KURT

KURT is a manufacturer of hydraulic hose fittings and adapters, recognized for producing components that meet SAE J514 and ISO 12151-2 specifications for JIC (Joint Industry Council) 37° flare connections. The product line available through 3G Electric focuses on crimp-style fittings constructed from carbon steel, designed for permanent attachment to hydraulic hoses using a crimping machine. These fittings are available in straight, 90° elbow, and 90° long elbow configurations, with male x male or female x male gender combinations. Thread sizes range from 7/16"-20 (for -4 hose dash size) up to 1-5/8"-12 (for -20 hose dash size), covering common industrial hydraulic applications. The fittings are intended for use with standard hydraulic hoses and are compatible with JIC male or female ports on pumps, valves, cylinders, and other hydraulic components. 3G Electric stocks a selection of KURT crimp fittings to support maintenance, repair, and assembly operations for hydraulic systems in sectors such as construction equipment, material handling, agricultural machinery, and industrial manufacturing. The fittings are supplied without a hose, requiring the end user to crimp them onto the appropriate hose using a crimper calibrated to the manufacturer's specifications. 3G Electric provides global logistics support, enabling procurement teams worldwide to source these components with consistent part numbering and specification data.

Frequently asked questions

Common questions about KURT from 3G Electric.

What SAE or ISO standards do KURT JIC crimp fittings comply with?

KURT JIC crimp fittings are designed to meet SAE J514 and ISO 12151-2 specifications for 37° flare connections. These standards define thread dimensions, flare angles, and sealing surface requirements to ensure interchangeability with standard JIC ports and mating fittings. The carbon steel construction and thread tolerances are intended to provide reliable sealing under hydraulic pressure within the rated working pressure of the hose assembly.

What hose dash sizes are available for KURT crimp fittings from 3G Electric?

3G Electric stocks KURT crimp fittings for hose dash sizes -4, -8, -10, -12, and -20. These correspond to nominal hose inside diameters of 1/4 inch, 1/2 inch, 5/8 inch, 3/4 inch, and 1-1/4 inch respectively. Each fitting is marked with the dash size and thread size to facilitate correct selection. The range covers common hydraulic hose sizes used in medium- to high-pressure systems.

Can KURT crimp fittings be reused after removal from a hose?

KURT crimp fittings are designed for one-time use. The crimping process deforms the fitting ferrule permanently onto the hose, creating a mechanical bond. Once crimped, the fitting cannot be removed and reinstalled without compromising the seal or structural integrity. For repairs, the entire hose assembly must be replaced with a new fitting and hose section.

What is the difference between a KURT FJX and MJ series fitting?

The FJX series fittings have a female JIC swivel nut on one end and a hose crimp connection on the other, allowing connection to a male JIC port. The MJ series fittings have a male JIC thread on one end and a hose crimp connection on the other, designed to connect to a female JIC swivel nut or port. Both are straight configurations unless specified as 90° elbow (FJX90) or long elbow (FJX90L).

What material is used for KURT hydraulic crimp fittings?

KURT hydraulic crimp fittings stocked by 3G Electric are made from carbon steel. Carbon steel provides sufficient tensile strength and durability for hydraulic systems operating at pressures typical of industrial equipment. The fittings may have a protective finish to resist corrosion, though specific coating details should be verified with the manufacturer for environmental compatibility.

How do I select the correct KURT crimp fitting for my hose?

Select the fitting based on the hose dash size (e.g., -8 for 1/2-inch hose), the desired connection type (JIC male or female), and the fitting configuration (straight, 90° elbow, or long elbow). Verify the thread size matches the port on your equipment. The fitting part number indicates these parameters: for example, MJ-08-10 is a male JIC straight fitting for -8 hose with a 7/8"-14 thread. Always consult the crimp specification for the hose brand to ensure proper crimp diameter.
