## Long description

The SANHA FKM O-ring seal with dimensions of 28.30 x 3.10 mm is a specialized sealing component engineered for high-performance solar thermal installations. Constructed from durable fluoroelastomer (FKM), this seal provides exceptional thermal stability and chemical resistance, making it a critical element for maintaining the long-term integrity of solar heating circuits. Its precise design ensures a secure, leak-proof connection that withstands the rigorous operating conditions typical of solar energy systems.
Advantages
This FKM O-ring offers superior resistance to the high temperatures and aggressive heat transfer fluids commonly found in solar thermal systems. Unlike standard rubber seals, the fluoroelastomer material maintains its elasticity and sealing properties over extended periods, preventing premature degradation and leaks. By choosing this high-quality component, users ensure the continued efficiency and safety of their solar installations, reducing the need for frequent maintenance and minimizing the risk of system downtime.
Suitable for
Solar thermal heating systems
High-temperature fluid transfer applications
Replacement of worn seals in compatible pipe fittings
When it may not be suitable
This seal is specifically dimensioned for compatible pipe fittings and may not fit systems requiring different diameters or thicknesses. It is not intended for use in applications involving incompatible chemicals or extreme pressures that exceed the specified material ratings for fluoroelastomer.
Key specifications
Material: FKM (Fluoroelastomer)
Dimensions: 28.30 mm x 3.10 mm
Application: Solar thermal systems
Resistance: High temperature and chemical exposure
How to use
To install the seal, ensure the pipe fitting surface is clean, dry, and free of debris or old residue. Carefully seat the O-ring into the designated groove of the fitting, ensuring it is not twisted or pinched during assembly. Once positioned, complete the connection according to the manufacturer's installation guidelines for the specific pipe system to ensure a uniform seal.
What to consider before purchase
Verify the exact dimensions required for your specific pipe fitting
Ensure compatibility with the heat transfer fluid used in your system
Check the condition of the fitting groove before installation
Usage recommendations
Regularly inspect the sealing points of your solar system during annual maintenance to ensure the O-ring remains in optimal condition and to prevent potential leaks before they occur.
