The Darda Quick Coupling Couple for S1 10 m Hose is a complete quick-connect hydraulic coupling set (male + female halves) designed specifically for the S1-series 10 meter hydraulic hose assembly used in Darda splitting and crushing systems.This coupling allows the S1 10 m hose to connect securely to a Darda power pack on one end and to the hydraulic splitter or crusher on the other. It enables fast, leak-free, and contamination-free connection and disconnection in both the high-pressure and low-pressure hydraulic circuits.
Design: Complete hydraulic quick-coupling assembly (male + female halves)
- System Compatibility – Designed for S1 10 m Darda hose (standard twin-line hose assembly)
- Pressure Rating – Up to 700 bar (10,000 psi) for the high-pressure line; up to 60 bar (870 psi) for the low-pressure line
- Valve Type – Self-sealing poppet valves prevent fluid loss and air ingress during disconnection
- Connection Method – Push-pull or sleeve-locking type allows tool-free connection and secure locking under vibration
- Seal Type – O-ring + back-up ring configuration for leak-free sealing under extreme pressure
- Thread Type – Metric or BSPP threads (depending on tool generation)
- Coupling Function – Joins the S1 10 m hose to the tool or power pack; may include both high- and low-pressure connections as a matched pair
Applications:The Darda Quick Coupling Couple forms the connection interface between the Darda power pack (hydraulic source), and the S1 10 m twin-line hydraulic hose, which leads to the Darda splitter, crusher, or combi tool.
- Used for tool and hose interchangeability in the field allows quick switch between different Darda tools without oil loss.
- Supports the high-pressure supply and low-pressure return flow paths of the hydraulic circuit.
- Provides a reliable, sealed connection even under repeated high-pressure cycles
Common Applications: Concrete and rock splitting (C9, C12, C20, C4 models);Controlled demolition and structure dismantling;Quarrying and mining operations;Civil engineering maintenance;Underwater or confined-space hydraulic tool operation (when properly rated)
Materials:
- Coupling Body: High-strength hardened alloy steel (zinc-nickel plated) – Withstands extreme hydraulic pressure and corrosion
- Locking Sleeve: Case-hardened steel -Resists mechanical wear and vibration
- Internal Valve & Spring Components: Stainless steel – Precision operation, corrosion resistance
- Seals/O-Rings: Nitrile (NBR) or Viton (FKM) – Oil and temperature resistance
- Backup Rings: PTFE (Teflon) – Prevents extrusion under 700 bar pressure
- Dust Caps (Optional): Polyamide (PA6) or Rubber – Keeps connection faces clean when uncoupled
