💡 How does controlled radial force prevent compression set damage in soft metal refrigeration lines?
Managing consistent outward pressure stops wall thinning while maintaining structural integrity throughout the connection point.
- Gradual mandrel advancement distributes torque evenly across the contact surface
- Controlled deformation thickens the rolled edge to block freon migration pathways
- Precise dimensional tracking avoids cross threading issues on matching service ports
