particulate content, consider installing filters upstream of the fitting to prevent abrasive wear. No specific service intervals are provided in the technical documentation, but the system should be tested annually for leaks and pressure integrity.

Frequently asked questions

Can the IVC44.222822 be used in a fire suppression system?
Yes, the T-piece is suitable for fire water supply systems as long as the operating conditions remain within the specified pressure and temperature limits.

Is the T-piece compatible with copper pipes?
No, the T-piece is designed for use with steel pipes only. Using it with copper would require a different type of fitting or adapter.

Can the T-piece be used in a refrigeration system?
Yes, the operating temperature range includes down to -20 °C, making it suitable for refrigeration applications.

Is the T-piece suitable for outdoor installations?
It can be used outdoors if the system is pressurised and protected from direct exposure to weather elements such as rain and UV radiation.
