Connection fitting - externally threaded - N - 42mm-R6/4" IVAR.IVN64

Product detailed description

Stainless steel press-to-tap fittings are essential components in modern heating and plumbing installations where reliable and durable connections are required. These fittings are commonly used in residential and commercial buildings for connecting pipes to valves, radiators, and other system components. Installers working on heating systems, sanitary installations, and industrial piping frequently encounter situations where a secure and leak-free connection between a press pipe and an externally threaded component is necessary.

The IVAR IVN64.4216 is specifically designed for such applications. It ensures a tight and long-lasting seal between the press pipe and the threaded component. This fitting is particularly useful in systems where temperature fluctuations and varying pressures are common, such as in underfloor heating, solar thermal systems, and industrial process lines. The fitting is also suitable for fire suppression systems and compressed air applications, where system integrity is critical.

Technical parameters

The operating temperature range of -20°C to +85°C allows the fitting to function in a wide range of environments, including cold storage facilities and hot water systems. The maximum temperature of +120°C indicates the upper limit for short-term exposure. The PN16 pressure rating means the fitting can handle nominal pressures up to 16 bar, making it suitable for most low to medium-pressure systems. These parameters are crucial for selecting the correct fitting for the intended application and ensuring system reliability.

Installation and connection

To install the IVAR IVN64.4216, the press pipe must be prepared with the correct 42mm diameter and a clean, smooth surface. The fitting is then placed over the pipe end, ensuring the press ring is seated correctly. A press tool is used to compress the fitting onto the pipe, forming a secure and leak-proof connection. The external R6/4' thread must be cleaned and checked for damage before screwing the fitting into the corresponding component.

• Ensure the pipe end is cut square and free from burrs or debris.
• Verify the press tool is set to the correct size and pressure settings for 42mm pipe.
• Check that the sealing O-ring is properly seated and undamaged before pressing.
• After installation, inspect the fitting for signs of improper compression or misalignment.
• Avoid over-tightening the external thread to prevent damage to the fitting or the connected component.

Compatibility and accessories

The IVAR IVN64.4216 is compatible with standard 42mm stainless steel press pipes and components with R6/4' external threads. It is typically used in conjunction with other stainless steel fittings and valves in the same system. When installing, ensure all components are from the same manufacturer and system design to maintain compatibility and performance. Additional components such as valves, unions, and expansion joints may be required depending on the specific application and system design.

Technical background for designers

This fitting operates by forming a mechanical and hydraulic seal between the press pipe and the fitting body through the use of a high-strength stainless steel press ring and an EPDM O-ring. The EPDM O-ring ensures a flexible and durable seal that can accommodate minor pipe movements and thermal expansion. Proper system design should account for these properties to maximise the fitting’s service life and efficiency.

Service and operation

Regular inspection of the fitting during routine system maintenance is recommended to detect any signs of wear, leakage, or damage. Check the press connection for any visible deformation or misalignment. If the fitting is suspected of being improperly pressed, it must be removed and reinstalled using the correct procedure. No specific service intervals are provided, but any issues should be addressed immediately to prevent system failure.

Frequently asked questions

Can the IVAR IVN64.4216 be connected to a copper pipe?
No, this fitting is specifically designed for stainless steel press pipes and is not compatible with copper pipes.

Is the O-ring replaceable after installation?
No, the O-ring is part of the fitting and cannot be replaced once the fitting has been pressed onto the pipe.

Can the fitting be used in high-vibration environments?
Yes, the stainless steel construction and secure press connection make it suitable for environments with moderate vibration levels.

What should be done if the fitting does not press correctly?
If the fitting does not compress properly, it should be removed and the pipe end inspected for damage or debris. The fitting must be replaced if it has been damaged during the attempt.
