Wacker Neuson 5000164347 90-Degree 1/4-19 BSPP #6 ORFS Fitting

The Wacker Neuson is a genuine OEM 90-Degree 1/4-19 BSPP #6 ORFS Fitting designed for the RD16-90 and RD16-100 series tandem vibratory rollers. Sourced directly from Wacker Neuson, this fitting ensures the exact thread form, sealing geometry, and bend angle required by the hydraulic circuit on these machines. Confirmed fitment spans multiple RD16-90 and RD16-100 configurations, including hydrostatic drive variants. When you match the OEM part number, you eliminate the guesswork of finding a compatible hydraulic adapter in the field.

Key Features

• Correct Thread Pairing for the Hydraulic Circuit — Transitions a 1/4-19 BSPP port to a #6 ORFS connection at a 90-degree angle, matching the original routing in the RD16 hydraulic system exactly.
• Genuine OEM Construction — Manufactured to Wacker Neuson specifications with the thread form, wall thickness, and sealing face finish required to hold pressure in a vibratory roller's hydraulic circuit without weeping or work-loosening.
• RD16-90 and RD16-100 Series Coverage — Verified for RD16-90 standard and hydrostatic configurations as well as the RD16-100 tandem roller, covering both gasoline and hydrostatic drive builds across multiple machine serial ranges.
• Leak-Free Hydraulic Routing — A properly seated ORFS face-seal fitting prevents hydraulic fluid loss that would otherwise cause pressure drop, erratic drum drive response, or compaction inconsistency on asphalt and soil surfaces.
• Hydraulic System Integrity — Hydraulic fittings on roller drive circuits are pressure-rated components; using the correct OEM fitting with the proper sealing face helps prevent uncontrolled fluid release under operating pressure.

A 90-degree hydraulic fitting serves as a directional transition point in a machine's hydraulic plumbing, allowing hoses and lines to change angle without bending the hose itself under stress. On a tandem vibratory roller like the RD16 series, these fittings connect key hydraulic lines — such as those serving the drum drive motors or vibration circuits — where straight fittings would conflict with surrounding components. The BSPP-to-ORFS configuration on the 5000164347 bridges two common hydraulic thread standards, with the ORFS face-seal end providing a metal-to-metal seating surface that resists leaks under the vibration and pressure cycling inherent to roller operation. When a fitting like this cracks, corrodes, or strips, hydraulic pressure to the affected circuit drops and the roller may lose drive response or vibratory function entirely.
