Connection set for stainless steel bellows pipes IVAR.SITE-TR - 12mm; 1/2" IVAR.SITE-PS

Product detailed description

This connection set is intended for use with IVAR.SITE-TR flexible stainless steel bellows pipes, commonly applied in residential and commercial heating and plumbing systems. Installers and technicians working on systems where flexibility is required—such as in tight spaces, around obstacles or where vibration isolation is necessary—will benefit from the ease of installation and reliable sealing provided by this set. The components are suitable for both new installations and repairs, ensuring secure and leak-free connections in water-based systems.

The set provides all necessary mechanical components for assembling multiple flexible pipe joints. It is particularly useful in applications where the pipe route requires frequent directional changes or where expansion compensation is needed. The stainless steel construction ensures resistance to corrosion, making it suitable for long-term use in environments with fluctuating temperatures and pressures.

Technical parameters

Installation and connection

To assemble the connection, the ferrule is placed over the end of the bellows pipe, followed by the nut. The sealing washer is positioned between the ferrule and the mating surface. The nut is then tightened to compress the ferrule against the pipe and the sealing washer, creating a secure and watertight seal. The connection size is 12 mm / 1/2 inch, and the threads are standard for this type of flexible piping. It is important to ensure that the ferrule is seated correctly and that the nut is tightened evenly to avoid uneven compression or leakage.

Common installation errors include over-tightening the nut, which can damage the ferrule or the pipe, and improper alignment of the ferrule on the pipe. It is also essential to verify that the mating surface is clean and free of debris before tightening. The set does not include a crimping head, so a compatible tool must be used separately for installation.

Compatibility and accessories

This set is specifically designed for IVAR.SITE-TR flexible stainless steel bellows pipes. It is not compatible with other types of flexible piping or rigid pipe systems. To complete the installation, a crimping tool suitable for these pipes must be used. The set does not include such a tool, so it must be ordered separately. The components are also compatible with standard pipe fittings and valves that accept 1/2 inch connections. For larger installations, additional sets may be required depending on the number of joints needed.

Technical background for designers

The flexible stainless steel bellows pipe allows for angular movement and expansion compensation while maintaining a secure seal. The stainless steel material offers high resistance to corrosion and mechanical stress, making it suitable for both hot and cold water applications. The ferrule and nut assembly compresses the pipe tightly against the fitting, preventing leakage and ensuring a long service life. The design of the connection allows for disassembly and reassembly without compromising the integrity of the joint, provided the components are not damaged during removal.

When designing a system using these pipes, it is important to account for the flexibility of the bellows and ensure that the routing allows for proper movement without kinking or excessive bending. The sealing performance is influenced by the correct installation technique, the quality of the mating surfaces and the even tightening of the nuts. The system should be tested for leaks after installation and periodically checked for signs of wear or loosening.

Service and operation

During operation, the connection requires minimal maintenance. However, it is recommended to visually inspect the joints periodically for signs of leakage, corrosion or loosening. If any issues are detected, the affected joint should be disassembled and the components inspected for damage. The sealing washer should be replaced if it shows signs of wear or deformation. The ferrules and nuts can typically be reused unless they are visibly damaged. There are no specified service intervals for this component, but regular checks are advised in high-traffic or high-pressure systems.

Frequently asked questions

Can this set be used with other types of flexible piping?
No, this set is specifically designed for IVAR.SITE-TR stainless steel bellows pipes. Using it with other types of piping may result in poor sealing or damage to the components.

How many joints can be assembled with this set?
Up to 20 individual joints can be assembled using the 20 nuts, 20 ferrules and 20 sealing washers included in the set.

Is a crimping tool required for installation?
Yes, the set does not include a crimping head. A suitable crimping tool must be used separately to compress the ferrule and create a secure joint.

Can the components be reused after disassembly?
The ferrules and nuts can typically be reused unless they are damaged. The sealing washers should be replaced after each disassembly to maintain a watertight seal.
