Caution:
The user should carefully observe the precautions listed
in this catalog. These include selection of seals and body
materials for fluid compatibility and recommendations on
the 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 shown
in the physical characteristics table for each coupling.
Because of possible variations in machining tolerances,
quality control, inspection and quality assurance, Eaton
coupling halves should not be used with coupling halves
supplied by other manufacturers except where such use is
approved for a particular coupling as noted in this catalog or
specifically by Eaton.
4HP26 - VAA - SL - 143
Seal Material:
115 = PTFE4
118 = Neoprene
143 = Fluorocarbon
146 = Buna-N5
192 = EPDM6
235 = Kalrez®
236 = EPDM (350°F+ Steam)6
Notes:
1) The NV option should be specified for a socket and a plug when a non-valved coupling is desired. Non-valved Series
1HK 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 for
series 10HK)
3) The VB option can be ordered for Series 1HK through 6HKP plugs to prevent pressure build-up in disconnected
hydraulic 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 heating
connected couplings in hot water; then, cooling before disconnecting. PTFE seals are available for Series 1-HK through
8-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 to
swell excessively.
6) The 236 EPDM seal option should be ordered for use with steam at or above 350° F. The 192 EPDM seal option should
be 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. Consult
your local distributor or sales representative.

Safety Information for Eaton
Quick Disconnect Couplings
1.0 General Instructions.
1.1 Scope. The scope of this safety bulletin is to warn
against improper selection, use, installation, etc. of Eaton
coupling products.
1.2 Distribution. A copy of this safety bulletin should be
distributed to all individuals responsible for using and/or
selecting Eaton coupling products.
1.3 Fail-Safe. Design all systems and equipment for fail-safe
operation such that failure of any component does not
result in personal injury and/or property damage.
1.4 User Responsibility. It is the sole responsibility of the
user to select and determine that the Eaton product is
compatible with the end use application. The user is
responsible for reading and following this safety bulletin
as well as any instructions or literature on the Eaton
product being used. The user must provide necessary
product warnings for Eaton couplings products, used
with systems or equipment, to the operators of the
systems or equipment.
1.5 Usage with other Manufacturers’ Products. When using Eaton coupling products with other manufacturers’
adapters, hoses, etc., do not exceed the lowest pressure
rating of any of the components being used or rupture
may result.
2.0 Selection of Eaton Couplings.
2.1 Pressure. Ensure that the maximum operating pressure
of the system or equipment does not exceed the rated
operating pressure of the Eaton coupling product or
rupture may result.
2.2 Fluid Compatibility. Verify that all components (seals,
metals, etc.) are compatible with the fluid being
conveyed. Failure to do so may result in high speed fluid
discharge and/or leakage of fluids which may be
flammable, toxic, at extreme temperatures, or otherwise
harmful.
2.3 Temperature. Ensure that the maximum operating
temperature of the system or equipment does not
exceed the rated operating temperature of the Eaton
coupling product (including seals) or rupture may result.
2.4 Coupling Size. Use properly sized couplings such that
there is not a large pressure drop across them thus
avoiding system damage due to excessive heat
generation or failure of internal components.
2.5 Sleeve Lock. Use sleeve locks or threaded couplings
where there is the possibility of accidental disconnection.
Failure to utilize sleeve locks or threaded couplings in
these applications may result in hose whip, expelled
components, high speed fluid discharge, system
damage, or leakage of fluids which may be flammable,
toxic, at extreme temperatures, or otherwise harmful.
6
2.6 Connect or Disconnect Under Pressure.
If connection and/or disconnection of couplings under
pressure is a requirement, only use couplings designed
for connection/disconnection under pressure. Failure to
utilize this type of coupling in that application may result
in hose whip, expelled components, high speed fluid
discharge, and/or system damage. Be certain not to
confuse the rated operating pressure with the rated
connect/disconnect under pressure.
2.7 Environment. Ensure that Eaton couplings are
compatible with the surrounding environment. The
surrounding environment may be heat, salt water,
moisture, chemicals, and the like. Failure to protect
against an adverse environment may cause system
damage, premature failure, and/or leakage of fluids which
may be flammable, toxic, at extreme temperatures, or
otherwise harmful.
2.8 External Loads. Avoid any external loads such as side
loads, tensile loads, vibration, etc. Failure to do so may
result in accidental disconnection, premature failure,
system damage, and/or leakage of fluids which may be
flammable, toxic, at extreme temperatures, or otherwise
harmful.
2.9 Welding & Brazing. Extreme heating of plated products
above +450°F (+232°C) such as welding, brazing, baking,
etc., where the plating is burned off, may result in the
release of deadly gases.
3.0 Installation of Eaton Couplings.
3.1 Inspection of Product. Prior to installation, ensure that
the Eaton product meets all of the requirements of the
system and/or equipment it is to be used on. Ensure you
have the correct part number, function test the coupling
by connecting it with a mating half. The function test
should result in smooth, non-binding operation or
premature failure may result.
3.2Cleanliness. Use end caps and plugs to reduce the risk of system contamination or damage to critical sealing
surfaces. Failure to do so may result in leakage of fluids
which may be flammable, toxic, at extreme
temperatures, or otherwise harmful. Caps and plugs are
not a secondary seal unless explicitly noted.
3.3 Location. Place Eaton couplings in a safe location such
as not to expose the user to personal injury (slippage,
tripping, falling, etc.) during installation, connection,
disconnection and maintenance.
4.0Product Maintenance. A maintenance schedule should
be put in place to ensure that Eaton couplings are
functioning properly. Eaton is not responsible for product
failures resulting from modification or improper
maintenance.
4.1 Inspection. Visually inspect to ensure that there is no
leakage, cracked components, corrosion build-up,
contamination build-up, wear, etc. If any abnormality is
encountered, the coupling should be replaced
immediately.

Bleeder-Style Plugs & One-Way Shut-Off Conversion Via (VAA)
Bleeder-style plugs can be used on air lines to prevent hose
whip when disconnecting a line by reducing the exhaust
velocity of air. Bleeder-style plugs can be used on hydraulic
lines to prevent static pressure from building up in disconnected
lines. Valves of these plugs are manufactured such that a small
leak path exists when the plug is disconnected.
Bleeder-style plugs are available in Series 1HK through 6HKP.
