What Are HVAC Gaskets?
HVAC gaskets are specialised sealing components used in heating, ventilation, and air conditioning systems to ensure an airtight or watertight seal between connected parts.
Key Features of HVAC Gaskets
- Material Versatility: Made from rubber, foam, silicone, neoprene, and cork, depending on the specific application and temperature range.
- Temperature Resistance: Designed to withstand extreme temperatures, making them suitable for both heating and cooling systems.
- Durability: Engineered to handle pressure fluctuations, vibrations, and exposure to chemicals without degradation.
- Energy Efficiency: Prevents air leakage to improve HVAC system performance and reduce energy consumption.
- Noise Reduction: Acts as a dampener to minimise vibrations and reduce noise in HVAC systems.
