How to OrderEaton Quick Disconnect Couplings can be ordered as separatehalves. For special packaging, contact Eaton. Standard coupling part numbers are described below.DimensionsDimensions in this catalog are for reference only. Actualdimensions may vary from those shown.Coupling IdentificationGenerally, the coupling series or complete part number will bestenciled on the coupling body.Example:How to build asocket or plugpart numberwith options:Standard Part Numberfrom Part Number TablesNVVAAVB No Valve1Valve Actuator Assembly2Bleeder Valve (Plugs Only)3SL Sleeve Lock (Sockets Only)Caution:The user should carefully observe the precautions listedin this catalog. These include selection of seals and bodymaterials for fluid compatibility and recommendations onthe selection of quick disconnect couplings. In addition,care should be taken not to exceed the maximum operating pressures listed for each coupling size and type shownin the physical characteristics table for each coupling.Because of possible variations in machining tolerances,quality control, inspection and quality assurance, Eatoncoupling halves should not be used with coupling halvessupplied by other manufacturers except where such use isapproved for a particular coupling as noted in this catalog orspecifically by Eaton.4HP26 - VAA - SL - 143Seal Material:115 PTFE4118 Neoprene143 Fluorocarbon146 Buna-N5192 EPDM6235 Kalrez 236 EPDM (350 F Steam)6Notes:1) The NV option should be specified for a socket and a plug when a non-valved coupling is desired. Non-valved Series1HK through 8HKP plugs do not contain seals. Do not specify a seal material.2) The VAA option should be specified for either a socket or a plug when a one-way coupling is desired. (Not available forseries 10HK)3) The VB option can be ordered for Series 1HK through 6HKP plugs to prevent pressure build-up in disconnectedhydraulic lines or to reduce hose whip when disconnecting pneumatic lines.4) Series HK couplings are designed for use with elastomer seals. PTFE is not an elastomer. It is rigid and not resilient.Couplings with PTFE seals may leak and/or be difficult to connect. Force to connect may be reduced by heatingconnected couplings in hot water; then, cooling before disconnecting. PTFE seals are available for Series 1-HK through8-HKP, except Series P2-HK.5) The 146 seal option may be specified for fuels and hydraulic fluids that are known to cause standard Buna-N seals toswell excessively.6) The 236 EPDM seal option should be ordered for use with steam at or above 350 F. The 192 EPDM seal option shouldbe ordered for hot water above 180 F and steam below 350 F.7) Some part numbers may be subject to minimum order quantities and/or available only by special quotation.

Safety Information for EatonQuick Disconnect Couplings1.0 General Instructions.1.1 Scope. The scope of this safety bulletin is to warnagainst improper selection, use, installation, etc. of Eatoncoupling products.1.2 Distribution. A copy of this safety bulletin should bedistributed to all individuals responsible for using and/orselecting Eaton coupling products.1.3 Fail-Safe. Design all systems and equipment for fail-safeoperation such that failure of any component does notresult in personal injury and/or property damage.1.4 User Responsibility. It is the sole responsibility of theuser to select and determine that the Eaton product iscompatible with the end use application. The user isresponsible for reading and following this safety bulletinas well as any instructions or literature on the Eatonproduct being used. The user must provide necessaryproduct warnings for Eaton couplings products, usedwith systems or equipment, to the operators of thesystems or equipment.1.5 Usage with other Manufacturers’ Products. Whenusing Eaton coupling products with other manufacturers’adapters, hoses, etc., do not exceed the lowest pressurerating of any of the components being used or rupturemay result.2.0 Selection of Eaton Couplings.2.1 Pressure. Ensure that the maximum operating pressureof the system or equipment does not exceed the ratedoperating pressure of the Eaton coupling product orrupture may result.2.2 Fluid Compatibility. Verify that all components (seals,metals, etc.) are compatible with the fluid beingconveyed. Failure to do so may result in high speed fluiddischarge and/or leakage of fluids which may beflammable, toxic, at extreme temperatures, or otherwiseharmful.2.3 Temperature. Ensure that the maximum operatingtemperature of the system or equipment does notexceed the rated operating temperature of the Eatoncoupling product (including seals) or rupture may result.2.4 Coupling Size. Use properly sized couplings such thatthere is not a large pressure drop across them thusavoiding system damage due to excessive heatgeneration or failure of internal components.2.5 Sleeve Lock. Use sleeve locks or threaded couplingswhere there is the possibility of accidental disconnection.Failure to utilize sleeve locks or threaded couplings inthese applications may result in hose whip, expelledcomponents, high speed fluid discharge, systemdamage, or leakage of fluids which may be flammable,toxic, at extreme temperatures, or otherwise harmful.62.6 Connect or Disconnect Under Pressure.If connection and/or disconnection of couplings underpressure is a requirement, only use couplings designedfor connection/disconnection under pressure. Failure toutilize this type of coupling in that application may resultin hose whip, expelled components, high speed fluiddischarge, and/or system damage. Be certain not toconfuse the rated operating pressure with the ratedconnect/disconnect under pressure.2.7 Environment. Ensure that Eaton couplings arecompatible with the surrounding environment. Thesurrounding environment may be heat, salt water,moisture, chemicals, and the like. Failure to protectagainst an adverse environment may cause systemdamage, premature failure, and/or leakage of fluids whichmay be flammable, toxic, at extreme temperatures, orotherwise harmful.2.8 External Loads. Avoid any external loads such as sideloads, tensile loads, vibration, etc. Failure to do so mayresult in accidental disconnection, premature failure,system damage, and/or leakage of fluids which may beflammable, toxic, at extreme temperatures, or otherwiseharmful.2.9 Welding & Brazing. Extreme heating of plated productsabove 450 F ( 232 C) such as welding, brazing, baking,etc., where the plating is burned off, may result in therelease of deadly gases.3.0 Installation of Eaton Couplings.3.1Inspection of Product. Prior to installation, ensure thatthe Eaton product meets all of the requirements of thesystem and/or equipment it is to be used on. Ensure youhave the correct part number, function test the couplingby connecting it with a mating half. The function testshould result in smooth, non-binding operation orpremature failure may result.3.2 Cleanliness. Use end caps and plugs to reduce therisk of system contamination or damage to critical sealingsurfaces. Failure to do so may result in leakage of fluidswhich may be flammable, toxic, at extremetemperatures, or otherwise harmful. Caps and plugs arenot a secondary seal unless explicitly noted.3.3 Location. Place Eaton couplings in a safe location suchas not to expose the user to personal injury (slippage,tripping, falling, etc.) during installation, connection,disconnection and maintenance.4.0 Product Maintenance. A maintenance schedule shouldbe put in place to ensure that Eaton couplings arefunctioning properly. Eaton is not responsible for productfailures resulting from modification or impropermaintenance.4.1 Inspection. Visually inspect to ensure that there is noleakage, cracked components, corrosion build-up,contamination build-up, wear, etc. If any abnormality isencountered, the coupling should be replacedimmediately.eaton Quick Disconnect Couplings E-MEQD-MC005-E1 February 2012

Fluid CompatibilityThis chart indicates the suitability of various elastomersand metals for use with fluids to be conveyed. It is intendedfor use with Eaton couplings and should not be used todetermine compatibility for other products. It is intended asa guide only and is not a guarantee. Final selection of theproper seal or material of metal components is furtherdependent on many factors including pressure, fluid andambient temperature, concentration, duration of exposure,etc.How to Use the Chart1. Both the elastomer and the metal must be consideredwhen determining suitability of combination for acoupling.2. Locate the fluid to be conveyed and determine thesuitability of the elastomeric and metal componentsaccording to the resistance rating shown for each.3. Dimensional and operation specifications for eachcoupling can be found on the catalog pages.4. Information on seal options for couplings, and how tospecify them, are shown in the respective sections ofthis catalog.5. Be sure to check the table below for maximum operatingtemperature range of the elastomer desired.6.
