Elbow 90° - male thread, 15 x R 3/8

Product detailed description

This 90° elbow is commonly used in closed pressurized heating systems, fire water circuits, air conditioning installations and industrial piping. It facilitates directional changes in press pipe systems where a transition from press to threaded connections is required. Installers working in residential, commercial and industrial settings use this component to connect radiators, valves and other threaded devices to press pipe networks. The elbow is suitable for both new installations and system modifications, where compatibility with existing threaded fittings is necessary.

Its design allows for rapid, leak-free installation without the need for welding or threading. The elbow is supplied in a pack of 20 pieces, making it suitable for large-scale projects. It is particularly useful in systems where high-pressure resistance and a wide operating temperature range are required, such as in central heating, solar systems and industrial air or gas transport.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.082 kg
Code	IVC31.1538
Brand	IVAR

The elbow is rated for a nominal pressure of PN 16, meaning it can handle continuous operation at 16 bar. It is suitable for temperatures from -20 °C up to +85 °C, with a maximum short-term limit of +120 °C. These parameters are essential for selecting the component in systems with fluctuating thermal loads or high-pressure environments. The material and sealing properties ensure long-term integrity in pressurized systems.

Installation and connection

The elbow features a male R 3/8 thread on one end and a press connection on the other. To install, the press end is connected to a 15 mm press pipe using compatible Type M jaws. The threaded end is then screwed into the corresponding female fitting. It is important to ensure that the molding indicator is fully engaged and that the O-ring is correctly seated to prevent leaks. Common installation errors include using incorrect jaw types or failing to align the molding indicator, which can lead to compromised sealing.

Compatibility and accessories

This elbow is compatible with IVAR press pipe systems and standard R 3/8 threaded components. It is recommended to use it with IVAR press fittings and EPDM O-rings for optimal performance. No additional surface coating agents are required, as the elbow is designed for leak-free operation without them. When ordering, ensure that the correct Type M jaws are available for the press connection.

Technical background for designers

The elbow operates by allowing a directional change in the piping system while maintaining a secure connection between press and threaded components. The carbon galvanized steel construction provides resistance to corrosion and mechanical damage, while the EPDM O-ring ensures a tight seal. The elbow is suitable for use with water, dry air, inert gases and industrial media. The operating temperature range and pressure resistance are key factors in determining its suitability for specific applications. Long-term performance depends on correct installation and the absence of excessive mechanical stress or thermal cycling beyond the specified limits.

Service and operation

No regular maintenance is required for this component. However, during system inspections, it is advisable to check for signs of mechanical damage, corrosion or leakage around the press and threaded connections. If the molding indicator is not fully engaged or if the O-ring shows signs of wear, the component should be replaced. The elbow is not certified for drinking water applications and should not be used in such systems.

Frequently asked questions

Can the IVAR IVC31.1538 be used in solar heating systems?
Yes, it is suitable for solar systems provided the operating temperature does not exceed +120 °C and the pressure remains within the PN 16 rating.

Is it compatible with other press pipe systems besides IVAR?
It is specifically designed for IVAR press pipe systems. Using it with other systems may compromise the integrity of the connection.

Can this elbow be used with dry air or inert gases?
Yes, it is suitable for dry air and inert gases within the specified pressure and temperature range.

What should be checked after installation to ensure a leak-free connection?
After installation, ensure the molding indicator is fully engaged and that the threaded connection is tightened to the correct torque. A visual inspection for signs of misalignment or damage is also recommended.
