The Wacker Neuson ORFS Fitting BH E90 06 ST is a genuine OEM hydraulic fitting designed for the RT560 and RT820 vibratory trench roller series. Sourced directly from Wacker Neuson, this fitting carries the same part number and specification as the original component installed at the factory. It is confirmed to fit across multiple RT560 and RT820 machine configurations, including the RT820HT variant. When hydraulic fittings wear, corrode, or develop leaks, maintaining the correct thread form and sealing geometry is critical — and this genuine OEM part delivers exactly that.
Key Features
- Genuine OEM Sealing Integrity — ORFS (O-Ring Face Seal) design provides a metal-to-metal contact surface with an O-ring seat, delivering leak-free hydraulic connections that standard JIC or flare fittings cannot replicate in this application.
- Exact Hydraulic Port Match — machined to the original thread pitch, port size, and elbow angle (E90) specified for the RT560 and RT820 hydraulic circuit, ensuring a direct installation with no adapters or modification.
- Broad RT Series Coverage — compatible with RT560 and RT820 vibratory trench rollers across multiple machine configurations, including the RT820HT high-torque variant.
- Sustained Hydraulic System Performance — a failed or leaking ORFS fitting starves downstream hydraulic components of pressure, leading to sluggish drum drive response or complete loss of trench roller function; replacing with a correct-spec fitting restores full system pressure.
- Pressure System Safety — hydraulic fittings operating at high working pressures must meet the original port and seal specification; using an incorrect fitting risks sudden hydraulic failure and potential injury to the operator.
An ORFS fitting uses a flat-faced port with a machined groove that seats an O-ring, creating a positive face seal when the fitting is torqued. This design is preferred in high-pressure hydraulic systems because it virtually eliminates the leak paths that tapered or flare-style fittings can develop over time. The BH E90 06 ST designation indicates this is a bulkhead-style, 90-degree elbow fitting in a size 6 configuration with straight threads — exactly as specified for the hydraulic plumbing on the RT560 and RT820 trench roller platforms. A damaged or leaking fitting at this junction will cause hydraulic fluid loss, pressure drop, and ultimately prevent the trench roller from compacting effectively, making prompt replacement essential to keeping the machine operational on the trench line.
