Suitable for plumbing and HVAC systems where durable, oil- and heat-resistant sealing is needed; sold by part number 459420.

## Long description

Sealing element VIEGA 28 x 3.1 mm FKM is an elastomer sealing ring made from fluorocarbon rubber (FKM) intended as a replacement or spare part for compatible pipe fittings and connectors. With a nominal cross-section of 28 x 3.1 mm, this sealing element provides a compact sealing profile that combines chemical resistance and temperature stability for use in plumbing and HVAC installations where durable, oil- and heat-resistant sealing is required.
Advantages
The FKM material offers high resistance to oils, fuels, many chemicals and elevated temperatures, reducing the risk of swelling or degradation in aggressive environments. Its dimensional stability and elastic recovery help maintain a reliable seal under pressure cycles and thermal changes. The compact 28 x 3.1 mm profile is designed for straightforward replacement, minimizing downtime when servicing fittings.
Suitable for
 Sealing joints in plumbing systems that encounter oils or aggressive media
 HVAC connections exposed to higher temperatures
 Replacement sealing rings in compatible fittings and couplings
 Applications requiring a compact, oil-resistant sealing element
Key specifications
 Material: FKM (fluorocarbon rubber) for chemical and heat resistance
 Nominal size: 28 x 3.1 mm (cross-section/profile dimensions)
 Shape: ring-type sealing element suitable for static and limited dynamic joints
 Properties: oil resistant, fuel resistant, good dimensional stability at elevated temperatures
How to use
Before installation, inspect the sealing seat and mating surfaces for damage, dirt or burrs and clean thoroughly. Check the new FKM sealing element for any visible defects. Fit the sealing ring into the groove or seat of the fitting, ensuring it sits evenly without twists or pinching. Reassemble the connection according to the fitting manufacturer's instructions and tighten to the recommended torque to achieve a secure seal. After installation, test the joint under working pressure and temperature conditions to confirm leak-free performance.
Usage recommendations
Store the sealing element in a cool, dry place away from direct sunlight and ozone sources. Avoid contact with strong bases or certain chemicals not compatible with FKM. For long-term reliability, replace seals during routine maintenance intervals or when signs of hardening, cracking or permanent deformation are observed.
