T-piece 76,1 x Rp 3/4 x 76,1

Product detailed description

This 90° T-piece is commonly used in closed pressurised systems for central heating, fire water supply, air-conditioning and industrial piping. It is designed for use in environments where high pressure resistance and a wide temperature range are required. The fitting is suitable for installation in residential, commercial and industrial buildings where reliable and leak-free connections are essential. The fitting is particularly useful in systems where permanent water presence is expected, such as sprinkler systems or refrigeration ductwork.

Its carbon galvanized steel construction provides resistance to mechanical damage and ensures long-term durability in pressurised environments. The EPDM O-ring ensures a tight seal and compatibility with a range of media, including dry air, inert gases and non-potable water. The fitting is not certified for drinking water applications and should not be used in such systems.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.994 kg
Code	IVC42.7634
Brand	IVAR

The operating temperature range from -20 °C to +120 °C allows the fitting to be used in both cold and hot environments, making it suitable for a wide range of applications. The PN 16 rating means it can handle pressures up to 16 bar, which is essential for high-pressure systems such as fire water supply or industrial air-conditioning ducts. These parameters are critical for correct sizing and selection to ensure the fitting performs reliably under the intended operating conditions.

Installation and connection

To install the T-piece, ensure the connecting pipes are clean and free from debris. The internal thread (Rp 3/4) must be matched with a compatible male thread on the pipe or fitting. Use a torque wrench to tighten the connection according to the manufacturer's specifications to avoid over-tightening, which can damage the EPDM O-ring and cause leaks. Check the molding indicator on the fitting to confirm a secure connection. Common installation mistakes include using incorrect thread types or failing to align the molding indicator properly, which can lead to poor sealing and system inefficiency.

Compatibility and accessories

This T-piece is compatible with Type M jaws for press fitting. It is designed for use with carbon galvanized steel pipes and EPDM O-rings. When installing, ensure that all components are from the same system to maintain compatibility and sealing performance. Additional components such as press tools, sealing rings and pipe sections may be required depending on the system configuration. No related products are available for this model.

Technical background for designers

The T-piece functions as a branch connection in pressurised piping systems. It is constructed from carbon galvanized steel, which offers high strength and resistance to corrosion in non-potable water and industrial media. The EPDM O-ring provides a flexible and durable seal, ensuring long-term performance in fluctuating temperature and pressure conditions. The fitting is designed to integrate into closed systems where mechanical stress and thermal expansion are factors. The service life and efficiency of the fitting depend on correct installation, use of compatible materials and adherence to operating limits such as temperature and pressure ratings.

Service and operation

Regular inspection of the connection for leaks and wear is recommended. Check the molding indicator after installation to confirm a secure fit. No specific service intervals are provided in the technical data. If a leak is detected, the fitting should be replaced immediately. Avoid using solvents or aggressive cleaning agents on the fitting, as they may degrade the EPDM O-ring. Ensure that the system is depressurised before performing any maintenance.
