Description
The York S1-304156 Duct Sealant is a sealing component used to close gaps, joints, and small openings in ducting HVAC systems where air leakage may occur during operation. It regulates by forming a pliable mass that adheres to metal surfaces and irregular contours and blocking unintended air escape points and reinforcing joint integrity. Applied across duct networks, fan casings, and air distribution assemblies, it is pressed into seams or connection edges to create a continuous sealing layer. The sealing action contributes to improved airflow retention and reduced leakage between joined sections, more stable air movement through connected ventilation routes.
