DEUBLIN 17-025-012

The Deublin 17-025-012 Rotary Union is a high-speed Monoflow unit specifically engineered for the precise pilot control systems of forestry yarders and mobile haulers. Designed for reliability in compact spaces, it provides the responsive fluid transfer required for auxiliary winch controls and drum sensors on demanding NZ logging sites.

Precision Control: Deublin 17-025-012 for Yarder Pilot Systems

In the complex hydraulic systems of a forestry yarder, small components often do the most important work. The Deublin 17-025-012 (17 series) is a compact, self-supported union built to deliver pilot signals with zero lag. When you are feathering the controls of a heavy hauler on a steep NZ hillside, you need the assurance that every subtle movement is transmitted accurately to your winch clutches and brakes.

Constructed with a lightweight aluminum housing and a stainless steel rotor, the 17-025-012 is built to resist corrosion and wear in the harsh, high-vibration environment of a logging landing. Its specialized carbon-graphite seals are designed for high-speed operation, ensuring that even during rapid drum cycles, your pilot lines maintain constant pressure without overheating. By choosing a genuine Deublin 17 series union, you are investing in the fine-tuned precision required for safe and productive cable logging.

Yarder & Auxiliary Control Applications

The Deublin 17-025-012 is a primary component for pilot control lines and auxiliary sensing on forestry yarders and haulers. It is frequently utilized in the control cabs and drum assemblies of Madill, Thunderbird, and Brightwater machines where space is at a premium but high-speed reliability is non-negotiable. Its robust design ensures consistent performance across the wide temperature ranges found in New Zealand’s forest blocks.
