Sealing and Cushioning in HVAC Systems
HVAC equipment contains multiple metal panels, ducts, access doors and internal components. Small gaps may lead to air leakage, vibration noise or contact between metal parts.
EPDM foam rubber can provide sealing, cushioning and vibration reduction within HVAC equipment and ventilation systems.
Common HVAC Applications
EPDM foam products are commonly used around:
- Access panels
- Equipment housings
- Duct connections
- Fan assemblies
- Ventilation covers
- Air-handling units
- Metal frame joints
The material can help reduce direct contact between connected components while maintaining flexible sealing pressure.
Product Options
Depending on the application, OKIN can supply:
- EPDM foam strips
- Die-cut foam pads
- Adhesive-backed foam tapes
- Custom foam gaskets
- Continuous sealing rolls
- Pre-cut assembly components
For complex panel shapes, die-cut gaskets can reduce manual cutting and improve assembly consistency.
Material Selection
Important factors include:
- Operating temperature
- Compression space
- Air-sealing requirement
- Vibration level
- Foam thickness
- Density and recovery
- Adhesive surface condition
Prototype samples should be tested in the actual HVAC assembly to confirm fit, compression and installation performance.
