JIC Hydraulic Fittings: All You Need to Know
JIC stands for Joint Industry Council, a standard that defines hydraulic fittings with a 37-degree flare seating surface and parallel thread machining. These fittings are usually made of nickel alloy or brass, and carbon steel and stainless steel, creating a metal-to-metal seal. This metal-to-metal cone flare ensures a secure and reliable connection under high pressure and vibration, making it a go-to choice for connecting components in hydraulic systems.
