But what sets a DK-LOK JIC fitting apart from other hydraulic fittings? Let’s explore this and more as we delve deeper into the world of DK-LOK JIC flare fittings.
Understanding the SAE J514 37° Flared Standard for JIC Fittings
What is SAE J514 37° Flared Standard and Why is it Important?
The Society of Automotive Engineers (SAE) developed the Joint Industrial Council (JIC) fitting standard in the early 1930s to address issues with hydraulic system leaks. The 37° flare angle ensures a tight seal and prevents leaks in high-pressure applications. The SAE J514 standard specifies the dimensions, material, and performance requirements for JIC fittings. It is widely used in industries such as aerospace, automotive, and construction.
JIC fittings are easy to install and require no special tools, making them a popular choice for field installations. They have been designed to provide leak-free connections between fluid power components due to their ability to withstand high pressure and vibration. However, proper installation and torqueing of JIC fittings are critical to ensure a leak-free connection.
How Does SAE J514 37° Flared Standard Work?
The SAE J514 standard specifies that the male fitting end has a straight thread with an O-ring groove while the female end has a straight thread with a chamfered nose or cone-shaped sealing surface. The 37-degree flare angle on both ends creates a metal-to-metal seal when tightened together.
The seal is created by compressing the flared end of the tube against the mating surface of the fitting with enough force to cause plastic deformation of both parts. This plastic deformation causes radial expansion of both parts which results in an interference fit between them sealing off any gaps that might exist between them.
