Overview
The ZF 2095.247.021 TUBE is a precision-engineered OEM genuine hydraulic conduit designed for heavy-duty construction machinery transmissions. This tube serves as a critical fluid transfer channel within the transmission housing, directing pressurized oil to the clutch packs and lubrication circuits. As an integral component of the hydraulic control system, it ensures consistent oil flow for gear engagement and thermal management. The SKU 2095.247.021 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-free seal and long service life in demanding off-road applications. When replacing this tube, it is common to also inspect the 5838109007: DIFFERENTIAL for wear, as both components share the same hydraulic circuit.
Symptoms of Failure
- External oil leaks around the transmission housing – A cracked or corroded ZF 2095.247.021 tube will drip transmission fluid, leaving puddles under the vehicle. This is a common sign of tube fatigue in WG-series transmissions.
- Delayed or harsh gear engagement – When the tube loses internal pressure due to a fracture, clutch packs receive insufficient oil, causing slipping or jerky shifts during acceleration.
- Overheating transmission fluid – A restricted or deformed tube reduces oil flow to the cooler, leading to elevated operating temperatures and potential damage to internal seals.
- Erratic hydraulic pressure readings – Fluctuating pressure on the gauge often points to a blocked or leaking tube, requiring immediate replacement of part 2095.247.021.

Compatibility
This tube is engineered for ZF WG-series powershift transmissions commonly found in construction equipment. It is a direct fit for the WG180, WG200, and WG250 models used in wheel loaders, graders, and dump trucks. The 2095.247.021 tube also integrates with the 0750117075: TAPER ROLLER BEARING assembly and the 2095209019: DIFFERENTIAL unit, ensuring proper oil distribution to the differential housing. For complete overhaul, consider pairing this tube with a 0631329086: SPRING PIN to secure mounting brackets.
