Customer Questions & Answers
-
Question:
What is Permatex 22071 used for?
Answer: Permatex 22071 is specifically designed for sealing water pumps and thermostats. Its RTV silicone formulation allows it to withstand high temperatures and pressure, making it ideal for automotive applications. It is particularly useful in preventing leaks in engines where water pumps or thermostats are involved. This product allows for strong adhesion to multiple surfaces, including metal and plastic, ensuring long-lasting seals. -
Question:
How do I apply the Permatex RTV Silicone Gasket?
Answer: To apply the Permatex RTV Silicone Gasket, start with a clean and dry surface. Squeeze a bead of silicone directly onto the surface where the gasket is needed. Use a tool or your finger to spread it to an even thickness, covering the entire area. Allow it to cure for the recommended time before adding any further parts, ensuring a solid, leak-proof seal for your water pump or thermostat. -
Question:
Is the silicone gasket resistant to temperature and automotive fluids?
Answer: Yes, Permatex 22071 RTV Silicone Gasket exhibits excellent resistance to both high temperatures and various automotive fluids. It can endure extreme thermal variations found in engine components without breaking down, which is essential for maintaining an effective seal. This feature makes it suitable for use in demanding environments where conventional gaskets may fail, thereby enhancing the longevity and performance of your vehicle's cooling system. -
Question:
Can I use this product on plastic surfaces?
Answer: Absolutely! Permatex 22071 is versatile enough to bond with both metal and plastic surfaces. Its advanced formula creates a strong, flexible seal that accommodates the expansion and contraction typically experienced in automotive environments. This property is especially beneficial when working with plastic components, as it minimizes the risk of cracking or damaging them during installation. -
Question:
How long does it take for the Permatex gasket to cure?
Answer: The curing time for Permatex 22071 depends on environmental conditions, typically ranging from 24 hours to several days for full strength. However, it becomes tack-free usually within a few hours. It's crucial to allow adequate time for the gasket to set before subjecting it to pressure or fluid, ensuring that it forms a reliable, leak-proof barrier that will last. -
Question:
Can the silicone be painted over?
Answer: Yes, after the Permatex RTV Silicone Gasket has fully cured, it can be painted over. Make sure the surface is clean, and test a small area first to ensure compatibility with your chosen paint. This flexibility allows for aesthetic customization if the gasket is visible, enhancing the overall look of your engine compartment. -
Question:
Is Permatex 22071 suitable for use on marine engines?
Answer: While Permatex 22071 is primarily designed for automotive applications, it can be used in certain marine engine applications due to its resistance to oil and water. However, it's always best to consult your engine's manual or a professional to ensure compatibility with marine conditions, including exposure to saltwater, which may affect seal integrity over time. -
Question:
What color does the Permatex 22071 silicone come in?
Answer: Permatex 22071 RTV Silicone Gasket comes in a striking blue color. This not only distinguishes it for easy identification during application but is also indicative of its advanced formulation. The blue hue can help you see where you have applied the product, ensuring even coverage and proper application on the necessary surfaces. -
