Pipe cap - N - 15mm IVAR.IVN50

Product detailed description

Sealing pipe ends is a critical task in the installation and maintenance of heating, plumbing and industrial systems. Whether working on residential, commercial or industrial projects, installers regularly need to seal unused pipe ends to prevent contamination, pressure loss or system failure. This stainless steel pipe cap is specifically designed for press-fit connections in systems such as sanitary installations, fire sprinklers, heating circuits, compressed air lines and solar systems. It ensures a secure and leak-free seal when properly installed, and is suitable for both temporary and permanent sealing applications.

Correct sealing is essential to maintain system integrity and prevent issues such as corrosion, contamination or pressure instability. This cap is designed for use with 15mm nominal diameter pipes and must be installed according to the manufacturer's specifications to ensure a reliable connection. It is not suitable for use in open systems or where dynamic pressure fluctuations are expected without additional checks.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN50.15
Brand	IVAR

The nominal pressure rating of PN16 indicates that the cap can withstand a maximum working pressure of 16 bar at reference temperature. The operating temperature range from -20°C to +120°C allows for use in both cold and hot water systems. These parameters are essential for correct sizing and selection to ensure the cap meets the requirements of the specific installation environment and system conditions.Installation and connection The IVN50.15 is installed using a press-fit method, which requires a compatible press tool and die set. The cap is placed over the pipe end and pressed into position according to the manufacturer's recommended depth. The EPDM O-ring ensures a tight seal when compressed during installation. It is important to verify that the pipe end is clean, free of burrs and within the correct dimensional tolerance before installation. A common mistake is insufficient pressing depth, which can lead to leaks or an unstable connection. Always check the press tool settings and ensure the indicator mark on the cap is fully engaged to confirm correct installation.

Compatibility and accessories

This pipe cap is compatible with standard press-fit stainless steel piping systems. It is designed for use with 15mm nominal diameter pipes and requires a compatible press tool for installation. No additional accessories are required for basic installation, but a suitable press tool and die set must be available. For larger systems or complex installations, additional sealing components or tools may be necessary depending on the application.

Technical background for designers

The cap functions by sealing the end of a pipe using a press-fit connection, which relies on mechanical deformation to create a tight seal. The stainless steel body provides corrosion resistance and mechanical strength, while the EPDM O-ring ensures a flexible and durable seal. The material properties of 1.4404 (AISI 316L) stainless steel make it suitable for a wide range of media, including water, air and inert gases. The integration into the system depends on correct installation depth and alignment with the pipe. The service life and efficiency of the cap are influenced by the quality of the press-fit connection, the condition of the pipe end and the operating conditions of the system.

Service and operation

The cap is designed for long-term use and requires no regular maintenance under normal operating conditions. However, it is important to periodically inspect the connection for signs of leakage, corrosion or mechanical damage. If the system is shut down for an extended period, it is recommended to check the integrity of the seal before resuming operation. No specific service intervals are required, but any visible damage or signs of wear should be addressed immediately to prevent system failure.

Frequently asked questions

Can the IVN50.15 be used in solar heating systems?
Yes, the cap is suitable for solar heating systems as it can withstand operating temperatures up to +120°C and is compatible with the media typically used in such systems.

Is the cap suitable for use with compressed air systems?
Yes, the cap is appropriate for compressed air systems as it is designed for nominal pressure PN16 and can handle the typical pressure and temperature conditions in such applications.

Can the cap be used in open systems?
No, the cap is not recommended for use in open systems as it is designed for pressurised applications and may not provide an adequate seal in non-pressurised environments.

What should be done if the cap does not seal properly after installation?
If the cap does not seal properly, it is likely that the pressing depth was insufficient or the pipe end was not prepared correctly. The cap should be removed and reinstalled using the correct procedure to ensure a secure connection.
