The Wacker Neuson is a genuine OEM Straight Fitting #12 Orb Jic designed for RD27-100 and RD27-120 series ride-on tandem rollers. As a direct factory replacement, this fitting maintains the hydraulic connection integrity that the RD27 platform depends on for consistent compaction performance. It is compatible across the full RD27 family, including Pro and Basic Tier 4 Final variants, covering both 100 cm and 120 cm drum-width configurations. When you need an exact match for the original fitting, part number is the confirmed OEM solution.
Key Features
- OEM-Rated Hydraulic Sealing — Manufactured to the same thread form and sealing geometry as the original, ensuring a leak-free connection at the ORB (O-Ring Boss) to JIC (37° flare) interface without relying on thread sealant alone.
- Straight-Body Configuration — The straight profile allows direct inline hose or tube routing where inline fittings are required, simplifying reinstallation in tight hydraulic circuit spaces on the RD27 frame.
- Broad RD27 Family Coverage — Fits RD27-100 and RD27-120 tandem rollers across multiple machine numbers, including Pro and Basic Tier 4 Final builds, so one part number covers a wide range of units in your fleet.
- Hydraulic Circuit Reliability — A correctly seated fitting keeps the hydrostatic drive circuit at operating pressure, supporting smooth drum rotation, consistent vibration output, and responsive travel control on the RD27.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this fitting carries the same part number used in original machine assembly, eliminating compatibility guesswork at the point of repair.
A straight ORB-to-JIC hydraulic fitting serves as a fixed connection point in the machine's hydraulic plumbing, joining an O-Ring Boss port — typically found on pumps, motors, or manifolds — to a JIC flared tube or hose end. The ORB end seals against a machined seat using a compressed O-ring, while the JIC end relies on a metal-to-metal 37° flare cone for a pressure-tight seal. On ride-on tandem rollers like the RD27, these fittings are load-bearing nodes in the hydrostatic drive and vibration circuits; a worn, cracked, or improperly sealed fitting can cause hydraulic fluid loss, pressure drop, and loss of drive or vibration function, bringing compaction work to a halt.
