Connection fitting FASTEC - 26x3; FASTEC Quick IVAR.F 13

Product detailed description

Quick connection fittings are essential components in modern heating and plumbing systems, especially in residential and commercial buildings using flexible plastic piping. These fittings allow for rapid and secure connections without the need for soldering or threading. Installers working with PEX or ALPEX pipes often rely on such fittings to streamline installation processes and reduce downtime. In systems requiring frequent adjustments or maintenance, the ability to disconnect and reconnect components quickly is a significant advantage.

In multi-family housing, industrial facilities and large-scale commercial developments, the use of compression fittings ensures consistent performance and reliability. These fittings are commonly found in domestic hot and cold water systems, underfloor heating circuits and other applications where flexibility and durability are required. The design minimises the risk of leaks while allowing for easy inspection and replacement when necessary.

Technical parameters

Material	Brass
Operating temperature	+90 °C
Nominal pressure	PN 10
Code	511122MP
Brand	IVAR

The operating temperature limit of +90 °C makes this fitting suitable for hot water systems and underfloor heating applications. The PN 10 rating indicates its ability to handle medium-pressure conditions, which is typical for most domestic and light commercial systems. These parameters are crucial for selecting the correct fitting size and type during system planning and design stages.

Installation and connection

To install the fitting, the installer must first prepare the end of the PEX or ALPEX pipe by ensuring it is cut straight and free from burrs. The pipe is then inserted into the fitting until it reaches the stop mark, and the compression ring is positioned correctly. The fitting is secured using a suitable crimping tool, ensuring a tight and leak-free connection. It is important to verify that the pipe is fully seated and that the tool is aligned properly to avoid misalignment or damage to the fitting. Common mistakes include over-crimping, which can deform the fitting and compromise its integrity, and under-crimping, which may result in a loose connection. Always check the alignment and depth of insertion before applying the crimping force. After installation, the connection should be tested under pressure to confirm its functionality.

Compatibility and accessories

This connection fitting is specifically designed for use with PEX and ALPEX pipes. To complete the installation, appropriate crimping tools and pipe cutters must be available. While no alternative or related products are specified, it is recommended to have spare fittings and tools on site to ensure continuity during installation.

Technical background for designers

The operating principle of this fitting relies on mechanical compression to create a seal between the pipe and the fitting body. The brass material offers good corrosion resistance and thermal conductivity, making it well-suited for use in both hot and cold water systems. When integrated into a larger system, the fitting’s PN 10 rating ensures compatibility with standard pressure conditions found in most residential and light commercial applications. The longevity of the fitting depends on proper installation, regular inspection, and the absence of excessive vibration or thermal cycling.

Service and operation

Routine maintenance involves visual inspections for signs of wear, corrosion or leakage. If a connection shows signs of failure, it should be replaced immediately. There are no specified service intervals in the product data, but periodic checks are recommended as part of general system maintenance. Always ensure that the system is depressurised before attempting to inspect or replace any components.

Frequently asked questions

Can this fitting be used with copper pipe?
No, this fitting is designed for PEX and ALPEX pipe only. Using it with copper would require a different type of connection method and fitting.

Is this fitting suitable for hot water systems?
Yes, the maximum operating temperature of +90 °C makes it appropriate for hot water applications, including underfloor heating and domestic hot water distribution.

Can multiple fittings be installed in series without affecting system pressure?
Yes, provided that all fittings are installed correctly and the overall system pressure remains within the PN 10 specification. Each connection should be individually tested for leaks.

What tool is required for installation?
A compatible crimping tool is needed to compress the fitting onto the pipe. The tool must be calibrated and in good condition to ensure a reliable connection.
