Rubber Washers for HVAC Applications
HVAC systems rely on rubber washers for vibration dampening, sealing ductwork connections, and isolating equipment from mounting surfaces. The right washer material reduces noise, prevents leaks, and extends equipment life.
Best Materials for HVAC Washers
- Neoprene — The most common choice for HVAC. Excellent vibration dampening, good temperature range, and resistant to weathering for rooftop units.
- EPDM — Best for outdoor HVAC equipment exposed to UV and ozone. Also suitable for chilled water and steam applications.
Common HVAC Applications
- Fan and blower motor mounting (vibration isolation)
- Ductwork flange connections
- Rooftop unit mounting hardware
- Refrigerant line fittings
- Condensate drain connections
