The Kimball Midwest K300 Hydraulic Hose Crimper is a robust and user-friendly device designed for crimping hydraulic hoses. It boasts a powerful 62-ton hydraulic cylinder, capable of crimping a wide range of hoses: 1-1/4" 1-2 wire, 1-1/2" 4 wire, and 1" 6 wire.
Function Description:
The primary function of the K300 crimper is to securely attach fittings to hydraulic hoses by applying a precise crimping force. This process is crucial for creating reliable and leak-free hydraulic hose assemblies. The device utilizes a micrometer-style adjustment system, which allows for highly accurate and repeatable crimps, making it suitable for both single-use applications and repetitive production environments. The crimper's open design, featuring two-piece rubber caged die sets and a removable pusher, facilitates easy positioning of fittings before crimping. An automatic stop switch ensures that the pump shuts off once the crimp cycle is complete, enhancing safety and preventing over-crimping.

Usage Features:
The K300 crimper is designed with unique user-friendly features to ensure ease of operation and precision:
- Micrometer Style Adjustment: This feature allows for easy and accurate setting of crimp diameters. It is ideal for repetitive crimps as it provides a fully adjustable micrometer for precise results. The micrometer is simple to calibrate and requires minimum maintenance, enabling the crimping of a wide variety of hoses and fittings. To determine the finished crimp diameter, the micrometer setting is added to the closed diameter of the die set (e.g., 23mm die set + 3.0 micrometer setting = 26.0mm finished crimp diameter).
- Removable Pusher: This component, along with the open design and two-piece rubber caged die sets, allows operators to accurately position the fitting prior to crimping.
- Adjustable Retraction Stop: A built-in feature that limits ram retraction, speeding up repetitive crimps.
- Automatic Stop Switch: This switch automatically shuts off the pump when the crimp cycle is complete, ensuring consistent crimps and preventing damage.
- Easy Calibration Adjustment: The crimper allows for easy adjustment to increase or decrease the crimp OD, ensuring adherence to manufacturer specifications. Calibration involves holding the micrometer barrel with a 5/16 inch open end wrench and rotating the stem with a 5/32 inch hex key wrench; a 1/4 turn changes the crimp diameter by approximately 0.008".
- Die Orientation Decal: Guides the operator to ensure the die split faces forward for proper setup.
- Small Footprint: Designed for minimum space requirements, making it suitable for various workshop setups.
- Optional Flexible 24" Work Lamp: Enhances visibility during operation.
- Pneumatic Switch: Provides convenient control over the crimping process.
- Standard and Notched Pressure Plates: The standard pressure plate is used for most crimping applications, while the notched pressure plate is specifically designed for 90-degree fittings. When using the notched pressure plate, it is crucial to ensure it covers all 8 die fingers to prevent damage.
Maintenance Features:
Regular lubrication is key to the K300's longevity and performance:
- Grease Point #1 (Cone Base): A thin layer of CrimpX oil (supplied with the crimper) or molybdenum disulfide high-pressure grease should be applied to the surface of the cone base.
- Grease Point #2 (Die Contact Surfaces): Before sliding the pressure plate over the dies, a thin layer of CrimpX oil or molybdenum disulfide high-pressure grease should be applied to the entire area where the dies come into contact.
- Individual Die Finger Lubrication: If dies are sticking, each die finger should be lubricated individually at both positions that come into contact with the pressure plate and the bottom flange.
- Lubrication Frequency: Lubrication is not required before each crimp; typical lubrication is recommended after every 100 crimp cycles.
- Oil Level Check: The oil level in the K300 pump should be checked regularly, maintaining 1-1/2" to 2" below the vent plug when the cylinder is retracted. ISO 46 weight hydraulic oil should be used for replenishment.
- Vent Plug: Ensure the shipping plug in the pump reservoir is replaced with the air vent plug shipped with the crimper before operation.
The K300 series hydraulic hose crimper is a reliable and efficient tool, designed for precision and durability in demanding hydraulic hose assembly tasks.
