It is intended as a guide tochemical compatibility and has been compiled from the bestavailable sources. Many factors (concentration, temperature,intermittent or continuous exposure, etc.) have a bearingupon the suitability of any material and, therefore, noguarantee, expressed or implied, is made to compatibility inany specific set of circumstances.HH95Pneumatic DivisionRichland, Michiganwww.wattsfluidair.com
