The Darda Quick Coupling Couple End Device for S1 10 m Hose is a complete hydraulic quick-connect coupling assembly (male and female halves) designed for installation at the end of the S1 10 m hydraulic hose used in Darda splitter and crusher systems.This coupling forms the interface between the hose and the hydraulic tool (splitter/crusher) enabling fast, secure, and leak-free hydraulic connections for both high-pressure and low-pressure circuits.It allows operators to connect or disconnect tools easily from the power pack system without losing hydraulic fluid or introducing contamination.

Design: Quick-connect hydraulic coupling set (male + female halves).

• It is Mounted at the end of the S1 10 m hose; connects hose to Darda end tool device.
• Fully compatible with Darda S1 twin-line hydraulic hose systems
• Pressure ratings: High Pressure Line: up to 700 bar (10,000 psi); Low Pressure Line: up to 60 bar (870 psi)
• Push-to-connect or sleeve-locking system; can be coupled manually without tools
• Self-sealing poppet valves automatically close when disconnected to prevent oil loss
• Secondary sleeve lock prevents accidental disconnection under pressure or vibration
• High-pressure O-ring + PTFE back-up ring to ensure leak-free operation
• Full-bore internal path to minimize pressure drop and heating

Applications: The Quick Coupling Couple End Device is installed at the tool end of the S1 10 m twin-line hydraulic hose in Darda systems. It connects to the hydraulic splitter, crusher, or combi-tool. High-Pressure Coupling: Transmits pressurized oil from the power pack through the hose into the tools hydraulic cylinder. Low-Pressure Coupling: Returns oil from the tool back to the power pack reservoir.

• Typical Uses:
  • Concrete and rock splitting (Darda Splitter Models C9, C12, C20, C4)
  • Controlled demolition and structural dismantling
  • Quarrying and trench excavation
  • Civil engineering and mining maintenance
  • Compact demolition applications (indoors, tunnels, underwater when rated)

Materials:

• Coupling Bodies: Hardened alloy steel (zinc-nickel or chrome plated) – High strength and corrosion resistance under 700 bar pressure
• Internal Valves & Springs: Stainless steel – Corrosion-resistant, precision sealing and spring return
• Locking Sleeve: Case-hardened steel – Provides secure mechanical engagement and wear resistance
• Seals/O-Rings: Nitrile (NBR) or Viton (FKM) – Resistant to hydraulic oil and temperature extremes
• Back up Rings: PTFE (Teflon) – Prevent seal extrusion at high pressures
• Dust Caps (optional): Polyamide (PA6) or Rubber – Protects coupling faces from contamination when uncoupled
