Extension 108 x 108

Product detailed description

Press extensions are essential components in closed pressurised systems where welding or threading is not feasible. The IVAR IVC11.108 model is commonly used in central heating, fire protection, and industrial air systems. It provides a reliable connection in environments with fluctuating temperatures and high-pressure demands. Installers working in commercial and industrial buildings often use this extension for ductwork in HVAC, refrigeration, and solar systems. The absence of surface coatings and the use of EPDM seals make it suitable for dry air, inert gases, and non-potable water applications.

Correct selection of press extensions is crucial for system integrity. The IVC11.108 is sized for 108 mm diameter pipes and is designed to handle the mechanical and thermal stresses of its intended applications. It is particularly useful in systems where rapid installation is required and where the working environment includes both cold and hot conditions.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	1.86 kg
Code	IVC11.108
Brand	IVAR

The operating temperature range of -20°C to +120°C allows for use in both cold and hot systems. The nominal pressure rating of PN 16 means it can handle pressures up to 16 bar, making it suitable for high-pressure applications. These parameters are essential for determining compatibility with other system components and ensuring long-term performance.

Installation and connection

The IVC11.108 press extension is installed using Type M jaws, which are specifically designed for this fitting type. The connection is made by inserting the pipe into the fitting and crimping it with the jaws until the crimp indicator is reached. The 108 mm diameter requires precise alignment and a secure crimp to prevent leaks. Installers should verify that the pipe is free of burrs and that the O-ring is undamaged before crimping. Common mistakes include over-crimping, which can damage the O-ring, and under-crimping, which can lead to leaks. It is important to follow the manufacturer's crimping guidelines for this size and material.

Compatibility and accessories

The IVC11.108 is compatible with other IVAR press fittings and components within the same system. It is designed to work with carbon galvanized steel pipes of the same diameter. For installation, Type M jaws are required. No additional surface treatments or coatings are needed, and no special tools are required beyond standard press equipment. No related products are listed for this model.

Technical background for designers

The IVC11.108 press extension operates on the principle of mechanical crimping, which creates a leak-proof joint without the need for welding or threading. The carbon galvanized steel material provides good corrosion resistance and mechanical strength. The EPDM O-ring ensures a tight seal under varying pressure and temperature conditions. When integrated into a system, the extension must be sized correctly to match the pipe diameter and system pressure. The material's properties affect the system's durability and efficiency, particularly in environments with high thermal cycling or mechanical stress.

Service and operation

The IVC11.108 requires no regular maintenance under normal operating conditions. However, periodic visual inspections are recommended to check for signs of mechanical damage or corrosion. The crimped joint should remain intact and leak-free unless subjected to external forces or incorrect installation. No specific service intervals are provided for this model.
