T-piece 42 x 28 x 42

Product detailed description

Reduced T-pieces are essential components in pressurised pipe systems, particularly in central heating, fire suppression and industrial applications. Installers commonly use them to create branch connections in closed systems where high-pressure resistance and reliable sealing are required. These fittings are frequently found in residential, commercial and industrial buildings, enabling efficient routing of fluids and gases through complex networks. The 90° angle allows for directional changes while maintaining system integrity.

When installing in central heating or refrigeration systems, the fitting must be selected based on the system’s pressure and temperature requirements. The fitting’s press connection design eliminates the need for threading or welding, reducing installation time and potential leak points. It is particularly useful in environments where system flexibility and rapid assembly are priorities. Proper alignment and secure pressing are critical to ensure long-term performance and safety.

The operating temperature range of -20°C to +120°C makes this fitting suitable for a wide variety of systems, including those with fluctuating thermal conditions. The maximum pressure rating of 16 bar ensures compatibility with high-pressure applications such as fire suppression systems. These parameters are crucial for correct sizing and system design, especially when integrating with other press components and ensuring long-term reliability.

Installation and connection

To install the T-piece, ensure that all connecting pipes are properly prepared with clean, burr-free ends. Use Type M jaws for pressing operations, and confirm that the molding indicator is fully engaged after pressing. The press tool should be calibrated to match the fitting’s specifications. Common installation errors include misalignment of the branches, insufficient pressing force, or using incorrect jaws. Always verify the fit with a visual inspection and test the system under pressure before commissioning to detect any potential leaks or weak points.

Compatibility and accessories

This T-piece is compatible with other IVAR press fittings and pipes within the same size range. For complete system integration, additional components such as straight couplings, elbows and valves may be required depending on the system layout. Ensure that all components are from the same press system to maintain uniformity and avoid compatibility issues during assembly and operation.

Technical background for designers

The T-piece operates on the principle of mechanical compression, where the EPDM O-ring forms a tight seal between the pipe and fitting. The carbon galvanized steel construction provides corrosion resistance and structural strength, making it suitable for both wet and dry environments. When integrated into a system, the fitting’s thermal expansion and contraction should be considered, especially in systems with significant temperature variations. The choice of press system and proper installation technique directly affect the component’s service life and overall system efficiency.

Service and operation

During regular system checks, inspect the T-piece for signs of wear, corrosion or leakage. No scheduled maintenance is required beyond these inspections. If a leak is detected, the affected section should be isolated and replaced. The absence of surface coatings means that the fitting relies on the inherent properties of the material for long-term durability. Always follow the manufacturer’s guidelines for troubleshooting and repair procedures.

Frequently asked questions

Can this T-piece be used in solar water heating systems?
Yes, provided the system operates within the specified temperature and pressure limits of -20°C to +120°C and up to 16 bar.

Is it compatible with inert gas systems?
Yes, the fitting is suitable for use with inert gases as long as the gas does not react with the EPDM O-ring or the steel material.

Can the T-piece be used in fire suppression systems?
Yes, it meets the necessary pressure and sealing requirements for permanently water-filled fire suppression systems.

Is it possible to combine this T-piece with other press systems?
Only if the other systems use the same press technology and jaw type (Type M) to ensure a secure connection.
