  • Meets dimensional requirements of ISO 7241-1 Series A
  • A general purpose, fluid transfer quick coupling that provides higher burst pressure and superior flow to that of Aeroquip FD56 (5600) series, Dixon K-Series, and Parker 6600 series, while providing half-for-half interchangeability.
  • Due to SafeWay’s unique poppet style valving, the S56 Series has a shorter overall length and less weight than other brands they replace.
  • Available in body sizes from 1/4″ to 1″ with pipe thread and SAE O-ring Boss (ORB) standard.
  • Ideal for minimal space applications.
  • All S56 Series quick couplings are 100% leak tested.
  • The S56 Series uses solid steel barstock in its valving and retainers; no powdered metal parts. A higher number of detent (locking) balls and a specially hardened male tip (nipple) add to the overall integrity of the product and its higher rated working pressure.
  • Unique poppet/seat design allows no extrusion gap, minimizing seal degradation under extreme pressures. Stainless steel valve springs and retainer rings are standard.
  • Method of obtaining and presenting performance data conforms to ANSI (NFPA) T3.20.2.R2, Hydraulic fluid power – Quick action couplings – Test methods.
