The FS-7842 series hydraulic A/C hose crimper is designed for quick, precise, and safe crimping of air conditioning and industrial hoses. With an 8T high-output hydraulic system and point-type hexagonal crimping, this tool ensures tight, secure, and reliable connections.
High-strength aluminum alloy construction with one-time molding and uniform heat treatment provides durability and prevents breakage. The latch uses thread locking technology to prevent accidental mold ejection, improving operational safety. The new oil leakage prevention technology with a double-layer piston seal ensures stable, tight crimps.
The FS-7842 features a straightforward, step-by-step installation and operation process: select the correct die, insert the pin, close the jaws, rotate the body, turn the valve to working position, and pump the handle until the crimping is complete. The clamp head can accommodate multiple dies (#6, #8, #10, #12, etc.) for versatile applications.
Packaged in a sturdy plastic box, the tool is easy to carry and store, making it ideal for on-site HVAC, automotive, industrial maintenance, and repair operations.
