Connection fitting - externally threaded, 22 x R1

Product detailed description

This external-threaded connection fitting is part of the IVAR IVC64 series and is commonly used in closed-loop heating systems, industrial air and gas lines, and fire suppression circuits. Installers working with central heating, cooling circuits, and pressurised water supply lines will find this fitting suitable for connecting press-fit pipe systems to threaded components. It supports both high-pressure and high-temperature environments, making it ideal for applications such as boiler feedlines, industrial process lines, and climate control installations.

The fitting is typically installed in dry or semi-dry environments where mechanical durability and thermal resistance are required. It is compatible with a range of pipe systems and is frequently used in conjunction with standard flaring tools and compression techniques. The fitting is not approved for potable water use due to material composition and coating limitations.

Technical parameters

Material	carbon steel galvanized
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressure up to	16 bar
Weight	0.232 kg
Code	IVC64.2210
Brand	IVAR

The operating temperature range of -20°C to +120°C allows for use in cold and hot environments. The nominal pressure rating of PN16 and maximum pressure resistance of 16 bar ensure safe operation under high-pressure conditions. These parameters are essential when selecting the correct fitting for a given hydraulic load and environmental exposure.

Installation and connection

To install the fitting, align the press-fit end with the corresponding pipe and apply the appropriate flaring tool. Ensure the thread side is clean and free from debris before screwing it into the mating component. The connection size is 22 mm (press-fit) and R1 (external thread), requiring matching internal threads on the receiving end. Key checkpoints during installation include verifying the alignment between the press-fit end and pipe, ensuring a secure and leak-free connection by tightening to the recommended torque for the thread type, and confirming the absence of surface coatings that could interfere with sealing. Common mistakes include over-tightening, which can damage the EPDM O-ring, and using incompatible thread types, which may lead to leakage or failure.

Compatibility and accessories

This fitting is compatible with IVAR press-fit systems and standard R1 internal threads. It should be used with pipes and fittings of the same series and with compatible compression tools. Accessories such as flaring tools and lubricants may be needed for efficient installation. Related products include other IVAR IVC62 and IVC64 series fittings, as well as standard press-fit pipe systems.

Technical background for designers

The fitting operates via a mechanical press-fit and threaded connection, relying on the EPDM O-ring for sealing. The carbon steel body provides good mechanical strength and corrosion resistance in non-aggressive environments. The material’s properties allow it to maintain structural integrity over time, provided it is not exposed to aggressive media or prolonged high temperatures beyond its limits. Integration into a system requires careful consideration of flow rates, pressure drops, and thermal expansion characteristics of the connected piping.

Service and operation

No specific service intervals are defined for this fitting. During routine maintenance, inspect the connection for signs of wear, leakage, or corrosion, particularly around the EPDM O-ring and thread interface. If any degradation is observed, replace the fitting immediately to prevent system downtime. Ensure the installation site remains dry and free from chemical exposure to extend service life.
