T-piece 35 x 28 x 35

Product detailed description

This reduced T-piece is commonly used in closed heating systems, fire suppression systems, and industrial piping. It is suitable for applications involving pressurised water, dry air, inert gases and other non-drinking water media. The fitting is typically installed in central heating ductwork, cold water and refrigeration systems, and air-conditioning systems. It is also used in solar system piping and fire water supply systems. The compact design and lightweight construction make it ideal for tight spaces and complex layouts where multiple branch connections are required.

The T-piece is designed for use in pressurised systems and is compatible with press-to-connect installation methods. It is not certified for potable water applications. The fitting is intended for use in closed systems where high pressure resistance and a wide temperature range are required. The EPDM O-ring ensures a tight seal and is compatible with Type M jaws for installation.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.178 kg
Code	IVC41.352835
Brand	IVAR

The operating temperature range from -20°C to +120°C makes this fitting suitable for both cold and hot media applications. The PN 16 rating indicates it can withstand pressures up to 16 bar, which is essential for high-pressure systems. The carbon galvanized steel construction provides durability and resistance to mechanical damage, making it suitable for industrial and commercial environments.

Installation and connection

The T-piece is installed using press-to-connect tools compatible with Type M jaws. The connection sizes are 35 mm, 28 mm and 35 mm, and all connections are press-fit. During installation, it is important to ensure the molding indicator is fully engaged and that the fitting is aligned correctly with the pipe. Common installation mistakes include using incorrect tools, failing to check the molding indicator, or applying excessive force during pressing. After installation, the system should be tested for leaks and the molding indicator should be visually inspected to confirm a secure connection.

Compatibility and accessories

This T-piece is compatible with other press-fit fittings and pipes from the IVAR IVC41 and IVC44 series. It is designed for use with EPDM O-rings and Type M jaws. No additional surface coating or limiting agents are required. For systems requiring larger diameters, fittings up to 108 mm are available in the same series. When installing, ensure that all components are from the same system to maintain compatibility and system integrity.

Technical background for designers

The T-piece operates by creating a branch connection in a pressurised system. The carbon galvanized steel body provides strength and resistance to corrosion, while the EPDM O-ring ensures a tight seal. The press-to-connect method eliminates the need for welding or threading, reducing installation time and risk of leaks. The wide operating temperature range and high-pressure resistance make it suitable for a variety of applications, including heating, fire suppression and industrial systems. The material properties and design allow for long-term performance in demanding environments.

Service and operation

The T-piece requires minimal maintenance due to its durable construction and press-fit design. There are no service intervals specified, but regular visual inspections are recommended to check for signs of wear, corrosion or leakage. During operation, ensure that the system pressure does not exceed 16 bar and that the temperature remains within the specified range. If any issues arise, the fitting should be replaced to maintain system integrity and safety.
