O-ring - for PRESS fittings brass - 63x4,5 IVAR.OR

Product detailed description

This EPDM O-ring is used in the installation of water supply, heating and fire protection systems where reliable sealing is essential. It is commonly used in residential and commercial buildings, including industrial facilities, where IVAR PRESS fittings are employed for connecting copper or plastic pipes. The O-ring ensures a tight, leak-free connection in systems operating within the specified temperature range. It is particularly suited for applications where the system is exposed to both cold and hot conditions, such as in underfloor heating or domestic hot water circuits.

The O-ring is installed within the fitting groove to create a compressive seal when the fitting is pressed onto the pipe. It is designed to maintain its integrity under normal operating conditions and is selected based on the fitting size and system requirements. The material and dimensions are chosen to ensure compatibility with the fitting geometry and to withstand the expected mechanical and thermal stresses during installation and operation.

Technical parameters

Installation and connection

During installation, the O-ring is placed into the designated groove within the fitting. The fitting is then pressed onto the prepared pipe using a suitable pressing tool. The O-ring must be free of damage and properly seated in the groove to ensure a secure connection. The fitting must be aligned correctly with the pipe to prevent misalignment, which could lead to leaks or damage to the O-ring. Common installation errors include using a damaged or incorrectly sized O-ring, or failing to clean the fitting groove before installation. It is important to inspect the O-ring for any signs of wear or deformation before use.

Compatibility and accessories

This O-ring is specifically designed for use with IVAR PRESS brass fittings. It is compatible with standard fitting sizes and is used in conjunction with the appropriate pressing tools and pipe materials. When ordering, it is important to ensure that the correct size and type of O-ring is selected to match the fitting and system requirements. No additional accessories are required for standard installation, but it is recommended to have replacement O-rings on hand for maintenance or rework.

Technical background for designers

The O-ring functions as a compressive seal between the fitting and the pipe. When the fitting is pressed onto the pipe, the O-ring is compressed within the groove, creating a tight, leak-free connection. The EPDM material is chosen for its flexibility and resistance to water and common system fluids. The sealing surface of the O-ring must be compatible with the fitting geometry and the expected mechanical and thermal stresses. The service life of the O-ring is influenced by factors such as installation quality, system pressure, and operating temperature. Proper selection and installation are essential to ensure long-term performance and system integrity.

Service and operation

During operation, the O-ring requires no active maintenance. However, it is important to periodically inspect the connection for signs of leakage or wear. If a leak is detected, the fitting should be removed and the O-ring inspected for damage or deformation. In such cases, the O-ring should be replaced with a new one of the same type and size. There are no defined service intervals for this component, as it is designed for long-term use under normal operating conditions. Any replacement should be carried out by a qualified technician to ensure the correct installation and system performance.

Frequently asked questions

Can this O-ring be used with other types of IVAR fittings?
This O-ring is specifically designed for use with IVAR PRESS brass fittings. It is not compatible with other fitting types or brands.

Is this O-ring suitable for potable water systems?
Yes, the EPDM material is suitable for use in potable water systems and meets the necessary requirements for water contact applications.

What temperature range is this O-ring rated for?
The O-ring is rated for operation between -20°C and +120°C, making it suitable for both cold and hot water systems.

Can the O-ring be reused after removal?
No, the O-ring is designed for single use only. Once removed or deformed, it should be replaced with a new one to ensure a reliable seal.
