* Steel performance specifications are as a result of using a steel plug with a brass coupler.
** Brass performance specifications are as a result of using a brass plus with a brass coupler.
*** 303SS working pressure is as a result of using a 303SS plug with a 303SS coupler.
Please Note: Operating pressures for this series couplings utilizing hose barb end connections
may be dramatically reduced to that of the hose rating and/or hose and end connection combination.
Consult hose manufacuturer's catalog for hose end connection ratings. If in doubt, test under controlled
conditions for suitability to application. HoseandFittings.Com, Inc. cannot assume liability for
misapplication of products resulting in equipment down-time, lost production, property damage and/or
personal injury including death.

Quick couplers are used in hydraulic or pneumatic systems to quickly connect lines without losing fluid or fluid pressure.
Quick couplers can be used under a range of pressure and temperature conditions. Quick-action couplers are ideal for use in
applications where fluid loss during connection or disconnection is unwanted. Applications include systems where tools or
other devices are routinely connected and disconnected to a central pressure supply. Common working fluids include air or
pneumatic, hydraulic fluids, steam, water, oil, fuel, chemical, gas, or solid transfer.
Important factors to think about when searching for quick couplers include body size or diameter, maximum working pressure,
and working temperature. Although different series within an interchange will mate with each other and some products are
made specifically to couple with several interchanges, in general, they do not readily couple with each other.
