Lockfast H42 Hydraulic Sealant is a brown, medium strength oil resistant pipe sealant. It is designed for the sealing and locking of metal fittings and pipes, typically in hydraulic systems. Recommended for fine-threaded fittings and parallel pipes up to 20mm. H42 prevents rust, corrosion and leakage as well as loosening from vibration or shock.
1. For optimum performance surfaces should be clean and free of grease.
2. If the material is an inactive metal consider using activator.
3. Shake the product thoroughly before use. Apply several drops to parts to be locked and sealed.
4. Assemble and tighten as required.
5. To prevent the clogging of the nozzle, do not let the tip touch metal surface during application.
There may be a difference in fixture speed and strength based on the substrate. As opposed to passive materials such as stainless steel or zinc dichromate, anaerobic adhesives will reach full strength more rapidly with active materials such as mild steel and brass.
For more information on strength of bond and cure time, please see the Lockfast gasketing and pipe sealants technical information sheet.
Remove with standard hand tools. In circumstances where hand tools do not work, use localised heat, disassemble while hot. To remove cured product use a combination of solvent and abrasion such as a wire brush.
