Warning
(1) Check the specifications.
Do not use the product outside of the specified pressure and temperature range, as this may
cause breakage or operation failure. (Refer to the specifications.)
SMC does not guarantee against any damage if the product is used outside of the specification
range.
(2) Disassembly and modification prohibited
Do not disassemble the product or make any modifications, including additional machining.
This may cause human injury and/or an accident.
(3) Check if PTFE is compatible with application.
The sealing agent applied to the threads includes PTFE (polytetrafluoroethylene) powder.
Check whether or not it could cause issues in your application.
(4) The product cannot be used as a stop valve to achieve zero leakage. A certain amount of
leakage is allowed in the product specifications.
(5) The KKA series cannot be connected to SMC's KK, KKH, KK13 or KK130 series or other
manufacturer's quick couplers.
This will cause leakage, damage, and disconnection of the
plug. Check the specifications before use.
(6) Do not connect or remove the product while it is pressurized or residual pressure remains.
The pressure can cause disconnection.
(7) Never pressurize the coupler without check valve in disconnecting condition.
The connected
pipings may break loose, causing danger.
(8) The coupler without check valve leaks fluid in the piping when it is disconnected. Be careful
especially when fluid which may cause danger, such as fluid with high temperature and
pressure, is used. In such cases, we strongly recommend using a product with a stop valve.
(9) The product will become hot if used with a high temperature fluid.
If the hot product comes into
contact with peripheral equipment or parts, it may cause fire.
Please attach and detach the plug and socket after keeping the normal temperature.

Caution
(1) For a plug and socket connection, select a plug and socket with the same body size.
If their body sizes are different, they cannot be connected. This will cause leakage, damage,
and disconnection of the plug. Inserting anything other than the special plug into the socket
may cause the product failure.
(2) Do not use in a location where the connecting threads and tubing connection will oscillate or
rotate. Oscillation or rotation will disconnect the tubing from the thread.
(3) Do not use the product with flammable, explosive, or toxic substances such as gas, gas fuel,
and refrigerants. Such substances may permeate from inside to outside of the tubing.
