Frequently asked questions

Common questions about KURT from 3G Electric.

What is the difference between KURT crimp hydraulic hose fittings and barbed hose fittings?

KURT crimp hydraulic hose fittings are designed to be permanently attached to a hose using a crimping machine, which compresses a ferrule onto the hose. This creates a high-pressure, leak-resistant connection. Barbed hose fittings, such as the KURT MT-08-08, have a barbed insert that is pushed into the hose and secured with a clamp or ferrule. Barbed fittings are typically used in lower-pressure applications. Crimp fittings are preferred for high-pressure hydraulic systems where a permanent, reliable connection is required.

What connection types are available in KURT hydraulic crimp fittings?

KURT hydraulic crimp fittings are available with several connection types, including JIC (Joint Industry Council), ORS (O-Ring Seal), ORB (O-Ring Boss), and NPT (National Pipe Taper). For example, the KURT 55RT69 is a 90° elbow with JIC female x male connection for -12 hose dash size. The 55RR68 is a straight ORS fitting for -6 hose. The 55RR63 is a 90° elbow ORB fitting for -6. The 55RT21 is a straight NPT fitting for -20. These options allow compatibility with various port types and sealing methods.

What hose dash sizes are covered by KURT hydraulic hose fittings?

KURT hydraulic hose fittings cover a range of hose dash sizes, typically from -4 to -20. For instance, the KURT GT-04-08 is for -4 hose (1/4 in I.D.), the MT-08-08 is for -8 hose (1/2 in I.D.), and the 55RT21 is for -20 hose (1-1/4 in I.D.). Dash size is a nominal indication of hose inside diameter, with -4 corresponding to 1/4 in, -6 to 3/8 in, -8 to 1/2 in, -12 to 3/4 in, -16 to 1 in, and -20 to 1-1/4 in. Always verify the actual hose I.D. and fitting compatibility before assembly.

What is the thread size for KURT 55RT58 JIC fitting?

The KURT 55RT58 is a 90° elbow hydraulic crimp fitting with a JIC female x male connection, designed for -8 hose dash size. Its thread size is 7/8"-14. This thread size is standard for JIC fittings in the -8 size. The fitting is made of carbon steel and is used to connect a hose to a JIC threaded port, allowing for a 90° routing of the hose. Ensure that the mating port has a compatible 7/8"-14 JIC male thread and that the hose is properly crimped.

Are KURT hydraulic hose fittings suitable for high-pressure applications?

KURT hydraulic hose fittings are designed for use in hydraulic systems, which can operate at high pressures. Crimp fittings, when properly installed with a compatible hose and crimping machine, create a permanent assembly that can withstand high-pressure fluid power applications. However, the actual pressure rating depends on the specific fitting, hose, and assembly method. It is essential to consult the manufacturer's specifications for pressure ratings and to follow proper crimping procedures. Barbed fittings are generally used in lower-pressure applications and should not be used in high-pressure systems unless specifically rated.

What is the difference between ORS and ORB connections in KURT fittings?

ORS (O-Ring Seal) and ORB (O-Ring Boss) are both O-ring sealed connection types, but they differ in design. ORS typically refers to a flat-faced O-ring seal, often used in metric or ISO 6149 ports, while ORB (O-Ring Boss) is a straight thread with an O-ring at the base, commonly used in SAE J1926 ports. KURT offers both types: the 55RR68 is an ORS fitting for -6 hose with 13/16"-16 thread, and the 55RR63 is an ORB fitting for -6 hose with 7/16"-20 thread. The choice depends on the port configuration.
