Understanding HVAC Couplings: White Vs. Black.
Small installation details can make a big difference in high-velocity HVAC systems.
In this video, we take a closer look at how white and black couplings are typically used in different applications. White couplings are commonly used for ceiling connections, while black couplings are typically used for floor connections.
When connecting a coupling to a takeoff, the color does not determine the connection. The key detail is the gasket: each coupling connection should have one gasket, and no more than one.
At Cobalt Creed, we believe understanding the details behind HVAC installation helps create more consistent and reliable systems.
