Air King Fittings
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 ¼" to 1" range. This enables any two fittings (within that range) to be directly connected regardless of hose shank or threaded size.
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
