CORROSION RESISTANCE
The following tables may be used only as a guide in the selection of the most suitable hose and fitting material when conveying a given medium. The listed media are in general considered to be pure, at room temperature and, unless otherwise specified, dry. A change in any of these conditions may change the rating. No
attempt has been made to account for variations in service conditions since these variables are too innumerable and complex. Additional information on service life and cautions is keyed to the following notes. “Dry” can also be referred to as “anhydrous”. Additional questions should be directed to Precision Hose & Expansion Joints.
RATING CODE:
A = Suitable (normal condition)
B = Limited Service
C = Unsuitable
Notes:
1. Susceptible to intergranular corrosion
2. May Cause Explosive reaction
3. Susceptible to stress corrosion cracking
4. Susceptible to pitting type corrosion
5. Discolors
6. Concentration over 50% and/or temperature over 200°F, refer to our Engineering Dept.
