Cross-reference part number 531118003 against your parts diagram to confirm fitment before ordering. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM Hydraulic Integrity — manufactured to Husqvarna's exact pressure and flow specifications for the 1800UV coupling standard, ensuring a sealed, pressure-rated connection without fluid bypass or leakage
- Drop-In Hydraulic Line Replacement — the female quick-connect interface mates directly with the corresponding male coupling on compatible Husqvarna hydraulic circuits, requiring no line modifications or adapter fittings
- Broad Cross-Equipment Fitment — compatible with PP440HF, PP440, PP480, PP480HF, PP492, and PP325E power packs; DXR95, DXR140, DXR145, DXR250, DXR270, DXR275, DXR300, DXR305, DXR310, and DXR315 demolition robots; WS460, WS462, and WS463 wall saws; the FS700E floor saw; the CS2512 wire saw; and the DM406 core drill
- Restored Hydraulic Flow — a correctly seated coupling maintains consistent hydraulic pressure to downstream tools and drives; a worn or damaged coupling can cause pressure loss, fluid leakage, and unplanned equipment shutdown
- Safe Hydraulic Disconnection — the quick-connect design allows controlled, spill-minimized disconnection of pressurized hydraulic lines, reducing the risk of fluid injection injuries and hydraulic fluid exposure during tool changes or servicing
A quick coupling is the mechanical interface that connects and disconnects pressurized hydraulic lines between a power source and a hydraulic tool or drive unit. The female half of the coupling receives the male fitting and locks it in place, maintaining a sealed passage for hydraulic fluid under high operating pressure. When the coupling wears, cracks, or fails to seat correctly, it can allow fluid to leak past the seal or interrupt flow entirely — reducing the output power delivered to the connected tool and creating a potential safety hazard on the worksite.
