FD-LOK 37° flared tube fittings are the most widely used fittings

FD-LOK 37° flared tube fittings are the most widely used fittings in the world.
JIC flared fittings, as defined by the SAE J514, standards are a type of fitting machined with a 37° flare seating surface. 37° flared JIC tube fittings are the most widely used fittings in the world. JIC fitting’s appeal is its adaptability, compact design, ease of assembly, reliability and availability.
Although most JIC fittings are commonly viewed as 3,000 PSI connectors, Parher JIC flared fittings are rated at 9,000 PSI for 1/4" size to 2000 PSI for 2” size. Parher JIC 37° flare fittings are manufactured in steel, 316 stainless steel or brass, and are readily available through Hose & Fittings, Etc.
The SAE 37° flared tube fitting system consists of three components to make a tubing assembly: body, nut, and sleeve.
The SAE flared Tube fittings relies on metal-to-metal contact between the finished surface of the fitting nose and the inside diameter of the flared tubing to make a seal. SSP takes great care in the manufacturing process to produce a flared nose surface that far exceeds published specifications. This high finish reduces the likelihood of leakage due to irregularities in the flared tubing.
As the fitting nose and flared tubing are drawn together, they are supported by the fitting sleeve, which distributes the compressing load caused by the nut as it is threaded onto the fitting body during assembly.
SAE flared tube fittings are available for inch and metric tubing. Metric assemblies are constructed with standard inch bodies, and special nuts and sleeves designed for metric tubing.
