JIC Hydraulic fittings have been the solution to leak free Hydraulic Plumbing - the JIC fitting being able to withstand immense pressure as well as substantial vibration. The JIC fitting works purely by metal on metal contact, using three parts - the fitting, the sleeve and the flare nut, which in JIC Hydraulic fittings is always angled at 37degrees. JIC hydraulic fittings have always been the market leader since their introduction over thirty years ago, due to their simplicity of metal on metal contact, as well as such easy assembly and dismantling, the JIC fitting being designed for constant and repeated usage, being facilitated by the absence of small, fiddly parts.

JIC Hydraulic fittings revolutionized the hydraulics industry on their introduction thirty years ago, reducing contamination and leakage of potentially dangerous substances such as oil and petroleum. The JIC fitting is available in a wide range of types including tee, elbow and cross, as well as nuts, and reducing adapters being available, allowing attachment to varying diameter hosing. The key to the reliability of JIC Hydraulic fittings is the correct fitting to the hose end, as over tightening of the fittings, followed by repeated dismantling and assembling could result in leakage due to wearing of the thread.

The 37 degree JIC flare fittings remains the most commonly used fitting in hydraulics for many reasons; Fabrication is extremely easy, as no small or fiddly parts are, used, just metal on metal contact, as well as such a large range of sizes being available and types such as elbow and tee junction. However, leakage is sometimes possible when using JIC hydraulic fittings due to incorrect tube end connections, as well as every increasing pressure being uses, testing the JIC fitting to the utmost extremes in pressure as well as vibration. IF the seal on JIC Hydraulic fittings begin to leak, it will be noticeable by what would first be described as slight weeping, finally resulting in the system becoming sludge covered.

Other companies are now starting to manufacture, and gain recognition of hydraulic fittings, although their popularity is not of rapid growth as JIC are universal World wide, and therefore there are many compatibility issues with new brands of fitting. Leaking joints on JIC Hydraulic fittings can be eliminated by installing a conical washer between the JIC nose and flare. This is a good solution when we refer to machinery that is stationary, but would not be suitable in circumstances where the JIC fitting is being constantly dismantled and reassembled, for example in the delivery of petroleum to gasoline stations. The installing of a conical washer on the JIC Hydraulic fittings, and then a sealant being applied ensures no leakage from the pipe connection.

Leakage of JIC hydraulic fittings also occurs when insufficient torque is used when installing., and can be just as damaging as over tightening, resulting in leakage of the JIC fitting as well as possible distortion of the piping if being used with great pressure levels. Constant vibration of machinery can also cause stress, and then fatigue to the JLC Hydraulic fitting, eventually causing faults and leakage. This type of damage to the JIC hydraulic fittings can be kept to a minimum by the use of flexible hosing, or mountain the machinery in question on a platform or mounting blocks which in turn receive some of the impact of the vibration.
