Material Compatibility
Dissimilar Metals
Installations containing mixed metals should generally be avoided, as galvanic corrosion may occur where different metals are connected directly together.
Where mixed-metal systems are unavoidable:
- Follow the Gas Safety (Installation and Use) Regulations 1998.
- Apply recognised engineering best practice.
- Consider suitable isolation measures where required.
1. PREPARATION:
• Ensure the O-ring is present & is seated correctly (not loose in the fitting).
• Cut the tube square.
2. TUBE PREPARATION:
• Check the tube ends are not damaged.
• De-burr the end of the tube.
• Ensure no sharp edges or swarf are present.
3. INSERTION AND DEPTH MARKING:
• Insert the tube into the fitting using a “twisting motion”.
• Using a permanent pen place a mark on the tube to indicate that the fitting is fully engaged.
• When all tubes are inserted double check the “depth marks” are in the correct position.
4. PRESS THE JOINT:
• Ensure the correct tool and jaws are selected.
• Place the jaw around the “bead” of the fitting.
• When correctly located press the trigger button to commence the pressing process.
• The tool will automatically stop when this is complete.
• Remove the pressed assembly from the jaw.
