Press head - 20mm; 1" IVAR.SITE-LH

Product detailed description

The press head is a critical tool in the installation of flexible stainless steel piping systems, commonly used in residential and commercial buildings for heating, water supply and sanitation applications. It ensures accurate and secure compression of fittings onto corrugated stainless steel tubes, which are known for their corrosion resistance and flexibility. Installers typically use this tool in tight spaces or where traditional rigid pipework would be impractical, such as under sinks, behind walls, or in boiler rooms. The correct press head is essential for ensuring leak-tight joints and long-term system integrity.

When working with stainless steel corrugated tubing, precision is vital to avoid over-compression or misalignment, which can lead to joint failure. This press head is specifically sized for 20 mm (1 inch) diameter systems and should be used in conjunction with the appropriate press tool and cutting guide to ensure clean, accurate cuts and consistent compression. The design accommodates the standard wall thickness and corrugation pattern of the tubing, ensuring reliable performance in both low-pressure and high-pressure applications.

Technical parameters

Code	M1600002
Brand	IVAR

This press head is designed for 20 mm (1 inch) diameter stainless steel corrugated tubing. It is used in accordance with the manufacturer’s specifications for tooling and fitting dimensions. Sizing is based on external diameter and nominal bore to ensure compatibility with IVAR fittings and other compatible components.

Installation and connection

To install, begin by cutting the tube cleanly using a suitable cutting tool. Remove any burrs or debris from the cut end using a deburring tool. Slide the fitting onto the tube until it reaches the stop mark. Position the press head correctly on the fitting and apply even pressure using the recommended press tool. Ensure the press head aligns with the fitting’s outer surface and does not shift during compression. Common mistakes include misalignment of the press head, over-pressing, or using incorrect tooling. Always verify the fit after pressing by gently rotating the fitting to confirm a secure connection.

Compatibility and accessories

This press head is compatible with IVAR stainless steel corrugated tubing and fittings designed for 20 mm (1 inch) diameter systems. For complete installation, ensure that you have the correct press tool, cutting guide, and deburring tool. Accessories such as sealing rings and mounting brackets may also be required depending on the application and local regulations. Refer to the manufacturer’s guidelines for full compatibility and recommended combinations.

Technical background for designers

The press head operates by applying uniform force around the circumference of the fitting to compress it onto the tube, creating a mechanical and watertight seal. The stainless steel material offers excellent durability and resistance to corrosion, making it ideal for both hot and cold water applications. The corrugated design allows for flexibility and vibration damping, reducing stress on joints. System efficiency depends on correct alignment, proper press depth, and the use of compatible fittings. Longevity is maximised when installed in accordance with the manufacturer’s instructions and local standards.

Service and operation

Routine checks should be performed periodically to ensure all joints remain intact and free from leaks. Look for signs of wear, misalignment, or damage to the press head itself. If the press head shows visible deformation or wear, replace it immediately to maintain installation accuracy. No scheduled maintenance is required beyond visual inspection and replacement when necessary.

Frequently asked questions

Can this press head be used with other brands of stainless steel tubing?
It is designed for IVAR stainless steel corrugated tubing and fittings. Use with non-compatible tubing may result in improper compression and joint failure.

What happens if the press head shifts during compression?
If the press head moves off-centre, the resulting joint may be uneven or incomplete. Stop the process, reposition the head, and re-press the fitting to ensure a uniform seal.

Is it possible to re-use a fitting after pressing?
No. Once a fitting has been compressed, it cannot be removed or re-used. Any damaged or improperly pressed joints must be cut out and replaced with new fittings and tubing.

How do I know if the press was successful?
A properly pressed joint will show even compression marks around the entire circumference of the fitting. Visually inspect the joint and test the system for leaks after installation to confirm integrity.
