Sealing washer - water - 12mm; 1/2" IVAR.FASIT 202 W

Product detailed description

Sealing washers are essential components in water systems where flexible stainless steel piping is used. They are typically installed in domestic and commercial plumbing systems to ensure a watertight connection between the pipe and the fitting. In installations involving IVAR flexible stainless steel pipes, these washers are used in conjunction with compression fittings, ball valves, or other types of connectors. The 12mm / 1/2 inch size is commonly used for domestic water supply lines, including connections to taps, mixers, and under-sink filters. The washer is designed to compress slightly during installation, forming a reliable seal that prevents leaks and maintains system integrity.

Proper installation of sealing washers is crucial to the long-term performance of the system. Installers must ensure that the washer is not damaged during handling and that it is correctly positioned within the fitting. The washer must also be compatible with the type of pipe and fitting being used. In systems where frequent disassembly is required, such as for maintenance or replacement of components, the washer must be inspected for wear and replaced if necessary to maintain a secure connection.

Technical parameters

Installation and connection

Installation of the sealing washer involves placing it inside the fitting before inserting the pipe. The pipe is then pushed through the fitting until it reaches the stop, ensuring that the washer is compressed between the pipe and the fitting. The connection is tightened using a suitable tool, such as a compression ring wrench, to secure the fitting in place. It is important to avoid over-tightening, which can damage the washer or the fitting. Before final tightening, the installer should check that the washer is not twisted and that the pipe is fully seated in the fitting. Common installation errors include using the wrong size washer, reusing a damaged washer, or failing to clean the pipe and fitting surfaces before assembly.

Compatibility and accessories

This sealing washer is specifically designed for use with IVAR flexible stainless steel pipes and compatible fittings. It is typically used in conjunction with compression fittings, ball valves, or other types of connectors that require a sealing element. When assembling a system, installers should ensure that all components are from the same manufacturer or are certified for use with IVAR products. Additional accessories that may be required include compression rings, pipe cutters, and deburring tools. For larger systems or where multiple connections are needed, it is advisable to have a supply of spare washers on hand for replacements during installation or maintenance.

Technical background for designers

The sealing washer functions by compressing between the pipe and the fitting to create a watertight seal. It is typically made from a resilient material that can withstand repeated compression without losing its shape or sealing properties. The washer is designed to work with the flexibility of the stainless steel pipe, allowing for slight movement without compromising the seal. In the system, the washer plays a critical role in maintaining pressure integrity and preventing leaks. The service life of the washer is influenced by factors such as the quality of the installation, the frequency of disassembly, and the operating conditions of the system. Proper selection and installation are essential to ensure long-term performance.

Service and operation

During operation, the sealing washer requires minimal maintenance. However, it should be inspected during routine system checks for signs of wear, such as cracking or flattening. If the washer is found to be damaged or has been used in a disassembled connection, it should be replaced immediately to prevent leaks. There are no specific service intervals for this component, but it is recommended to replace the washer whenever the connection is disassembled for maintenance or repair. In high-use systems, such as those in commercial buildings, more frequent inspections may be necessary to ensure continued performance.

Frequently asked questions

Can this sealing washer be used with other brands of flexible stainless steel pipe?
It is recommended to use this washer only with IVAR flexible stainless steel pipes and fittings. Compatibility with other brands is not guaranteed and may affect the sealing performance.

Is it possible to reuse the sealing washer after disassembly?
It is not advisable to reuse the washer once it has been compressed. Reuse may lead to reduced sealing effectiveness and potential leaks.

What should be done if the washer is damaged during installation?
If the washer is damaged, it should be replaced with a new one before proceeding with the installation to ensure a secure and leak-free connection.

Can this washer be used in high-pressure water systems?
Yes, provided that the system pressure is within the limits specified by the manufacturer for IVAR flexible stainless steel pipes and fittings.
