This fitting can be assembled onto hydraulic hard tubing in the field with minimal tooling required. They are available in low-pressure black iron and brass, and high-pressure steel and stainless steel.
This connection style is used in pneumatic and process systems and hydraulic systems. As such, there is a full line of hose fittings for this style, and it can be used with metric-sized tubing.
Newer versions of this fitting style incorporate a captured elastomeric seal on the mating surface, providing better sealing and reusability. Four-Bolt Flange : The 4-bolt flange connections conforming to SAE J and ISO and -2 are proven, leak-free connections and are especially suited for larger sizes, higher pressures and assembly in tight quarters. Locate a distributor near you. The hose assembly can be made anywhere provided that the fitting and the hose on hand is Field Attachable Fitting compatible.
In most cases, a field attachable fitting consists of two pieces; a socket and a nipple. Additionally, there are available fittings that can connect JIC fittings to any foreign or American port, and jump sizes can expand or reduce between any sizes.
A key benefit of JIC is the great variety of product that is typically stocked by vendors, including straights, elbows, long drops and male or female threads. Availability : JIC and NPT fittings have been the field standard for decades, and they are readily available in both volume and variety.
As a growing number of OEMs converts to O-ring face seals and DIN metric fitting styles, any hydraulic hose shop should be able to identify these new fittings, but the selection may be limited.

Note: dash numbers are nominal. Since metric measurements give the true sizes of a tube or a fluid pipe, dash numbers do not apply for them. For example, for M12x1. The male and female threads connect and a seal is formed when the two are mated together i. This is known as a dry seal thread. If additional sealing is required, teflon and pipe dope can be applied.
The National Fluid Power Association NFPA does not recommend the connection for hydraulic applications, however it is commonly found in fluid piping systems. Both male and female NSPM connectors' threads are straight, while the male has a internal chamfer, the female has an inverted seat. A mechanical connection is made when the both male and female are mated together. The tapered seat creates a leak-resistant connection, and are commonly found in fluid power systems.
The flare seats of the male and female seal together when the straight threads are joined. The straight threads of the each half hold the connection together mechanically. These connectors are widely found in low pressure applications like refrigerant and fuel lines, as well as automotive piping applications.
The female port of the O-Ring Boss has a sealing face, chamfer, and a straight thread. The male connector has an O-ring and a straight thread. The seal is made when the O-ring is squeezed into the chamfer.
The male and female threads bind together to make a mechanically strong connection. This connection is common in high pressure hydraulic systems. The male half of this connection has a seat with a straight thread. The female has a compression sleeve with a straight thread. Along with the sleeve, a female nut and tube partly form the female connection.
With the male half, the seal forms between the 24O seat and the compression sleeve. With the female half, the seal forms between the tubing and compression sleeve. In the hydraulics industry, JIC and AN fittings are terms thrown around and searched for online interchangeably. But, are they? Air-Way digs in. Military aviation applications.
These fittings are made to meet strict performance standards related to the aeronautical industry. The use of "AN" fittings increased to include most branches of U.
The Joint Industries Council JIC , sought to clear the air by standardizing the specifications on this type of fitting by creating the "JIC" fitting standard, a degree fitting with a slightly lower class of thread quality than the military AN version. Learn how to cross reference Military Specification numbers with this Air-Way tutorial. The most notable difference between these standards are in the threads. Material requirements also differ greatly.
These two fittings function the same, they look the same, AND the industrial version is much less expensive to manufacturer.
