Precision expansion for copper lines
The workshop bench often demands tools that are as precise as they are portable. This silver-finished expander sits comfortably in the hand, its compact form factor ensuring it does not clutter the workspace when not in active use.
Designed for technicians working on air conditioning and refrigeration systems, this manual press expands copper tubing without the need for external power. It suits professionals who value control and durability in their daily routine.
02MATERIALS
Aluminum alloy meets hardened steel
The body is forged from high-hardness aluminum alloy, providing a lightweight yet robust frame that resists wear over time. The expansion tube head itself is machined from 45# steel, offering the necessary rigidity to deform copper consistently. This combination ensures the tool remains sharp and functional through repeated cycles of pressure.
04FUNCTION
Manual pressure for controlled results
Operating via a manual press mechanism, the tool relies on the user’s force rather than pneumatic or electric power. This direct connection provides immediate feedback on resistance, allowing for subtle adjustments. It is ideal for expanding copper pipes ranging from 6 to 22 millimetres in diameter, accommodating various line sizes found in HVAC units.
05DETAILS
Compact build with tail lock
Measuring approximately 15 by 15 centimetres, the tool is small enough to fit into a standard toolkit pocket. A dedicated tail lock design secures the components when not in use, preventing accidental opening and reducing the overall footprint. At roughly 375 grams, it is light enough for extended sessions without causing hand fatigue.
