Fred A. Lennon and Cullen B. Crawford founded Crawford Fitting Company in Cleveland, Ohio, in July 1947 to manufacture the Swagelok tube fitting, which used a two-ferrule design to “swage” or form the tube and lock it into place. One year later, Lennon bought out Crawford and continued to grow the business.
A 37° flare type end fitting for flexible hose The AN thread (also A-N ) is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army Air Corps and Navy, hence AN.
Fittings are also used to split or join a number of pipes together, and for other purposes. A broad variety of standardized pipe fittings are available; they are generally broken down into either a tee, an elbow, a branch, a reducer/enlarger, or a wye. Valves control fluid flow and regulate pressure.
BSPP fitting. Two types of threads are distinguished: Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP; originally also known as [1] British Standard Pipe Fitting thread/BSPF and British Standard Pipe Mechanical thread/BSPM), which have a constant diameter; denoted by the letter G.
Lokring designs patented, [4] weld equivalent pipe and tube fittings such as couplings, flanges, elbows, adapters, and more. The unique technology of the patented [ 4 ] Lokring fittings utilize "Elastic Strain Preload" [ 5 ] (ESP), and possesses a metal to metal leak-free seal that compresses or swages the pipe/tube wall.
Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 pounds per square inch (690 bar)) is involved.
