Air King

SERVICE - Dixon "Air King" couplings are recommended for use on air lines for virtually any type of pneumatic equipment. The maximum recommended working pressure for Dixon "Air King"universal couplings is 150 PSI or less at ambient temperature (70° F).

FEATURES - Dixon "Air King" fittings have a universal head which is identical for all parts (hose ends, male NPT and female NPT) within the 1/4" to 1" range. This enables any two fittings (within that range) to be directly connected regardless of hose shank or threaded size. Dixon "Air King" couplings with interlocking ferrule also have the standard "Air King" universal head. This enables any of the "Air King" with ferrule couplings to connect directly to any other "Air King" coupling within the 1/4" - 1" range. The ferrule comes attached to the fitting for easy installation. The ferrules can be swaged or crimped depending on your coupling installation equipment. Swaging and crimping dimensions are provided on page 9 of this brochure.

CONNECTION - Connections are made by pushing two heads together and turning one quarter turn in a clockwise direction. When this is done and the heads have seated properly, the small holes through the flange on the side of each coupling head will line up. An "Air King" Safety Clip should be inserted at this point to assure the "Air King" couplings will not become accidentally disconnected. If a Safety Clip is not available, insert a cotter pin or wire type retainer through the holes. The fitting is now ready to be put into service.

DISCONNECTION - Remove the safety clip, cotter pin or wire. Press the heads firmly together and turn them counterclockwise. The heads will then separate. NEVER attempt to disconnect any hose while pressure is in the line.

INTERCHANGE - Although "Air King" couplings may interchange with other manufacturers' fittings, we do not recommend their use with other products. Not all locking heads are made to the same standards as Dixon "Air King". Use with other brands of fittings may create an unsafe condition, due to poor design or worn equipment.

The use of an "Air King" Safety Clip, cotter pin, or wire type retainer is necessary to assure "Air King" Universal Couplings will not become accidentally disconnected. This guarantees the fittings are properly connected as a safety clip or pin will not go through the holes in the mating flanges until the couplings are locked in place. Only one "Air King" Safety Clip or wire type retainer is required for each "Air King" Universal Coupling Assembly.

Synthetic cord Lanyards (not pictured) are available separately for fastening the Safety Clip to the locking head (see page 6).

Dixon's couplings and retention devices are designed to work safely for their intended use. The selection of the proper hose, coupling, and retention devices; and the proper application of the coupling to the hose are of utmost importance. Users must consider the size, temperature, application, media, pressure, and hose and coupling manufacturer's recommendations when selecting the proper hose assembly components. Dixon recommends that all hose assemblies be tested in accordance with the Rubber Manufacturers Association's recommendations and be inspected regularly (before each use), to ensure that they are not damaged or have become loose.

Where safety devices are integral to the coupling, they must be working and utilized. The use of supplementary safety devices, such as safety clips and "King Cable" safety cables, are recommended. If any problem is detected, couplings must be removed from service immediately.

Dixon is always available for consultation concerning the couplings and accessories we sell. We will suggest the appropriate fittings, test those applications when necessary, and train distributors in assembly procedures. We strongly recommend that distributors and end users make use of these services. Dixon can be contacted at 1-800-355-1991.
