It cures at room temperature to form a tough, flexible rubber seal that resists heat, vibration, and moisture. Designed for use across HVAC, plumbing, electrical, and general mechanical service work, this red silicone sealant is the go-to choice for licensed tradespeople who need a reliable, durable seal in demanding environments. The red color indicates high-temperature suitability, making it appropriate for flues, vents, and exhaust-adjacent assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sealant is suited for both residential and light commercial applications. Typical uses include sealing ductwork joints, vent connections, flue penetrations, and door or window perimeters where a flexible, heat-resistant seal is required. It also performs well for protecting electrical leads from mechanical shock and providing basic electrical insulation around low-voltage connections. HVAC technicians, plumbers, and electricians routinely use this product during installation and service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-part RTV formula cures at room temperature without mixing or heat activation\u003c\/li\u003e\n  \u003cli\u003eRed color indicates high-temperature resistance suitable for flues, vents, and exhaust areas\u003c\/li\u003e\n  \u003cli\u003eForms a tough, flexible rubber seal that handles vibration and thermal cycling\u003c\/li\u003e\n  \u003cli\u003eProvides electrical insulation and protects leads from mechanical shock\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose adhesion to common substrates including metal, glass, and rigid plastics\u003c\/li\u003e\n  \u003cli\u003eSuitable for sealing ductwork, vents, flues, doors, windows, and trim\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose RTV silicone sealant for use on metal, glass, and similar substrates in HVAC, plumbing, and electrical applications where a flexible, high-temperature-rated seal is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis product is installed by licensed HVAC technicians, plumbers, and electricians as part of sealing and weatherproofing work. Before applying, ensure all surfaces are clean, dry, and free of grease, dust, or old sealant. Allow full cure time at room temperature before exposing the seal to heat or pressure. Refer to applicable codes such as the IFGC or IMC when using this sealant on flue or vent connections to confirm it meets the required temperature rating for the specific installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.273 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCure Method\u003c\/strong\u003e: Room temperature cure (RTV)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponents\u003c\/strong\u003e: One-part\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 079340596307\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LOCTITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LOC59630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCTITE","offers":[{"title":"Default Title","offer_id":51345537892658,"sku":"LOC59630","price":182.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310504406.jpg?v=1782060597","url":"https:\/\/voomisupply.com\/products\/loctite-loc59630-red-high-temp-rtv-silicone-sealant","provider":"Voomi Supply","version":"1.0","type":"link"}
