Dow Corning 4097353 Rtv Silicone Joint Sealant 3.04 Oz

Product Description

The DOW CORNING 4097353 is a white RTV silicone joint sealant packaged in a 3.04 oz tube, designed for sealing joints and connections in HVAC, plumbing, and general mechanical applications. It cures at room temperature and reaches a tack-free state in 14 minutes, with full cure achieved in 24 hours. The silicone formulation handles an operating temperature range of -85 degrees F to 500 degrees F, making it suitable for high-heat environments such as flue connections, ductwork seams, and exhaust system joints. HVAC technicians, plumbers, and pipefitters commonly use this product for air-tight and weather-resistant sealing tasks.

This sealant is well suited for residential and light commercial HVAC applications, including sealing around duct penetrations, pipe chases, and mechanical enclosures. The white color makes it appropriate for visible interior joints where a clean finish is expected. The compact 3.04 oz tube format works well for field service calls and smaller repair jobs where full-cartridge quantities are unnecessary.

Installation Notes

Apply to clean, dry surfaces free of oil, grease, and loose debris for best adhesion. HVAC technicians and plumbers should follow local mechanical codes and manufacturer guidelines when using sealants on pressurized or flue-connected joints. Allow the sealant to reach full cure before restoring system pressure or airflow. Avoid disturbing the joint during the tack-free and curing periods.
