HAKKO EIGHTRON Chemical Resistance Data

Please refer to chemical resistance data in order to use our products safely. Also, please read it well concerning the following matters that demand special attention.

Please note that the chemical resistance data below is just for your reference. Before using, please always test the hose by pouring the fluid.

As Hakko hose/tubing is a multi-layer structure, the solvents/chemicals should be transferred internally, not to contact the outer layer in case the outer layer deteriorates.

Ο：Can be used without any influence or almost no influence on the material.

Δ：Can be used though having an influence on the material to some extent. Additional check before in use is required.

Χ：Cannot be used.
