Press jaw PB2-M - M28;28mm IVAR.PB2-M

Product detailed description

The IVAR.PB2-M press jaw is a critical component in press-fitting systems used in modern plumbing and heating installations. These jaws are commonly employed in residential, commercial, and industrial buildings where copper or stainless steel pipe systems require secure and leak-free connections. Installers working with IVAR.C-STEEL or IVAR.INOX fittings rely on this tool to ensure accurate pressing operations during system assembly. The press jaw ensures consistent force distribution across the fitting, creating a durable mechanical bond between the pipe and fitting.

Proper use of the IVAR.PB2-M press jaw is essential in systems that demand high integrity and long-term performance. It is typically used in conjunction with electro-hydraulic presses that offer precise control over pressing force and stroke. This makes it suitable for installations where even minor deviations can lead to system failure, such as in closed-loop heating circuits or potable water supply lines. The press jaw supports the transition from traditional soldering techniques to more modern, faster and safer press-fit methods.

Technical parameters

Installation and connection

To install the IVAR.PB2-M press jaw, align the jaw with the fitting and ensure that the fitting is correctly seated within the pipe. Use the electro-hydraulic press tool to apply even pressure until the fitting is fully pressed onto the pipe. Check that the press mark extends evenly around the circumference of the fitting. Common installation errors include misalignment of the fitting or insufficient pressure, both of which can result in weak joints or leaks. Always verify the fit before proceeding to the next connection.

Compatibility and accessories

This press jaw is specifically designed for use with IVAR.C-STEEL and IVAR.INOX press fittings. It requires the IVAR.ACO 203 XL BT electro-hydraulic press tool for operation. To complete a full installation setup, additional accessories such as replacement dies, calibration tools and protective covers should be considered. These items help maintain the longevity and accuracy of the press tool over time.

Technical background for designers

The IVAR.PB2-M press jaw operates by applying controlled hydraulic pressure through a calibrated die to deform the fitting around the pipe. This creates a permanent mechanical bond without the need for heat or adhesives. The jaws are manufactured from hardened steel to resist wear and deformation under repeated use. Proper integration into the system depends on correct alignment with the pipe and fitting dimensions, ensuring a tight and reliable joint. The choice of material and pressing technique directly affects the joint’s resistance to vibration, thermal expansion and internal pressure.

Service and operation

Regular inspection of the press jaw is necessary to detect signs of wear or damage that could affect pressing quality. Clean the jaw surfaces after each use to remove debris or residue that might interfere with the fit. Ensure that the jaw is properly aligned with the press tool and that all fastening components are intact. If the jaw shows signs of misalignment or uneven wear, it should be replaced immediately to avoid compromising the integrity of the joints.

Frequently asked questions

Can the IVAR.PB2-M press jaw be used with non-IVAR fittings?
No, the IVAR.PB2-M is specifically designed for IVAR.C-STEEL and IVAR.INOX press fittings. Using it with other brands may result in improper pressing and unreliable joints.

Is it possible to reuse the IVAR.PB2-M press jaw after multiple pressing operations?
Yes, provided the jaw remains undamaged. However, regular inspections are recommended to confirm that the pressing surface is still smooth and even. Worn jaws should be replaced to maintain joint quality.

What is the maximum number of pressing cycles the jaw can handle?
According to the manufacturer’s technical data sheet, the number of pressing cycles will vary depending on usage conditions. Replace the jaw when signs of wear or deformation appear.

How do I know if the jaw is correctly aligned with the fitting?
Correct alignment is indicated by an even press mark around the full circumference of the fitting. If the mark appears uneven or incomplete, the jaw may be misaligned or damaged.
