DEUBLIN 2117-001-013

The Deublin 2117-001-013 Rotary Union is a high-volume 1″ Monoflow unit specifically engineered for the heavy-duty requirements of forestry yarders and tower haulers. Designed to provide maximum flow for primary winch drum clutches and braking systems, it ensures rapid, reliable response times in New Zealand’s most demanding logging environments

High-Volume Response: Deublin 2117-001-013 for Yarder Main Drums

When you are pulling heavy turns on a skyline, you need an air or hydraulic supply that doesn’t bottleneck. The Deublin 2117-001-013 (2117-001-103) features a full 1″ NPT flow path, making it the preferred choice for the main drum clutches on large-scale yarders. Its ability to move high volumes of fluid instantly means your winch engagement is crisp and your braking is immediate—critical factors when working steep NZ faces.

Built for the “shock-load” reality of the logging landing, the 2117 series features a robust anodized aluminum housing and a hardened steel rotor. The micro-lapped carbon-graphite seals are designed to resist the fine wood dust and extreme vibration that typical industrial unions can’t handle. By installing a genuine Deublin 2117 series union, you are investing in a component proven to minimize downtime and maintain the high-cycle production required in the New Zealand bush.

Yarder & Heavy Hauler Applications

The Deublin 2117-001-013 is primarily utilized for main winch drum clutch and brake actuation on mobile yarders and tower haulers. It is a critical replacement part for large Madill, Thunderbird, and Skagit machines that require 1″ high-flow lines to maintain system pressure. Its heavy-duty design is perfectly suited for the intense duty cycles and variable weather conditions found throughout New Zealand’s commercial forest blocks.
