Pneumatics
Single Shut-Off Couplings
Single Shut-Off couplings are primarily used for pneumatic
applications, connecting air tools, hoses, or other implements
to compressed air supplies. They are also used with other
gases, and with the exception of the E-z-mate Series can be
used with low pressure fluids. The coupler half contains a
shut-off valve that is automatically opened when a mating
nipple is inserted and automatically closes when the nipple is
removed.
Parker Single Shut-Off couplings come in three basic
designs: general purpose/manual connect, general
purpose/push-to-connect, and special purpose.
The standard seal material for all Parker Single Shut-Off
couplers is Nitrile. Ethylene Propylene, Fluorocarbon, and
Neoprene seals are available as options. See the
comprehensive Fluid Compatibility Chart that provides
guidelines for seal and body material selection. When there
is need for further assistance in selecting the appropriate
seal material, please consult factory.
Introduction
Pneumatic Quick Couplings
General Ordering Information
When ordering Parker coupler bodies and nipples, please
state the part number of each type of coupler body and each
type of nipple desired. List coupler bodies and nipples as
separate items rather than in combinations. Be sure to double
check thread or hose sizes of items required.
Many of Parker’s coupling products are available with unique
non-standard options well suited to very specific applications.
Examples of unusual end use applications might include:
high temperatures (above 250° F), extremely
caustic/corrosive solutions passing through the coupling,
external/environmental corrosion situations, or other high
wear and tear situations such as dragging the product along
the ground. It is always recommended that the Quick
Coupling Division be contacted with any questions
concerning specific product application needs.
Typically, a prefix or suffix is added to the base part number
to specify a non-standard O-ring seal, or special option such
as a sleeve lock. The list at right illustrates the designations.
Please Note: Certain couplings series have additional
“Special Order Information” which should be referred to in
ordering those products. If applicable to the product, “Special
Order Information” is found next to the Features and
Specifications charts. See the Coupling Selection and
Ordering Guide for further information.
Checklist for Selecting Quick Couplings
What are the functional requirements of the coupling?
What is the maximum working pressure of the application?
Which seals and body material are compatible with the system’s fluid?
Is the application static or dynamic?
What size coupler is required?
What is the maximum pressure drop suitable for the application?
Does the application require the ability to connect and disconnect under pressure?
What is the media temperature and ambient temperature?
What end configurations are required?
Is an industry interchange coupler required?
Is air inclusion and fluid loss a concern in the application?
