Instructions for Use

Ensure parts are clean, dry and free from oil and grease. Vibra-Tite Hot-lock relies on the evaporation of water to build strength. Use in a sealed joint will require heating to reach a functional strength. Temperature exposure over 230°F (110℃) will greatly accelerate fixture time.
