Compatibility

Note 1) The material and fluid compatibility check list provides reference values as a guide only.

Note 2) It is possible that some fluids are permeable depending on the type of fluid, its density and temperature. Any permeated

fluid may affect the products life.

Thus, when using these fluid types, verify the fluid in advance by testing it,

prior to making a decision to use it.

· Compatibility is indicated for fluid temperatures at 90°C or less.

· The product does not have an explosion proof construction. Be sure to take measures to prevent

the area around the product from becoming filled with an explosive gas, when using an explosive

fluid.
