When stored correctly in a cool, dry place with the cap securely fastened, the sealant typically maintains its properties for up to two years.
While it resists heat, it is best suited for applications within typical engine operating temperatures. For extreme exhaust heat, specialized high-temperature sealants may be required.
The sealant is designed to remain flexible and does not 'cure' in the traditional sense. It allows for immediate assembly and function, but full sealing strength develops over a few hours as components are brought together.
The product information does not specify suitability for potable water systems. It is generally recommended for industrial, automotive, and heating applications.
The sealant is compatible with composite gaskets, which may include some plastics. However, always test on a small, inconspicuous area if unsure about compatibility with specific plastic types.
Due to its non-hardening nature, old sealant can often be wiped away with a rag. For stubborn residue, a plastic scraper or appropriate solvent (test compatibility first) may be used.
Ensure surfaces are thoroughly cleaned, dried, and free from contaminants like oil or dust. Reapply sealant after cleaning.
Check that the correct amount of sealant was applied and that parts were torqued to specification. Disassemble, clean, and reapply sealant if necessary.
Ensure the tube cap is fully removed. If partially hardened, carefully clear the nozzle. Store upright with the cap on tightly.
Setup: Ensure all surfaces to be sealed are clean, dry, and free from oil, grease, and old sealant. Apply a thin, even bead of the sealant to one surface or thread. Assemble the parts promptly, ensuring proper alignment. Tighten to the manufacturer's recommended torque specifications.
Compatibility: This sealant is compatible with metal, rubber, paper, and composite gaskets. It is resistant to fuel, oil, water, gas, and steam.
Care: Store the tube in a cool, dry place away from direct sunlight. Ensure the cap is securely fastened after each use to prevent the sealant from drying out. Clean up any excess sealant immediately with a damp cloth before it cures.
