Socket - sliding - N - 108mm IVAR.IVN11

Product detailed description

Sliding sockets are essential components in press-fit stainless steel pipe systems, particularly in heating and plumbing applications where flexibility and durability are required. These fittings are commonly used in residential and commercial buildings, including industrial facilities, for systems such as heating, water supply, fire sprinklers and solar installations. Installers often encounter these fittings in environments where thermal expansion and contraction are significant, such as in underfloor heating systems or in high-temperature applications like steam or hot water distribution. The sliding design allows for axial movement without compromising the integrity of the connection, making it ideal for long pipe runs or where alignment adjustments are necessary during installation.

Proper selection and installation of sliding sockets are critical to ensuring the long-term performance of the system. The fitting must be compatible with the pipe size and material, and the installation process must be followed precisely to avoid leaks or mechanical failure. The operating conditions, including temperature and pressure, must also be considered to ensure the fitting performs as intended over its service life.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN11.108
Brand	IVAR

The technical parameters of the IVAR IVN11.108 are essential for correct sizing and system compatibility. The operating temperature range from -20 °C to +120 °C allows the fitting to be used in a wide range of environments, from cold water supply to hot water and heating systems. The nominal pressure rating of PN 16 indicates that the fitting is suitable for systems operating at up to 16 bar. These parameters are crucial for ensuring the fitting can withstand the mechanical and thermal stresses of the application without failure.

Installation and connection

The IVAR IVN11.108 is installed using a press-fit method, which requires a compatible press tool to compress the fitting onto the pipe. The fitting is designed for stainless steel pipes and must be used with the correct pipe diameter and wall thickness. The external thread allows for connection to other components such as valves or meters. During installation, the installer must ensure the pipe is clean and free of burrs before inserting it into the fitting. The press tool must be applied evenly to avoid misalignment or damage to the O-ring. A common mistake is not verifying the correct press depth, which can lead to leaks or mechanical failure. The fitting must also be checked for proper seating and alignment after installation to ensure a secure connection.

Compatibility and accessories

The IVAR IVN11.108 is compatible with stainless steel pipes of the appropriate diameter and wall thickness. It is typically used in conjunction with other press-fit fittings such as elbows, tees and couplings. The external thread allows for connection to threaded components, making it suitable for use in systems requiring a mix of press-fit and threaded connections. No additional accessories are required for standard installation, but the press tool must be compatible with the fitting's design. Installers should ensure that all components in the system are from the same manufacturer or are certified for use together to avoid compatibility issues.

Technical background for designers

Sliding sockets operate by allowing axial movement between the pipe and the fitting while maintaining a sealed connection. The EPDM O-ring ensures a tight seal and is resistant to a broad range of temperatures and media. The press-fit method relies on the deformation of the fitting to create a secure and leak-tight connection. The material properties of the stainless steel and the design of the fitting are critical to its performance, particularly in high-pressure and high-temperature applications. Designers must consider the thermal expansion of the system and the need for movement accommodation when specifying sliding sockets.

Service and operation

Once installed, the IVAR IVN11.108 requires minimal maintenance. The press-fit connection is designed to be permanent and does not require regular servicing. However, periodic visual inspections are recommended to check for signs of wear, corrosion or leakage. If a leak is detected, the fitting must be replaced, as the press-fit method cannot be re-used. The system should also be checked for proper alignment and movement accommodation to prevent mechanical stress on the fitting. No specific service intervals are required for this fitting, but it should be inspected during routine system maintenance.

Frequently asked questions

Can the IVAR IVN11.108 be used with copper pipes?
No, the fitting is specifically designed for stainless steel pipes and is not compatible with copper.

Is the fitting suitable for steam systems?
Yes, the operating temperature range includes up to +120 °C, which is suitable for steam and hot water systems.

Can the fitting be used in outdoor applications?
Yes, provided the system is protected from direct exposure to the elements and the operating conditions remain within the specified parameters.

What is the maximum pressure the fitting can handle?
The nominal pressure rating is PN 16, which means it can handle up to 16 bar of pressure.
