INSTRUCTIONS FOR USE
Activator: Make sure all working surfaces are clean and all grease has been wiped away. Apply enough TUFF-GEL to thread area to fill all engaged threads except for the first thread, which is to be kept free of the sealant. Thin, smaller bond gaps will allow for maximum performance. Allow at least 24 hours for full cure before filling and pressurizing the system.

STORAGE
TUFF-GEL should be stored in a cool, dry place at a temperature between 10 to 30^oC in original sealed container. Shelf life may be extended with refrigeration. Do Not Freeze.

NOTE:

TUFF-GEL is not recommended for use in pure oxygen or oxygen rich systems and should not be used as a sealant for strong oxidizing agents such as chlorine.
