What is an HVAC Gasket?

The role of an HVAC gasket is to form a secure seal around key components, facilitating effective temperature control and offering protection to the system's parts.

What is the Difference Between a Seal and a Gasket?

Seals and gaskets are essential for leak prevention but differ in their application. Gaskets are the go-to choice for sealing between flat surfaces that remain static, while seals are specifically designed for parts with motion, like motors and pumps, accommodating their movement and providing a tight fit.

What Type of Gasket is Used in Ductwork?

Duct gaskets are crafted from a variety of materials such as neoprene, vinyl nitrile, sturdy EPDM, and flexible butyl, offering a range of sealing capabilities. Many of these gaskets come with an adhesive backing, enhancing their ability to tightly seal ductwork and improve efficiency.
