The following Chemical Compatibility Chart is for guidance only.
In all cases, testing is advised to determine the application suitability.
Material for Couplings and Adaptors must also be compatible – refer to RYCO Hydraulics Technical Department.
Specified resistance applies only at room temperature unless otherwise stated, and within the listed concentration.
