How to
Step by Step Guide
1. Preparation
Cleaning - It is recommended to use LOCTITE® SF 7063/7064/7070 to degrease and clean surfaces prior to applying adhesive. Activation - If cure speed is too slow due to passive metals (stainless steel, aluminum and plated metals) or low temperature (below 5°C), apply activator LOCTITE® SF 7240 or LOCTITE® SF 7649 (see cure speed vs activator graph in the TDS). Allow to dry.
2. Application
Apply a 360° bead to the leading male thread, leaving the first thread free. For bigger threads, apply both on male and female threads. For manual dispensing the use of a peristaltic handgun is recommended to ensure a consistent application volume.
3. Assembly
Assemble fittings using wrench tightening in accordance with manufacturers' recommendations.
4. Disassembly
Disassemble with standard hand tools. If not possible, apply localized heat to approximately 500°F/260°C; disassemble parts while hot. For corroded or seized parts use LOCTITE® LB 8040 Freeze and Release.
