T-piece - 4 "x4 "x4" IVAR.1570 G

Product detailed description

This T-piece is commonly used in residential and commercial building services for connecting three pipe runs in a branch configuration. It is suitable for installation in central heating systems, domestic hot and cold water circuits, and industrial process piping where reliable branch connections are required. The fitting is typically used by plumbers, heating engineers and service technicians during new installations or system upgrades.

The component is intended for use with threaded steel or copper pipes, ensuring secure and leak-free connections. Due to its material and pressure rating, it is suitable for low-pressure hydraulic circuits with moderate temperatures. The dimensions and thread configuration make it compatible with standard 4-inch piping systems.

Technical parameters

Installation and connection

Installation involves aligning the T-piece with the three connected pipe runs and tightening the threaded joints using a suitable wrench. Ensure that the male threads are clean and free from burrs before assembly. Apply a sealing compound or PTFE tape to the threads to prevent leaks. Check that all connections are tightened evenly to avoid stress on the fitting body. Common installation errors include cross-threading and over-tightening, which can damage the threads or cause leakage.

Compatibility and accessories

This T-piece is compatible with standard 4-inch threaded steel and copper pipes. It is typically used with sealing compounds, PTFE tape or rubber gaskets to ensure a watertight seal. For complete system integration, additional fittings such as elbows, couplings and valves may be required depending on the layout of the installation. No specific accessories are required beyond standard installation materials.

Technical background for designers

The operating principle of the T-piece is based on its ability to provide a branch connection between three pipe lines. The material, CW617N brass, offers good corrosion resistance and mechanical strength, making it suitable for long-term use in water and heating systems. The fitting integrates into the system by providing a stable connection point that maintains flow integrity. The service life and efficiency are influenced by the quality of the installation, the cleanliness of the system and the absence of excessive vibration or thermal cycling.

Service and operation

Regular visual inspections should be carried out to check for signs of leakage, corrosion or mechanical damage. Any tightness issues can often be resolved by resealing the threaded connections. There are no specific service intervals required for this component as it is a passive fitting with no moving parts. In the event of a leak, the entire section should be isolated and the affected connection inspected and resealed or replaced.

Frequently asked questions

Can the T-piece be used in potable water systems?
Yes, the fitting is approved for use with drinking water under ATEST certification.

What type of sealing material is recommended for the threads?
PTFE tape or a water-based sealing compound is suitable for ensuring a leak-free connection.

Is the T-piece suitable for use in steam systems?
No, the operating temperature limit of +120°C means it is not suitable for steam applications.

Can the T-piece be used with copper pipes?
Yes, provided the copper pipe ends are threaded to match the fitting’s specifications.
