Elbow 90° - externally threaded, 18 x R 1/2

Product detailed description

This 90° elbow is commonly used in central heating systems, fire water piping, and industrial applications where a secure, leak-proof connection is required. It is suitable for closed pressurized systems and can be integrated into systems operating with dry air, inert gases, or water-based media. The elbow is designed for use with press-fit tools and is intended for installation without the need for welding or threading. It is particularly useful in applications where space constraints require directional changes in the piping layout.

Typical installation environments include residential and commercial buildings, industrial facilities, and solar system installations. The elbow is often used in conjunction with other press-fit components to create a robust and efficient piping network. Its compact design and ease of installation make it a preferred choice for professionals working in HVAC, plumbing, and fire protection sectors.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.132 kg
Code	IVC31.1812
Brand	IVAR

The elbow is rated for a nominal pressure of PN 16 and can withstand operating pressures up to 16 bar. It is suitable for temperatures ranging from -20 °C to +120 °C, making it adaptable to a wide range of environments. These parameters are essential for determining compatibility with system requirements and ensuring long-term performance under expected operating conditions.

Installation and connection

The elbow is installed using press-fit tools compatible with Type M jaws. The connection is made by inserting the pipe into the fitting until the molding indicator is engaged. It is important to ensure that the molding process is complete and that the indicator is visible to confirm a secure connection. The elbow has an external male thread (R 1/2) for connecting to threaded components. During installation, the installer should verify that the EPDM O-ring is properly seated and undamaged. Common mistakes include insufficient molding depth, incorrect tool calibration, and using incompatible tools, which can compromise the integrity of the joint.

Compatibility and accessories

This elbow is compatible with other IVAR press-fit components and can be used in systems that include pipes and fittings with diameters ranging from 15 mm to 108 mm. It is not certified for use with drinking water. For installation, press-fit tools of the correct size must be available. No additional sealing compounds or coatings are required, as the EPDM O-ring provides a sufficient seal when properly molded.

Technical background for designers

The elbow operates on the principle of mechanical compression, where the press-fit tool deforms the fitting to create a tight, leak-proof joint. The carbon galvanized steel construction provides resistance to corrosion and mechanical damage, while the EPDM O-ring ensures a durable seal. The elbow is designed to integrate into closed pressurized systems and can handle a range of media including water, dry air, and inert gases. The service life and efficiency of the component depend on proper installation, correct system pressure and temperature, and the absence of aggressive media that could degrade the materials over time.

Service and operation

The elbow requires no regular maintenance under normal operating conditions. However, it is important to periodically inspect the connection for signs of leakage, especially after installation or following system pressure changes. If any issues arise, the joint should be re-checked for correct molding depth and O-ring condition. No scheduled service intervals are specified for this component.

Frequently asked questions

Can this elbow be used in a solar water heating system?
Yes, it is suitable for solar system piping provided the operating temperature does not exceed +120 °C and the system is not used for drinking water.

Is it compatible with other press-fit systems besides IVAR?
It is specifically designed for use with IVAR press-fit components and may not be compatible with other systems without verification.

Can the elbow be used in fire suppression systems?
Yes, it is suitable for fire water piping as long as the system pressure and temperature remain within the specified limits.

Is it possible to install this elbow without a press-fit tool?
No, the elbow requires a press-fit tool compatible with Type M jaws to ensure a secure and leak-proof connection.
