Important Engineering Disclaimer:
Compatibility data is a preliminary screening guide only. Verify against actual concentration, operating temperature and pressure, fluid impurities, velocity/erosion, corrosion allowance, gasket seating stress, mechanical seal arrangement, vendor recommendations, applicable code, project specification, and the current Safety Data Sheet before engineering use. Ratings reflect Graco Chemical Compatibility Guide (Updated 10/29/2024) and are not a current SDS/GHS classification.
