How to

Step by Step Guide

1. Preparation

Cleaning - It is recommended to use LOCTITE® 7063 to degrease and clean surfaces prior to applying adhesive. Activation - If cure speed is too slow due to passive metals (stainless steel, aluminium and plated metals) or low temperatures (below 5°C), use activator LOCTITE® 7240 or LOCTITE® 7649 (see cure speed vs activator graph in the TDS).

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. (Recommended dispensing equipment: IDH 608996 50ml Hand Pump or IDH 88631 Peristaltic handgun 97001)

3. Assembly

Assemble fittings using wrench tightening in accordance with manufacturers' recommendations.

4. Disassembly

Disassemble with standard hand tools. If not possible, apply localised heat to approximately 250°C; disassemble while hot. For corroded or seized parts use LOCTITE® 8040 Freeze and Release.
