Grommet - male thread - N - 15mm-R3/8" IVAR.IVN81

Product detailed description

Press-to-thread adapters are essential components in modern heating, plumbing and industrial systems where a secure and durable connection between press fittings and threaded components is required. This type of connection is commonly used in residential and commercial buildings, particularly in central heating systems, solar installations, and pressurised air systems. The IVAR IVN81.1538 is specifically designed for use in environments where resistance to corrosion and thermal expansion is critical. It ensures a tight and leak-free connection between a 15mm press fitting and a R3/8 male thread, making it suitable for a range of installation scenarios where compatibility between different connection types is necessary.

During installation, the adapter is pressed into the corresponding press fitting using a calibrated pressing tool. The pressing process must be carried out with precision to ensure the correct seating of the O-ring and the full engagement of the press collar. The final step involves verifying the press mark and the indicator to confirm a successful connection. Any deviation from the specified procedure may result in a compromised seal or mechanical integrity.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN81.1538
Brand	IVAR

The nominal pressure rating of PN 16 indicates the maximum pressure the adapter can withstand under normal operating conditions. The temperature range of -20°C to +85°C, with a maximum of +120°C, defines the thermal limits within which the material and sealing properties remain stable. These parameters are essential for determining the suitability of the adapter in different system configurations and for ensuring long-term reliability in service.

Installation and connection

The installation process involves aligning the adapter with the press fitting and using a pressing tool to compress the collar around the tube. The connection size is 15mm on the press side and R3/8 on the threaded side. It is important to ensure that the pressing tool is correctly calibrated and that the press mark reaches the specified depth of 54 mm. Common installation errors include insufficient pressing, misalignment of the components, and failure to check the press indicator. These can lead to leaks or mechanical failure under pressure.

Compatibility and accessories

This adapter is compatible with standard 15mm press fittings and R3/8 male-threaded components. It is typically used in conjunction with stainless steel pipes and press tools suitable for 1.4404 stainless steel. No additional accessories are required for basic installation, but a pressing tool and measuring device are essential for proper fitting. Related products include press fittings, stainless steel pipes, and pressing tools from the IVAR range.

Technical background for designers

The adapter functions by creating a mechanical and hydraulic seal between the press fitting and the threaded component. The use of 1.4404 stainless steel ensures resistance to corrosion and thermal expansion, making it suitable for both hot and cold media. The EPDM sealing ring provides flexibility and maintains a tight seal under varying pressure and temperature conditions. The integration of the adapter into a system depends on the system's pressure and temperature requirements, as well as the compatibility of the connected components. The service life of the adapter is influenced by the quality of the pressing process, the stability of the system conditions, and the absence of mechanical stress on the connection.

Service and operation

No specific service intervals are required for this component. However, during routine system checks, it is advisable to inspect the press mark and the integrity of the connection for any signs of wear or leakage. If a leak is detected, the connection should be disassembled and re-pressed using the correct procedure. The EPDM sealing ring should be replaced if it shows signs of degradation due to prolonged exposure to high temperatures or chemical media.
