Single Shut-Off Couplings

Single Shut-Off couplings are primarily used for pneumaticapplications, connecting air tools, hoses, or other implementsto compressed air supplies.They are also used with othergases, and with the exception of the E-z-mate Series can be

used with low pressure fluids.The coupler half contains ashut-off valve that is automatically opened when a matingnipple is inserted and automatically closes when the nipple isremoved.

Parker Single Shut-Off couplings come in three basicdesigns: general purpose/manual connect, generalpurpose/push-to-connect, and special purpose.

The standard seal material for all Parker Single Shut-Offcouplers is Nitrile. Ethylene Propylene, Fluorocarbon, andNeoprene seals are available as options.See thecomprehensive Fluid Compatibility Chart that providesguidelines for seal and body material selection.When thereis need for further assistance in selecting the appropriateseal material, please consult factory.

Introduction

Pneumatic Quick Couplings

General Ordering Information

When ordering Parker coupler bodies and nipples, pleasestate the part number of each type of coupler body and eachtype of nipple desired. List coupler bodies and nipples asseparate items rather than in combinations. Be sure to doublecheck thread or hose sizes of items required.

Many of Parkers coupling products are available with uniquenon-standard options well suited to very specific applications.Examples of unusual end use applications might include:high temperatures (above 250 F), extremelycaustic/corrosive solutions passing through the coupling,external/environmental corrosion situations, or other highwear and tear situations such as dragging the product along

the ground. It is always recommended that the QuickCoupling Division be contacted with any questionsconcerning specific product application needs.

Typically, a prefix or suffix is added to the base part numberto specify a non-standard O-ring seal, or special option suchas a sleeve lock. The list at right illustrates the designations.

Please Note: Certain couplings series have additionalSpecial Order Information which should be referred to inordering those products. If applicable to the product, SpecialOrder Information is found next to the Features andSpecifications charts. See the Coupling Selection andOrdering Guide for further information.
