It uses a patented adhesion system that delivers outstanding flexibility along with superior oil resistance, so the seal stays flexible and intact rather than hardening and cracking over time. The formula is sensor-safe, non-corrosive, and low-odor, meeting OE silicone gasket specifications, which makes it suitable for use around oxygen sensors and other sensitive automotive electronics without risking damage or false readings.\u003c\/p\u003e\u003cp\u003eThis gasket maker is designed for sealing timing covers, transmission pans, and oil pans, where a durable, oil-resistant seal is essential to prevent leaks under ongoing thermal cycling and engine vibration. Because it resists automotive fluids and shop chemicals in addition to oil, it holds up in the harsh under-hood environment where lesser sealants break down. The black color matches OEM gasket material for a factory-correct appearance on visible engine components.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Permatex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 82180\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormula:\u003c\/strong\u003e RTV silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOdor Level:\u003c\/strong\u003e Low odor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Safe:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Properties:\u003c\/strong\u003e Non-corrosive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is Permatex Ultra Black RTV Silicone Gasket Maker used for?\u003c\/strong\u003e Permatex Ultra Black (part number 82180) is used to seal timing covers, transmission pans, and oil pans where strong adhesion and oil resistance are required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this gasket maker safe to use near oxygen sensors?\u003c\/strong\u003e Yes, Permatex Ultra Black uses a sensor-safe formula, meaning it will not damage oxygen sensors or cause false sensor readings when used on nearby sealing surfaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the tube of Permatex Ultra Black weigh?\u003c\/strong\u003e The 3 oz tube of Permatex Ultra Black RTV Silicone Gasket Maker, part number 82180, weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Permatex Ultra Black resist oil and other automotive fluids?\u003c\/strong\u003e Yes, this RTV silicone formula offers superior oil resistance and also resists automotive fluids and shop chemicals, which helps it hold up under harsh under-hood conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this sealant hold up to engine vibration?\u003c\/strong\u003e Permatex Ultra Black is formulated to resist vibration, using a patented adhesion system that maintains high flexibility so the seal does not crack or loosen over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Permatex Ultra Black corrosive to engine components?\u003c\/strong\u003e No, part number 82180 uses a non-corrosive formula, making it safe for contact with metal engine surfaces during and after curing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket maker have a strong odor?\u003c\/strong\u003e Permatex Ultra Black is a low-odor formula, which is more comfortable to work with during application compared to stronger-smelling sealants.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size tube does Permatex Ultra Black come in?\u003c\/strong\u003e This product is packaged as a 3 oz tube, listed under Permatex part number 82180.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Permatex Ultra Black meet OE gasket specifications?\u003c\/strong\u003e Yes, the formula in part number 82180 meets OE silicone gasket specs, making it suitable for original-equipment-level sealing performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat surfaces is Permatex Ultra Black best suited for?\u003c\/strong\u003e It is designed for sealing applications requiring strong adhesion and high performance under exposure to oils and vibration, such as timing covers, transmission pans, and oil pans.\u003c\/p\u003e","brand":"Permatex","offers":[{"title":"Default Title","offer_id":49028203675867,"sku":"PER-82180","price":7.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/PER-82180__57144.1747363874.500.750.jpg?v=1785165311","url":"https:\/\/www.goodvibesmarina.com\/products\/permatex-ultra-black-rtv-silicone-gasket-maker-3-oz-sensor-safe-non-corrosive-formula","provider":"Good Vibes Marina","version":"1.0","type":"link"}
