What Our Customers Are Saying
Choosing the right hydraulic fitting depends on several factors, including connection type and thread standard, operating pressure, hose size, environment, and hydraulic fluid type. You might wonder if you need a JIC, NPT, ORFS, BSP, metric, or SAE fitting? Using the right fitting ensures efficient system operation and reduces the risk of system failure and leaks.
To determine the correct size of a hydraulic fitting, you have to know three measurements of the hydraulic hose you will be using: the size of the hose itself, the size of port that the hose will connect into, and the size of the thread. In general, the identification of the hydraulic fitting is done with two numbers separated by a hyphen (-), where the first number will represent the nominal size of the hydraulic fitting and the second number represents the thread type. You must consult the general equipment specifications, as well as the specific dimensions of your hydraulic hose and fitting to help ensure your choice is the correct one for a proper seal and a safe functioning hydraulic system.
JIC, NPT, BSP, ORFS use a separate kind of connection, and sealing. JIC has 37° flare, NPT has tapered threads, BSP is used most worldwide, and ORFS uses an O-ring seal to make sure no fluid escapes. The right fitting is based on pressure, working temp, other system parameters and also on where you are.
Adhering to the instructions from the manufacturer will help enable proper installation of hydraulic fittings which will ensure they operate correctly and safely. The general steps involved in installations are the cleaning of surfaces, tightening of fittings at the correct torque value, and finally identifying any leaks through a leak test. An incorrectly fitted hydraulic fitting can result in the damage of the fitting itself, fluid leaks, or other issues related to your hydraulic system.
