Barrier Fluid FDA® is a pure, non-reactive, synthetic fluid that provides superior lubrication and cooling for double and tandem mechanical seals.
Barrier Fluid FDA® provides very stable seal performance over an extremely wide temperature range, satisfying most seal service requirements. Barrier Fluid FDA® is extremely clean and has excellent low temperature fluidity and heat transfer properties.

Barrier Fluid FDA® is sanctioned under the FDA CFR Title 21 Sections 178.3620 (a) (b); 172.878; 175.105: 172.200 and 210: 177.2260, 2600 and 2800; 178.3570 and 3910.
