RTV (room temperature vulcanizing) silicone cures on exposure to moisture in the air, forming a flexible, durable seal that resists vibration, temperature cycling, and fluid exposure. This product is sold as a single unit and is suited for use by HVAC technicians, plumbers, and mechanical contractors who need a reliable, flexible sealant for metal-to-metal, metal-to-glass, and similar substrate joints.\u003c\/p\u003e\u003cp\u003eThis black silicone sealant is commonly used in residential and light commercial applications including duct sealing, equipment housing gaskets, drain pan repairs, and accessory mounting. Its black color makes it appropriate for visible joints where aesthetics matter or where high-heat environments such as flue surrounds or exhaust components require a dark finish. Technicians apply it when a compressible, waterproof seal is needed that can flex with thermal expansion and contraction over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBlack RTV silicone formula cures at room temperature without heat or special equipment\u003c\/li\u003e\n\u003cli\u003eFlexible cure resists cracking from vibration and thermal cycling\u003c\/li\u003e\n\u003cli\u003eAdheres to metal, glass, ceramic, and most plastics\u003c\/li\u003e\n\u003cli\u003eWaterproof seal suitable for drain, condensate, and moisture-exposed joints\u003c\/li\u003e\n\u003cli\u003eSold individually, minimum order quantity of 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose RTV silicone sealant for use in HVAC, plumbing, and mechanical assembly applications where a flexible, moisture-resistant bond is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eApplication should be made to clean, dry, oil-free surfaces for proper adhesion. Allow full cure time before exposing the joint to fluids or pressure. When used in HVAC or mechanical systems, follow applicable codes and manufacturer guidelines for sealant use on pressurized or gas-adjacent components. Wear appropriate PPE and ensure adequate ventilation during application, as acetic acid off-gassing is typical during RTV cure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: RTV Silicone Adhesive Sealant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 079340593756\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: LOC59375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCTITE","offers":[{"title":"Default Title","offer_id":51347269517618,"sku":"LOC59375","price":339.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310504619.jpg?v=1782100764","url":"https:\/\/voomisupply.com\/products\/loctite-loc59375-black-rtv-silicone-sealant","provider":"Voomi Supply","version":"1.0","type":"link"}
