Extension - 12x3/8" IVAR.1530 G

Product detailed description

Brass threaded extensions are essential components in the installation and maintenance of heating, plumbing and sanitation systems. They allow for precise alignment and connection of pipes in confined spaces, such as under sinks, behind panels or within walls. In residential and commercial buildings, these fittings are commonly used in central heating systems, hot and cold water distribution, and in irrigation circuits. Technicians often need to adapt pipe lengths or connect components with mismatched thread positions. This extension ensures a secure and leak-free connection in such scenarios.

When working with copper or plastic piping, it is crucial to ensure that the fitting is compatible with the system’s operating conditions. The CW617N brass used in this extension is known for its corrosion resistance and suitability for water-based systems. It allows for reliable performance in both low-temperature hot water systems and higher-pressure environments. Installers should also consider the thermal expansion of the system and ensure that the fitting is not over-tightened, which can lead to stress fractures over time.

Technical parameters

Material	Brass CW617N ATEST for potable water
Operating temperature	+120 °C
Nominal pressure	PN 10
Code	1530G0310
Brand	IVAR

The operating temperature limit of +120°C is suitable for most domestic and light commercial hot water systems. The PN10 pressure rating indicates that the fitting can handle nominal pressures up to 10 bar, making it appropriate for standard water supply lines and heating circuits. These parameters help determine whether the fitting is suitable for the intended application and ensure that it will perform reliably under expected conditions.

Installation and connection

To install this extension, align the male and female threads and hand-tighten initially to avoid cross-threading. Use a wrench to tighten further, ensuring that the joint is secure without over-torquing. The 3/8 inch thread size is commonly used in small-diameter piping systems. Before final tightening, check that the threads are clean and free from debris. Common mistakes include using incorrect thread sealant or failing to apply a proper seal, which can result in leaks. Always verify the alignment of the connected components to prevent stress on the fitting during operation.

Compatibility and accessories

This extension is designed to work with standard 3/8 inch threaded fittings and components. It is suitable for use with copper, PEX and polypropylene pipes when the correct sealing method is applied. Additional items such as thread sealant or Teflon tape may be required depending on the system. No specific related products are recommended for this model.

Technical background for designers

This extension functions as a passive component in the system, allowing for length adjustment between threaded components. The CW617N brass is chosen for its durability and compatibility with potable water systems. Its resistance to dezincification and pitting ensures long-term reliability. The PN10 rating is based on the material’s ability to withstand internal pressure at the specified operating temperature. For optimal performance, the fitting should be installed in a way that minimises thermal stress and mechanical vibration.

Service and operation

No regular maintenance is required for this extension. However, during routine inspections, it is advisable to check for signs of leakage, corrosion or mechanical damage. If the fitting is part of a system that experiences frequent thermal cycling, ensure that it remains properly sealed and undamaged. There are no defined service intervals for this component.

Frequently asked questions

Can this extension be used in a potable water system?
Yes, the CW617N brass is certified for use with drinking water, ensuring compliance with relevant standards.

Is this fitting suitable for hot water applications?
Yes, the maximum operating temperature of +120°C makes it suitable for hot water systems and heating circuits.

What sealing methods are recommended for this fitting?
Thread sealant or Teflon tape is recommended to ensure a watertight connection. Always follow the manufacturer’s guidelines for the specific system.

Can this extension be used in a closed-loop heating system?
Yes, provided that the system’s operating pressure does not exceed the PN10 rating and the temperature remains within the specified range.
