Minimum Spill, High Flow,

Heavy-Duty Quick Coupling

SafeWay’s S51 Series is a heavy-duty, thread to connect quick coupling capable of containing a variety of fluids. This Series features minimum air inclusion during connection and minimum fluid spillage during disconnection. The S51 Series is ideally suited for use on dump trailers in the connection of the wet-line hydraulic system. This interchange is also widely used on oil field equipment and wherever connection under pressure with little or no spillage is required. This model has a 1-1/4″ body size with 1-1/4″ female pipe threads.

• Brass body, tip and poppet, combined with a rugged steel valve, provide corrosion resistancce and durability.

• SafeWay’s Ductile Cast Iron Wing Nut is specifically built to withstand hammer blows associated with connection and disconnection under pressure.

• 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.

• 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.

• Method of obtaining and presenting performance data conforms to ANSI (NFPA) T3.20.2.R2, Hydraulic fluid power – Quick action couplings – Test methods.
