It cures to a tough, flexible, rubbery solid when exposed to ambient moisture in the air. Designed for HVAC applications, it forms a weatherproof, durable seal on ductwork, pipes, vents, and fixtures across a temperature range of 35 to 140 degrees F. The paste consistency allows for easy tooling and gap-filling on both flat and irregular surfaces. It is VOC compliant and manufactured in the USA. HVAC technicians, plumbers, and sheet metal contractors reach for this product when sealing leaks or gaps in heating, ventilating, and air conditioning systems.\u003c\/p\u003e\n\u003cp\u003eThe 37002 is suited for residential and light commercial HVAC installations where a reliable, flexible sealant is required. It adheres to a wide range of substrate types, making it useful for sealing around duct joints, pipe penetrations, vent collars, and fixture gaps. It performs on glass, metal, wood, ceramic, plastic, and silicone resin surfaces, which makes it versatile across multiple trade applications beyond duct sealing alone. Fast cure time supports efficient job-site workflow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-component acetoxy silicone formula cures on exposure to air moisture — no mixing required\u003c\/li\u003e\n  \u003cli\u003eTemperature-rated from 35 to 140 degrees F for HVAC system environments\u003c\/li\u003e\n  \u003cli\u003eAdheres to metal, glass, wood, ceramic, plastic, and silicone resin surfaces\u003c\/li\u003e\n  \u003cli\u003eWeatherproof seal resists moisture intrusion around ducts, pipes, vents, and fixtures\u003c\/li\u003e\n  \u003cli\u003eVOC compliant formulation meets applicable regulatory requirements\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM C-920-86, TT-S-001543A, TT-S-00230C, and ISO standards\u003c\/li\u003e\n  \u003cli\u003eMade in USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on HVAC ductwork, pipe penetrations, vents, and fixtures.
