T-piece, 1/2" FFF

Product detailed description

This T-piece is commonly used in residential and commercial heating and plumbing systems to create a branch connection in a pipe run. It is suitable for applications such as underfloor heating, domestic hot water distribution, and central heating circuits. The nickel-plated brass construction ensures resistance to corrosion and wear, making it ideal for long-term use in systems with circulating water or glycol-based heat transfer fluids. Installers should ensure that the fitting is compatible with the system pressure and temperature requirements before installation.

When installing this T-piece, it is important to consider the alignment of the branch connection and the main pipe run. The fitting is designed for use with standard pipe sizes and thread types, ensuring a secure and leak-free connection. It is commonly used in conjunction with other threaded fittings, valves, and pipe sections to create a complete system layout. The PN 10 rating indicates that the fitting is suitable for systems operating at a nominal pressure of 10 bar, making it suitable for most low- to medium-pressure applications.

Technical parameters

Installation and connection

The T-piece is designed for use with 1/2 inch internal threads on all three ports. Before installation, ensure that the threads are clean and free from debris. Apply a suitable thread sealant or PTFE tape to the male threads to ensure a watertight connection. Tighten the fitting using a wrench or spanner, taking care not to overtighten and damage the threads. A common mistake is to install the fitting without proper sealing, which can lead to leaks. Another error is misalignment of the branch port, which can cause flow restrictions or stress on the system.

Compatibility and accessories

This T-piece is compatible with standard copper and steel pipes that use 1/2 inch internal threads. It can be used in conjunction with other IVAR threaded fittings, such as elbows, couplings, and valves, to create a complete piping system. For larger systems, it may be necessary to use additional fittings or support brackets to maintain alignment and prevent vibration. No specific accessories are required for installation, but a thread sealing compound or PTFE tape is recommended to ensure a secure connection.

Technical background for designers

The T-piece operates by allowing the flow of fluid to be divided into two branches or combined from two sources. The nickel-plated brass CW617N material provides good mechanical strength and resistance to corrosion, making it suitable for use in both closed and open systems. The PN 10 rating ensures that the fitting can handle the pressure fluctuations commonly encountered in heating and plumbing systems. The operating temperature of +120°C is suitable for most heating applications, including those involving glycol-based heat transfer fluids. The design of the fitting allows for smooth flow with minimal turbulence, which helps to maintain system efficiency and reduce energy consumption.

Service and operation

Regular inspection of the T-piece is recommended to ensure that the connection remains secure and leak-free. Check for signs of corrosion, wear, or leakage, especially at the thread connections. If any issues are detected, the fitting should be replaced immediately. No specific service intervals are provided for this product, but it is advisable to inspect the fitting during routine system maintenance. In the event of a leak, the system should be depressurised and the fitting removed for inspection or replacement.

Frequently asked questions

Can the IVAR RF 820 N T-piece be used in a glycol-based heating system?
Yes, the T-piece is suitable for use in systems with glycol-based heat transfer fluids, provided that the operating temperature does not exceed +120°C and the pressure remains within the PN 10 rating.

Is the T-piece compatible with copper and steel pipes?
Yes, the fitting is compatible with both copper and steel pipes that use 1/2 inch internal threads. It is important to ensure that the threads are clean and properly sealed during installation.

What is the maximum operating temperature for this T-piece?
The maximum operating temperature is +120°C. Exceeding this temperature may compromise the integrity of the fitting and lead to failure.

Can this T-piece be used in a high-pressure system?
No, the fitting is rated for a nominal pressure of PN 10. It is not suitable for systems operating at higher pressures, as this may result in leaks or failure of the connection.
