O-ring GAS - 18mm (yellow) IVAR.IVO.HNBR Z

Product detailed description

In professional heating and industrial installations, O-rings play a vital role in ensuring leak-tight connections between press-fit components. This 18mm yellow O-ring is specifically designed for use in press-fitting systems where gas or compressed air is transported. Installers working on medical technology systems, sprinkler systems, heating systems, and industrial gas lines will find this sealing ring essential for maintaining system integrity under variable operating conditions.

Typical applications include solar thermal systems, compressed air networks, and low-pressure gas distribution. The O-ring is inserted into a press-fit socket and compressed during installation to form a secure seal. It is important to ensure that the mating components are compatible with press-fit technology and that the installation tool is correctly calibrated to avoid over-compression or under-compression, which can lead to premature failure.

Technical parameters

Installation and connection

During installation, the O-ring is placed into the socket of a press-fit fitting before the pipe is inserted. The press-fit tool compresses the fitting around the pipe and the O-ring, forming a tight seal. The system must be checked for proper compression using the manufacturer’s indicator marks to ensure the fitting is fully engaged. Common installation errors include incorrect alignment of the pipe, insufficient or excessive compression, and the use of incompatible tools. Always verify that the press-fit system is compatible with the O-ring before installation.

Compatibility and accessories

This O-ring is intended for use with press-fit systems that support the specified dimensions. It is not a standalone component but part of a larger sealing system involving press-fit fittings and pipes. When installing, ensure that all components are from the same press-fit system and that the correct tooling is available. No additional accessories are required unless specified in the system design.

Technical background for designers

The O-ring functions as a dynamic seal between the pipe and fitting. Made from a rubber compound suitable for low-temperature environments, it maintains flexibility even at -20°C. The sealing mechanism relies on radial compression of the O-ring within the fitting. The material properties of the O-ring and the design of the press-fit socket determine the long-term performance of the connection. Factors such as media compatibility, installation quality, and operating conditions directly influence the service life of the seal.

Service and operation

No regular maintenance is required for this component during normal operation. However, periodic visual inspections should be carried out to detect signs of wear, deformation, or leakage. If the system is exposed to aggressive media or extreme temperatures beyond the specified range, the O-ring should be replaced. There are no defined service intervals provided in the technical data.

Frequently asked questions

Can this O-ring be used with compressed air systems?
Yes, it is suitable for compressed air applications as long as the operating pressure does not exceed PN10 and the temperature remains within the specified range.

Is this O-ring compatible with stainless steel press-fit fittings?
Yes, provided the fitting is designed for use with an O-ring of the same dimensions and material properties.

Can the O-ring be reused after removal?
No, once removed or compressed, the O-ring should not be reused as its sealing properties may be compromised.

What tools are required for installation?
A compatible press-fit tool is required to compress the fitting around the pipe and O-ring. Ensure the tool is calibrated according to the manufacturer's specifications.
