The Darda Set of Complete Quick Couplings (S1 Hose) is a matched pair of high-pressure and low-pressure hydraulic quick-connect couplings designed for the S1 hose assembly in Darda hydraulic splitter and crusher systems.This complete set allows for rapid, leak-free connection between the Darda power pack and hydraulic tool (splitter, crusher, or combi tool). It ensures reliable hydraulic flow in both pressure and return lines during operation.Essentially, this set combines both: one high-pressure coupling (for the supply line), and one low-pressure coupling (for the return line).

Design: Dual-line hydraulic quick coupling system (pressure and return).

Operating Pressure: High Pressure Line: up to 700 bar (10,000 psi); Low Pressure Line: up to 60 bar (870 psi)
Connection Type:Quick-release sleeve or push-pull mechanism allowing tool-free coupling. Self-sealing valves prevent oil loss and air entry.
Compatibility: Designed specifically for Darda S1 hose systems, used on all standard Darda splitters and crushers (e.g., C9, C12, C20, C4 models).
Sealing System:High-performance O-ring seals (NBR or FKM). Backup PTFE rings for extrusion resistance at high pressure.
Locking Mechanism:Steel locking balls or sleeves for secure engagement under vibration and shock loading.
Coupling Standard: Custom Darda design, compatible with Darda hydraulic tools and power packs only.

Applications: This set enables connection of the complete hydraulic circuit between the Darda power pack and its attached tool (splitter, crusher, or shear). The High-Pressure Coupling delivers pressurized hydraulic oil from the power pack to the tools cylinder. The Low-Pressure Coupling returns the oil to the reservoir after actuation.

Use Cases:Concrete and rock splitting,Controlled demolition.Mining and quarrying,Rescue and maintenance operations
System Integration: Darda Hydraulic Splitters (C9, C12, C20, C4, etc.); Darda Power Packs (HCS 6, HCS 8, HPP series); S1 Hose Assemblies standard dual-line hose set for Darda equipment.
Field Advantage:Quick coupling minimizes downtime when switching tools;Prevents oil contamination and spills;Safe under pressure and vibration.

Contents:

High Pressure Coupling (male + female) – Transfers pressurized oil (up to 700 bar) from power pack to splitter/crusher
Low Pressure Coupling (male + female) – Returns hydraulic oil to the power pack reservoir
Dust Caps (optional) – Protect coupling ends from dirt, dust, and debris when disconnected
Sealing O-rings (installed) – Ensure leak-free sealing in both coupling halves
