Grommet - male thread - N - 15mm-R1/2" IVAR.IVN81

Product detailed description

Press fittings are essential components in modern plumbing and heating systems, particularly in applications where leak-free and durable connections are required. The IVAR IVN81.1512 is a male-threaded press fitting used to connect a 15mm press tube to a R1/2 thread. It is commonly used in residential and commercial buildings for heating systems, water supply lines, and industrial applications. The fitting is designed for use in environments where the system is exposed to a range of temperatures and pressures, making it suitable for both indoor and outdoor installations.

Installers working on central heating systems, solar installations, or industrial piping often encounter the need for reliable connections between press tubes and threaded components. The IVAR IVN81.1512 ensures compatibility between press and threaded systems, allowing for a secure and long-lasting connection. It is particularly useful in systems where flexibility and ease of installation are required, such as in retrofitting or where space is limited.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN81.1512
Brand	IVAR

The operating temperature range of -20°C to +85°C, with a maximum of +120°C, allows the fitting to be used in a wide range of environments, including cold water systems and heated applications. The PN16 rating indicates that it can handle pressures up to 16 bar at 20°C, which is typical for most domestic and commercial heating and plumbing systems. These parameters are essential for proper sizing and selection, ensuring the fitting meets the system's operational demands.

Installation and connection

To install the IVAR IVN81.1512, the press tool must be used to compress the fitting onto the 15mm press tube. The fitting is designed for use with a press tool that ensures the correct compression force is applied, creating a secure and leak-free connection. The male R1/2 thread is intended for connection to threaded components such as valves, meters, or other fittings. The O-ring must be properly seated in its groove to ensure a tight seal. Common installation mistakes include using the wrong size press tool, failing to check the O-ring for damage, or not ensuring the tube is fully inserted before pressing.

Compatibility and accessories

The IVAR IVN81.1512 is compatible with 15mm stainless steel press tubes and R1/2 male-threaded components. It is designed for use with EPDM O-rings and should be used in conjunction with press tools that are calibrated for 15mm tube sizes. No additional accessories are required for standard installation, but it is important to ensure that the press tool is correctly sized and maintained to avoid installation errors.

Technical background for designers

The IVAR IVN81.1512 operates on the principle of mechanical compression, where the press tool deforms the fitting around the press tube, creating a metal-to-metal seal. The use of 1.4404 stainless steel ensures high corrosion resistance, making it suitable for use in aggressive environments such as those found in industrial or chemical applications. The EPDM O-ring provides a secondary seal, ensuring that the connection remains watertight even under fluctuating pressure and temperature conditions. The integration of this fitting into a system depends on the system's pressure and temperature requirements, as well as the compatibility of the connected components.

Service and operation

No regular maintenance is required for the IVAR IVN81.1512 during normal operation. However, it is important to inspect the fitting periodically for signs of wear, corrosion, or leakage. If the fitting is part of a system that is exposed to high temperatures or aggressive media, it should be checked more frequently. The O-ring should be replaced if it shows signs of degradation, and the fitting should be repressed if there is any indication of a loose or damaged connection.

Frequently asked questions

Can the IVAR IVN81.1512 be used in solar heating systems?
Yes, the fitting is suitable for solar heating systems as it is rated for temperatures up to +120°C and can handle the pressure requirements of such systems.

Is the IVAR IVN81.1512 compatible with other IVAR press fittings?
Yes, the fitting is designed to work with other IVAR press fittings and components, ensuring system compatibility and ease of installation.

Can the fitting be used in industrial gas applications?
Yes, the fitting is suitable for inert gas applications due to its stainless steel construction and EPDM O-ring, which are resistant to most gases and vapours.

Can the IVAR IVN81.1512 be used with copper press tubes?
No, the fitting is specifically designed for use with stainless steel press tubes and should not be used with copper or other materials without confirmation from the manufacturer.
