Frequently Asked Questions

What is the difference between RTV silicone and a traditional gasket?

RTV silicone (like Permatex) is a liquid sealant that cures into a durable, flexible, formed-in-place gasket, ideal for sealing covers and housings. Traditional gaskets are pre-cut components made from materials like composite, cork, or MLS steel, designed for specific mating surfaces like cylinder heads or intake manifolds.

Why are MLS gaskets preferred for performance engines?

MLS (Multi-Layer Steel) gaskets are preferred because they can withstand significantly higher cylinder pressures and temperatures than traditional composite gaskets. Their layered design allows for micro-movement between the block and head without compromising the seal, making them ideal for turbocharged, supercharged, or high-compression naturally aspirated engines.

How do I know which Permatex RTV to use?

Permatex offers different RTV types for specific needs. Ultra Black is known for maximum oil resistance and flexibility (ideal for oil pans/valve covers). Ultra Grey is designed for rigid, high-torque applications and high vibration (common in import engines). Always check the product description for temperature and fluid resistance.
