Frequently Asked Questions
Q: Is this automotive gasket sealant safe to use around oxygen sensors?
A: Yes. The Axl Automotive Gasket Sealant is silicone-free, meaning it does not emit compounds that can contaminate or damage oxygen sensors — a common concern with standard silicone-based sealants. Its rubber-based, oxidation-hardening formula is safe for use in sensitive engine environments.
Q: What is the difference between the 50g and 85g sizes?
A: Both sizes contain the same high-temperature black sealant formula. The 50g tube is ideal for smaller, targeted repairs such as sealing a single gasket or addressing a minor oil leak. The 85g tube provides more material for larger repairs or multiple sealing jobs, offering better value for more extensive engine maintenance work.
Q: How long does this engine sealant take to cure?
A: The sealant uses an oxidation-hardening process, meaning it cures by reacting with air. Full cure time can vary depending on temperature and humidity conditions. For best results, allow the sealant to cure completely before starting the engine and exposing it to heat and fluids.
Q: Can this sealant be used to prevent oil leaks?
A: Yes. The Axl Automotive Gasket Sealant is specifically designed for car maintenance applications including oil leakage prevention. Its durable, high-temperature-resistant bond helps maintain effective seals around gaskets and engine components to keep fluids where they belong.
