Press jaw F - F40/40mm IVAR.CEL F

Product detailed description

Press jaws like the IVAR model F40/40mm are essential components in the installation of press-fit plumbing and heating systems. They are commonly used in residential and commercial buildings where reliable, leak-free joints are required. These jaws ensure accurate alignment and even pressure distribution during the pressing process, which is critical in systems such as underfloor heating, domestic hot and cold water supply, and central heating circuits. Installers working with these jaws typically handle copper, stainless steel, and cross-linked polyethylene (PE-X) piping, all of which require precise pressing techniques to maintain system integrity.

The pressing process involves securing the pipe and fitting within the jaw cavity and applying hydraulic force via a compatible pressing tool. This creates a permanent joint that eliminates the need for soldering or threading. The F40/40mm model is specifically engineered for 40 mm nominal pipe diameters, making it suitable for larger-diameter applications such as main supply lines or high-flow systems. The design of the jaw ensures compatibility with the IVAR.ALPEX system, which is known for its ease of installation and long-term reliability in press-fit connections.

Technical parameters

Installation and connection

When installing using the IVAR Press Jaw F40/40mm, the first step is to prepare the pipe and fitting by ensuring they are clean, straight, and free from burrs. The fitting is then slid onto the pipe until it reaches the stop mark. The press jaw is placed over the assembly, and the electrohydraulic pressing tool is engaged. It is important to align the jaw correctly with the fitting to avoid misalignment, which can lead to weak or failed joints. After pressing, the installer should inspect the joint visually and, if necessary, perform a pressure test to confirm its integrity. Common mistakes include using incorrect jaw sizes, failing to clean the pipe ends, or applying uneven pressure during pressing.

Compatibility and accessories

This press jaw is specifically compatible with the IVAR.POWER-PRESS and IVAR.POWER-PRESS ACC electrohydraulic pressing units. For a complete installation setup, it is recommended to use it with the IVAR.ALPEX system fittings and pipes. Additional accessories such as pressing tools, cleaning brushes, and calibration devices may also be required depending on the project scale and complexity. Installers should ensure that all components are from the same manufacturer and system to guarantee full compatibility and optimal performance.

Technical background for designers

The operating principle of the IVAR Press Jaw F40/40mm is based on mechanical deformation of the fitting and pipe wall through controlled hydraulic pressure. The jaw is manufactured from durable materials that resist wear and deformation during repeated use. Its design allows for consistent pressing depth and alignment, which is essential for maintaining system pressure ratings and long-term performance. Integration into the overall system requires careful planning to match the jaw size with the pipe and fitting dimensions. Factors such as pipe material, wall thickness, and system pressure will influence the choice of jaw and pressing method. Properly pressed joints contribute to the overall efficiency and longevity of the installation.

Service and operation

Regular inspection of the press jaw is recommended to ensure it remains free from damage or wear that could affect pressing accuracy. Any visible deformation or cracks should be addressed immediately by replacing the jaw. During operation, it is important to follow the manufacturer’s guidelines for pressing force and cycle times to avoid overloading the tool or the jaw itself. No specific service intervals are provided, but routine checks are advised to maintain optimal performance.

Frequently asked questions

Can the IVAR Press Jaw F40/40mm be used with other pressing units besides IVAR.POWER-PRESS?
It is specifically designed for use with the IVAR.POWER-PRESS and IVAR.POWER-PRESS ACC models. Using it with other brands or models is not recommended as it may compromise the quality of the joint.

Is it possible to reuse the IVAR.ALPEX fittings after pressing?
No, once a fitting has been pressed using the IVAR system, it cannot be reused. The deformation caused during pressing is irreversible and the joint is considered permanent.

What type of piping is suitable for use with this press jaw?
The jaw is intended for use with IVAR.ALPEX system fittings and compatible piping. The specific materials and dimensions should be verified according to the manufacturer’s technical data sheet.

How can I ensure the correct alignment of the press jaw during installation?
Proper alignment can be achieved by placing the jaw centrally over the fitting and pipe assembly before engaging the pressing tool. Visual checks and, where applicable, calibration tools can help confirm correct positioning.
