Mastercool 71500-A Hydra-Krimp A/C Hose Crimping System

The Mastercool 71500-A Hydra-Krimp A/C Hose Crimping System provides technicians with a fast, reliable way to assemble and repair automotive A/C hoses using controlled hydraulic force. Because the tool generates high crimping pressure with minimal pumping effort, it produces uniform, repeatable crimps while reducing physical strain.

This Hydra-Krimp system supports both standard and reduced-barrier A/C hoses commonly used in mobile air conditioning systems. As a result, technicians can fabricate secure, leak-resistant hose assemblies directly on the vehicle or at the workbench. In addition, the six-segment die design creates an OE-style crimp that promotes even compression around the fitting.

The lightweight, hand-held hydraulic body makes the 71500-A ideal for both shop and field applications. Dies snap quickly into the press fixture without pins or screws, which improves efficiency during repetitive hose work. The system comes housed in a custom molded case, helping protect components during transport and storage.
