Permatex Ultra Black RTV is a good choice for oil pan gaskets
The temperature range of the Permatex Ultra Black RTV is -65°F to 500°F (-54°C to 260°C) intermittently. It is resistant to auto and shop fluids, as well as vibration. This product is designed to be used in areas where you need flexible and oil-resistant silicone gaskets, such as oil pans, timing covers, transmission pans, and differential covers.
When applying Permatex Ultra Black RTV, it is recommended to clean and dry all surfaces with a residue-free solvent, such as Permatex Brake & Parts Cleaner. A continuous and even bead of silicone should be applied to one surface, surrounding all bolt holes. Finger-tighten the bolts until the material begins to squeeze out, then allow it to dry for one hour before retightening. The silicone will fully cure in 24 hours, although this time may be longer in cold or very dry conditions.
Permatex Ultra Black RTV has received positive reviews from customers, who have found it to be reliable, long-lasting, and effective in preventing leaks. It is also easy to apply and provides a good seal.

Gaskets should be cleaned with a solvent before applying Permatex
Gaskets should always be cleaned with a solvent before applying Permatex. This is because old gasket material, gasket maker residue, and other contaminants can compromise the seal and the operation of the assembly. A proper cleaning ensures that the mating surfaces come together evenly and creates an optimal condition for the Permatex to adhere.
Permatex offers a range of gasket removers and cleaners that are ideal for this purpose. For instance, the Permatex Gasket Remover is a powerful product with a built-in brush-tip that facilitates easy application and scrubbing on intricate surfaces. It quickly penetrates and removes stubborn or baked-on solvent-based gaskets, gasket maker residue, and gasket sealant products. It is recommended to follow the directions for use on the product packaging for optimal results.
Additionally, when preparing the surface, it is crucial to use the right tools to avoid damaging the metal surfaces. Plastic scrapers or nylon brushes are ideal for removing old gaskets, as they effectively remove the material without scratching the metal. Chemical gasket removers can also be used to ensure a thorough cleaning.
By cleaning the gaskets with a solvent prior to applying Permatex, you can be confident that the mating surfaces are properly prepared, free from contaminants, and ready for the new gasket installation. This crucial step helps ensure a successful repair and prevents potential leaks.

Permatex Ultra Copper RTV is good for dissimilar metal contact
When it comes to oil pan gaskets, choosing the right Permatex product is essential to ensure a reliable and long-lasting seal. While there are various types of Permatex products available, Permatex Ultra Copper RTV stands out as an excellent choice for several reasons, especially when it comes to dissimilar metal contact.
Firstly, Permatex Ultra Copper RTV is specifically designed for high-temperature applications, with a temperature range of -65°F to 700°F (-54°C to 371°C) intermittently. This makes it ideal for oil pan gaskets, as they often operate in high-temperature environments. The product has been tested to exceed OEM specifications, ensuring its reliability and performance.
Secondly, Ultra Copper RTV is sensor-safe, low odor, and non-corrosive. This means it won't interfere with any sensors in the assembly and won't cause unpleasant odors or corrosion issues. This is particularly important when dealing with dissimilar metals, as some metals are more susceptible to corrosion than others.
Thirdly, Ultra Copper RTV offers excellent resistance to auto and shop fluids, as well as vibration. This is crucial for oil pan gaskets, as they are constantly exposed to fluids and vibration from the engine. The product can flex to accommodate the different expansion and contraction rates of dissimilar metals, ensuring a strong and durable seal.
Additionally, Ultra Copper RTV is suitable for applications where pressure builds up, such as turbocharger applications and exhaust systems. Its high-temperature resistance and ability to withstand pressure make it a top choice for high-performance engines.
When using Ultra Copper RTV, it's important to follow the manufacturer's instructions for proper application. Ensure that all old gasket material, oils, and fluids are removed before applying the product. Unlike some other gasket makers, Ultra Copper RTV does not require smoothing out before installing, as this can create peaks and valleys that affect the evenness of the application.
In summary, Permatex Ultra Copper RTV is an excellent choice for oil pan gaskets, especially when dealing with dissimilar metal contact. Its high-temperature resistance, sensor-safe and non-corrosive formula, fluid and vibration resistance, and flexibility make it a reliable and durable solution for creating strong seals between dissimilar metals.
