T-piece 28 x 15 x 28

Product detailed description

Reduced T-pieces are commonly used in closed pressurised systems such as central heating, fire water supply, and industrial air or gas distribution. Installers and technicians working in commercial and industrial buildings often use these fittings to create branch connections in ductwork. The IVAR IVC41.281528 is suitable for applications involving dry air, inert gases, and water-based systems. It is particularly useful in environments where high-pressure resistance and a wide operating temperature range are required.

These fittings are often found in HVAC ducting, refrigeration systems, and solar system piping. The press-to-fit connection method eliminates the need for welding or threading, reducing installation time and ensuring a secure, leak-free joint. The compact design and low weight make it ideal for tight spaces and overhead installations.

Technical parameters

Installation and connection

Installation involves pressing the fitting onto prepared pipe ends using compatible Type M jaws. The connection sizes are 28 mm, 15 mm, and 28 mm. It is important to ensure the pipe ends are clean and free from burrs before pressing. Common installation mistakes include using incorrect jaw types or failing to check the molding indicator. The molding indicator must be fully engaged to confirm a secure connection.

Compatibility and accessories

This T-piece is compatible with other IVAR press-fit components and EPDM O-rings. For complete system integration, installers may need to order additional fittings, pipe sections, and pressing tools. It is not recommended for use with drinking water systems, as the material is not certified for potable water applications.

Technical background for designers

The fitting operates using a mechanical press-fit connection that relies on the deformation of the pipe wall to create a seal. The carbon galvanized steel construction provides resistance to corrosion and mechanical damage. The EPDM O-ring ensures a tight seal against media such as water, air, and inert gases. The material properties allow it to function effectively in both low-temperature and high-temperature environments. The system integration is simplified by the absence of threads or welding, which reduces the risk of leaks and installation errors.

Service and operation

Regular visual inspections should be carried out to check for signs of wear, deformation, or leakage. The molding indicator should be verified to ensure the connection remains intact. No specific service intervals are provided, but any damage or suspected failure should be addressed immediately to prevent system downtime.
