Press jaw F - F26/26mm IVAR.CEL F

Product detailed description

The press jaw F26/26mm is part of a precision toolset used in the installation of press-fit pipe systems. This type of fitting is commonly used in residential, commercial and industrial buildings for heating, plumbing and irrigation systems. Installers and contractors rely on press jaws to ensure secure, leak-free connections in copper or plastic piping. The system requires accurate alignment and pressure application to create a reliable joint. Proper selection of press jaws ensures compatibility with the fitting type and pipe diameter.

Installation typically involves preparing the pipe ends, fitting the crimp ring, positioning the press jaw correctly, and applying the required force through a compatible press. The process is repeated for each connection, and multiple joints may be needed in a single installation. The press jaw must be compatible with the system’s fitting design and the press unit to ensure correct deformation of the crimp ring. In complex systems, such as underfloor heating or large-scale plumbing, the correct press jaws are essential for maintaining system integrity.

Technical parameters

Installation and connection

Installation begins by cutting the pipe cleanly and deburring the end. The crimp ring is then slid onto the pipe, followed by the fitting. The press jaw is placed over the joint, ensuring it aligns with the fitting’s groove. The press is activated to apply even pressure until the crimp ring is fully deformed. After pressing, the joint should be visually inspected for symmetry and correct deformation. Common mistakes include misalignment of the jaw, using incorrect jaw sizes, or failing to clean the pipe ends properly. These can lead to leaks or weak joints.

Compatibility and accessories

This press jaw is compatible with IVAR.ALPEX press fittings and works with the IVAR.POWER-PRESS and IVAR.POWER-PRESS ACC electric hydraulic presses. For certain applications, an intermediate jaw (IVAR.MC Z4) may be required for larger fittings. To complete the installation, the IVAR.TH 17 press jaws can be used for IVAR.AC fittings in parallel systems. When ordering, ensure all required press jaws and accessories are included for the specific system being installed.

Technical background for designers

The press jaw operates by applying controlled radial force to the crimp ring, which deforms it around the pipe and fitting. The material of the press jaw is typically hardened steel to resist wear and maintain dimensional accuracy over time. The design allows for even pressure distribution to prevent damage to the pipe or fitting. The system integrates with standard press-fit tools and requires no additional sealing agents. Long-term performance depends on correct installation, proper jaw selection and the quality of the press unit. Frequent use without maintenance can lead to wear and reduced effectiveness.

Service and operation

Periodic inspection of the press jaw is recommended to detect signs of wear, such as deformation or scoring. The jaw should be cleaned after each use to remove debris or residue that could affect performance. If the jaw shows uneven deformation patterns or fails to seat correctly in the press unit, it should be replaced. No specific service intervals are provided, but routine checks during installation are advised to ensure consistent joint quality.

Frequently asked questions

Can the press jaw F26/26mm be used with IVAR.AC fittings?
No, this jaw is designed specifically for IVAR.ALPEX fittings. For IVAR.AC fittings, the IVAR.TH 17 press jaw is required.

Is an intermediate jaw required when using the F26/26mm press jaw?
Not for standard applications. However, for larger fittings, the IVAR.MC Z4 intermediate jaw may be needed depending on the system design.

Can this press jaw be used with any IVAR press unit?
It is compatible with IVAR.POWER-PRESS and IVAR.POWER-PRESS ACC units. Other models may require verification against the manufacturer’s technical data.

What should be checked after pressing to ensure a good joint?
Visually inspect the crimp ring for even deformation and symmetry. Ensure the press jaw is fully seated and the joint shows no gaps or irregularities.
