Wacker Neuson 5000164349 90-Degree 12 Barb 8 Orb Custom Fitting

The Wacker Neuson is a genuine OEM 90-Degree 12 Barb 8 Orb Custom Fitting designed for the RD12, RD16, and CB14B series tandem and vibratory rollers. As a factory-sourced hydraulic fitting, part is manufactured to the exact geometry and thread specification required by the original hydraulic circuit, ensuring a leak-free connection every time. This fitting is confirmed for use across a wide range of RD12, RD16, and CB14B machine configurations, including foldable ROPS, hydrostatic, and solid-ROPS variants. Sourcing the correct OEM fitting eliminates the guesswork of cross-referencing aftermarket alternatives and protects the integrity of your machine's hydraulic system.

Key Features

• OEM Thread and Barb Geometry — Machined to the exact No. 12 barb and No. 8 ORB thread dimensions specified for the original hydraulic circuit, preventing cross-threading or fitting mismatch.
• 90-Degree Elbow Design — The right-angle configuration routes hose runs cleanly within tight machine compartments, maintaining the original routing path without forced bends or stress on adjacent hose ends.
• Broad RD and CB14B Series Coverage — Confirmed fitment across RD12-90, RD12A-90, RD16-90, RD16-100, CB14B-900, and CB14B-1000 configurations, including hydrostatic and foldable ROPS variants.
• Leak-Free Hydraulic Connection — A properly seated ORB seat and correctly sized barb retain system pressure and prevent hydraulic fluid loss that would otherwise cause erratic drum drive or steering response.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000164349 carries the same quality standard as the fitting installed at the factory, with no risk of dimensional drift common to generic substitutes.

A hydraulic fitting of this type serves as a transition connector within the machine's hydraulic plumbing, changing the flow direction by 90 degrees while bridging two different connection standards — in this case, a No. 12 hose barb on one end and a No. 8 O-Ring Boss (ORB) port on the other. In tandem rollers and vibratory compactors, maintaining sealed, correctly routed hydraulic connections is essential to sustaining consistent drum drive pressure and smooth propulsion control. When a fitting of this type leaks, cracks, or is replaced with an incorrect size, the result can be pressure drop, fluid contamination, or hose failure that takes the machine out of service entirely.
