Key Features
- OEM-Spec Hydraulic Sealing — manufactured to Husqvarna's thread and pressure specifications for a secure, leak-free BSP hydraulic connection
- BSP Thread Standard — features British Standard Pipe threading, ensuring correct engagement with mating fittings in the hydraulic line without adaptation
- 3/8 Male FF Sizing — precisely sized male flat-face coupling that mates directly with the corresponding female port in the hydraulic circuit
- Confirmed Fitment — genuine OEM replacement for K3600 and K2500 power cutters; verify against your parts diagram using part number 506109821
- System Integrity — a correctly fitted coupler maintains hydraulic pressure and flow, preventing fluid loss that can lead to power drop or component damage
A hydraulic coupler serves as the connection point between hydraulic lines in the power cutter's fluid circuit, allowing pressurized hydraulic fluid to pass between components without leakage. The male flat-face (FF) design creates a flush, low-spill connection that minimizes fluid loss when lines are connected or disconnected. A worn, cross-threaded, or incorrect coupler can cause hydraulic leaks, pressure loss, and reduced cutting performance — making an exact OEM replacement the right choice for restoring full system function.
