Confirm the specifications. 

This product is designed only for use in compressed air systems including vacuum. Do not operate at 
pressures or temperatures outside of the specification, as this could cause damage or malfunction (Refer 
to the specifications.) 
Please contact SMC if using fluids other than compressed air (including vacuum) generated by air 
compressor. 
SMC does not guarantee against any damage if the product is used outside of the specification range.
