Wacker Neuson 5000155047 Bulkhead Fitting St #8 Orfs

The Wacker Neuson is a genuine OEM Bulkhead Fitting St #8 Orfs designed for the RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 vibratory trench roller series, as well as WB16A series power buggies. As a direct factory replacement, part is manufactured to the same specifications as the original component installed at the factory. This fitting is compatible across a wide range of RT-series trench roller configurations, including smooth-drum and EU variants, making it a versatile stocking part for fleets running multiple machine variants.

Key Features

• Genuine OEM Hydraulic Integrity — Manufactured to exact thread form and sealing geometry for #8 ORFS connections, ensuring leak-free hydraulic line termination at the bulkhead.
• Straight-Port ORFS Design — The straight (#8 ORFS) configuration provides a flush, vibration-resistant connection that installs directly into the existing bulkhead port without reworking the hydraulic line.
• Broad RT-Series Compatibility — Fits RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 vibratory trench rollers across standard and EU configurations, plus WB16A series power buggies.
• Maintains Hydraulic System Pressure — A correctly seated ORFS bulkhead fitting holds system pressure and prevents fluid loss that would otherwise cause sluggish or non-responsive hydraulic actuation.
• Hydraulic Fluid Containment — A failing or improperly rated fitting risks uncontrolled hydraulic fluid release under pressure — using the correct OEM part eliminates that risk at this connection point.

A bulkhead fitting is used to route a hydraulic line through a panel or structural wall of the machine, sealing the penetration point and maintaining the integrity of the hydraulic circuit on both sides. The #8 ORFS (O-Ring Face Seal) thread standard creates a positive, metal-to-metal seal backed by an O-ring at the face of the fitting, which resists loosening under vibration — a critical property on compaction equipment like trench rollers. When this fitting corrodes, cracks, or loses its O-ring seal, hydraulic pressure at that circuit drops, leading to reduced drive or compaction performance and potential fluid contamination of the surrounding area.
