Chemical Resistance / Compatibility Chart
The following chart may be used only as a guide in the selection of the most suitable hose, expansion joint and fitting material when conveying a given medium.
The compatibility of any particular medium however should be reconfirmed with us by email prior to its usage for approval.
No attempt has been made to account for variations in service conditions since these variables are too innumerable and complex.
