Note: Protective dust plugs and caps play a crucial role in the
life of a quick coupling and no purchase of a hydraulic quick
coupling is complete without the selection of an appropriate
dust plug and cap. See pages noted in Table of Contents for
dust plugs and caps for the Parker full line of hydraulic
couplings.
Applications
Parker FS Series couplings virtually eliminate fluid loss
upon disconnection, and minimize air inclusion during
connections. They are ideal for use where spillage may
cause undesirable conditions or constitute a safety hazard.
The FS Series couplings have double shut-off flush mating
valves that are suitable for sealing off media in chemical pro-
cessing, chemical dispensing, food processing, and other
corrosive applications. Working pressures to 2000 PSI.
Features
• Simple to operate: Push to connect, pull on knurled sleeve
to disconnect.
• Flush face valves exhibit minimal spillage upon disconnect
and minimal air inclusion upon connect.
• Superior locking ball design – a large number of locking
balls distribute the workload better and allow for some
rotation between the male and female halves of the
coupling under pressure.
• Excellent flow vs pressure drop characteristics when
compared with other low spill quick couplings.
• Material construction is 316 stainless steel with
fluorocarbon seals as standard.
• Wide range of seal materials available.
• Repair kits available to replace critical elastomer seals
(all sizes).
