ZF Oil Pipe – Precision Fluid Conduit for Off-Highway Transmissions
Engineered specifically for the demanding hydraulic circuits of ZF’s WG200 and ERGOPOWER series, this oil pipe serves as a critical pressure and return line within the transmission lubrication and clutch actuation system. Unlike generic tubing, this component is designed to maintain consistent oil flow under extreme thermal cycling and high-pressure spikes common in heavy earthmoving operations.
Directly compatible with ZF WG200 transmissions found in Volvo L120H and L150H wheel loaders, as well as Champion 700A series motor graders, this pipe ensures uninterrupted oil delivery to the torque converter and planetary gear sets. It also fits select ERGOPOWER 8-speed variants used in Case 921E and New Holland W190C loaders.
Material & Durability
Fabricated from seamless cold-drawn steel with a zinc-nickel alloy coating, this pipe resists corrosion from aggressive hydraulic fluids and road salts. The double-flared ends are annealed to prevent stress cracking during installation, while the internal bore is deburred and phosphate-washed to eliminate particulate contamination risks. Each unit undergoes a 200-bar hydrostatic proof test to validate structural integrity under surge pressures.

By replacing worn or corroded oil lines with this genuine ZF-spec component, you eliminate the risk of pressure loss that leads to clutch slippage and premature planetary failure. The precision-bent geometry ensures a tool-free, interference-free fit within the transmission housing—critical for minimizing downtime in fleet maintenance environments.
