FS Series
Hydraulic Quick Couplings Stainless Steel
Non-Spill Flush face valves, chemical compatibility

FS Series dry disconnect couplings are ideal for closed
system transfer and dispensing of chemicals and other
fluids. The flush valves eliminate spillage and air inclusion
when connecting and disconnecting to result in minimal
environmental contamination.
Features:
• Flush, non-spill valves enable ease of cleaning
• 316 stainless steel material for chemical compatibility
• Push to connect operation
• Fluorocarbon standard seal material with options available
Applications include: B Hydraulics
• Chemical dispensing systems
• Chemical processing
• Food processing
• Corrosive media transfer
