Use the "Tubing Selection Guide" below to help you select the appropriate tubing for your application. The Chemical Compatibility guide and the chemical resistance summary in the table below are only guidelines. Chemical resistance and tubing wear may vary according to usealways test the tubing you select under the actual conditions.

Chemical Resistance Classifications

ANo damage after 30 days of constant exposure.
BLittle or no damage after 30 days of constant exposure.
CSome effect after 7 days of constant exposure. Effects may include: cracking, crazing, loss of strength, discoloration, softening, or swelling. Softening and swelling are reversible in some cases.
DNot recommended for continuous use. Immediate damage may occur.
