The Tube Expander Tool Spacer acts as a spacing aid, controlling the depth and alignment of the expander tool when inserted into tubes. By keeping a consistent offset, the spacer ensures uniform expansion results across multiple tubes, reducing variation in repeated operations. It supports stable tool positioning and helps prevent over-expansion or uneven contact inside the tube, enabling reliable and smooth handling during tube fitting tasks.Attributes:• Controls expansion depth for accurate tube fitting.• Maintains accurate axial alignment of the expander tool.• Supports repeatable expansion results across multiple tubes.• Reduces the chance of uneven tube expansion.Applications: The Tube Expander Tool Spacer is used with a tube expander tool to control spacing and alignment during tube expansion, helping achieve proper fitting and secure tube connections during service and maintenance tasks.
