Industry Leader in Quick Action Couplings

S51 Series

heavy-duty, Double shut-off quick coupling

  s51 series
Applications include "wet-line-kits" used widely on dump trailers, mobile drilling rigs, mining equipment, large mobile equipment, salt spreaders, and chemical transfer units.
Minimum air inclusion during connection and minimum fluid spillage during disconnection.
Interchangeable half-for-half with the Parker 6100 Series, Aeroquip FD51 (5100) Series, and Snap-Tite 78 Series.
Brass body, tip and poppet, combined with a rugged steel valve, provide corrosion resistance and durability.
Optional electroless nickel plated steel (-STL) tip and body shell is combined with standard internal parts and locking mechanism to provide a rugged, less costly alternative that is well suited for most applications.
All S51 Series quick couplings are 100% leak tested.
Connection-under-pressure can be accomplished due to our heavy-duty poppet assembly with bonded valve seals.
A rugged, high quality machined carbon steel valve; no powdered metal parts.
Available with either a ductile cast iron wing nut or heavy duty steel hex nut to make a threaded connection.
SafeWay's Ductile Cast Iron Wing Nut is specifically built to withstand hammer blows associated with connection and disconnection-under-pressure.
Available heavy-duty flange provides a simple and reliable method of bulkhead mounting the quick coupling.
Completely field serviceable with seal repair kits.
Method of obtaining and presenting performance data conforms to ANSI (NFPA) T3.20.2.R2, Hydraulic fluid power - Quick action couplings - Test methods.
