ωτ Functions of Heat Blocking Gel:

1. Protects Components from Heat During Welding / Brazing
• Used when heating copper pipes with a torch (brazing/welding).
• Applying heat blocking gel prevents heat from spreading to other sensitive parts such as:
• Valves
• Service ports
• O-rings
• Plastic or rubber components

.;

2. Prevents Damage from Overheating
• Without heat protection during brazing, heat can damage:
• Melted O-rings
• Damaged valves
• Burnt or melted insulation
• Burned PCB (if too close)
• This gel absorbs and resists high temperatures, up to over 2000°F (1100°C) depending on the brand.

.;

3. Safe & Non-Corrosive
• Does not corrode metals or pipes.
• Leaves no chemical residue – can be wiped clean with water after use.

.;

4. Reusable
• Most heat blocking gels can be reused after the job is done.
• Example: jelly-like texture, can be collected and stored back in its container.

How to Use Heat Blocking Gel:
    1.    Apply a thick layer of gel to the area that needs protection (around joints, valves, or plastic parts).
    2.    Ensure the sensitive area is fully covered.
    3.    Carry out brazing as usual.
    4.    After finishing, wipe the gel with a damp cloth or rinse with water.
