Packaged in an 8 oz tube for easy direct application, this sealant cures at room temperature within 24 hours and maintains performance from -30 degrees F up to 450 degrees F. It is used by HVAC technicians, electricians, plumbers, and automotive professionals who need a reliable, moisture-resistant sealant for joints, gaskets, vents, and electrical enclosures. The flexible cured bead resists cracking and vibration over repeated thermal cycles.\u003c\/p\u003e\n\u003cp\u003eThis RTV silicone sealant is suited for residential and commercial applications where a flexible, long-lasting seal is required. Common uses include automotive gasket forming, electrical junction sealing, HVAC vent connections, insulating applications, and wall joint sealing. It is well suited for any trade scenario where temperature extremes, moisture exposure, or mechanical vibration would compromise a rigid sealant. The 8 oz tube format allows controlled dispensing without a caulking gun, making it convenient for service calls and bench repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOperating temperature range: -30 degrees F to 450 degrees F for high-heat environments\u003c\/li\u003e\n  \u003cli\u003eFull room-temperature cure in 24 hours — no oven or UV curing required\u003c\/li\u003e\n  \u003cli\u003eBlack color suits gasket and automotive applications where appearance matters\u003c\/li\u003e\n  \u003cli\u003e8 oz tube format allows direct application without additional tooling\u003c\/li\u003e\n  \u003cli\u003eFlexible cured bead resists cracking under vibration and thermal cycling\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM C-920, TT-S-001543A Class A, and TT-S-00230C Class A standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in automotive, electrical, gasket, insulating, vent, and wall joint applications where an RTV silicone elastic sealant is specified.

Apply a continuous bead and allow a full 24-hour cure before exposing the joint to fluids or mechanical stress. Electricians and HVAC technicians should verify that the sealant is fully cured before restoring power or airflow to the sealed assembly. Work in a well-ventilated area during application, as acetic acid vapors are released during cure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical Type\u003c\/strong\u003e: RTV Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Elastic Sealant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 8 oz\u003c\/li\u003e\n  \u003cstrong\u003eContainer Type\u003c\/strong\u003e: Tube\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -30 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Cure Time\u003c\/strong\u003e: 24 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM C-920, TT-S-001543A Class A, TT-S-00230C Class A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Automotive, Electrical, Gasket, Insulating, Vents, Wall Joints\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: CRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1004799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRC INDUSTRIES","offers":[{"title":"Default Title","offer_id":51699990528306,"sku":"1004799","price":56.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/774ab5bf470debdae9e29dc0df198d13.jpg?v=1788384634","url":"https:\/\/voomisupply.com\/products\/crc-1004799-rtv-silicone-elastic-sealant-8-oz-black","provider":"Voomi Supply","version":"1.0","type":"link"}
