Handling

Storage Stability

The brake fluid is hygroscopic and must therefore be stored in tightlysealed containers. After removal of brake fluid the containers must beclosed immediately.

Hydraulan 407-1 has a shelf life of at least three years when stored inoriginal closed, airtight containers at temperatures of maximum 40 C.
