Frequently Asked Questions

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

A traditional gasket is a pre-formed piece of material (rubber, cork, metal) designed to fit between two surfaces. RTV (Room Temperature Vulcanizing) sealant is a liquid silicone compound that cures into a flexible rubber seal, often used to fill gaps, seal uneven surfaces, or replace conventional gaskets entirely in specific applications.

How long does RTV gasket maker take to cure?

Most RTV sealants, like Permatex Ultra Blue, skin over in about 10-15 minutes and become tack-free in an hour. However, they typically require 24 hours to achieve full cure strength and temperature resistance. It is crucial to allow the full cure time before exposing the seal to fluids or high temperatures.

Why do exhaust gaskets fail frequently in performance vehicles?

Exhaust gaskets fail due to extreme temperature cycling, high vibration, and pressure pulses. Performance vehicles often run hotter and experience greater stress. Using reinforced materials like graphite or MLS (Multi-Layer Steel) gaskets designed specifically for high-heat applications is necessary to prevent premature failure.

Are 'universal' gaskets reliable for small business use?

While RTV sealants offer high versatility, pre-cut 'universal' gaskets (like exhaust flanges) should be carefully checked for size and material compatibility. For critical engine components (head gaskets, intake manifolds), always use application-specific, high-quality gaskets like those from FEL-PRO to ensure proper sealing and performance.
