Description

EPDM Rubber Gasket Seals for HVAC

The EPDM Rubber Gasket Seal for HVAC is specifically designed to provide reliable air and water tightness in heating, ventilation, and air conditioning (HVAC) systems. Manufactured from high-performance EPDM rubber, these gaskets are precision-molded for dimensional stability, exceptional resilience, and long-term sealing performance. Their smooth, glossy surface finish ensures minimal friction during installation and operation, making them ideal for both OEM and replacement applications.

Key Performance Features

  • Superior Air & Water Sealing: Effectively prevents leakage and loss of conditioned air, enhancing HVAC system efficiency.
  • Excellent Weather, UV, and Ozone Resistance: Suitable for indoor and outdoor applications, resistant to aging, cracking, and hardening.
  • High Elastic Recovery: Maintains tight seal under compression, even after repeated cycles and long-term use.
  • Wide Temperature Range: Functional from -40°C to +120°C, ensuring consistent sealing in all climate zones.
  • Non-Conductive & Insulating: Provides electrical insulation for enhanced safety in HVAC installations.

Main Advantages

  • Custom Profiles & Sizes: Available in round, square, and custom cross-sections for compatibility with different flanges, ducts, and panel connections.
  • Low Installation Friction: Smooth surface finish for easy fitment and reduced risk of gasket displacement.
  • Long Service Life: Resists deformation and compression set for long-term sealing without maintenance.
  • Environmentally Safe: Halogen-free, non-toxic, compliant with RoHS/REACH directives.
