The Wacker Neuson is a genuine OEM St.Bspp1/8-#4 Orfs Fitting designed for the RD16-90 and RD16-100 tandem vibratory rollers and CB14B-900 and CB14B-1000 series soil and asphalt compaction rollers. Sourced directly from Wacker Neuson, this fitting carries the exact thread form, port sizing, and sealing geometry specified for the original hydraulic circuit. It is compatible across multiple machine configurations including standard hydrostatic and IRH variants of the RD16-90 and RD16-100, as well as the full CB14B family.
Key Features
- OEM-Correct Thread and Port Specification — Machined to the precise BSPP 1/8 and ORFS #4 dimensions required to maintain leak-free hydraulic connections in the original circuit.
- Direct Hydraulic Line Replacement — Matches the original port orientation and thread engagement, so the fitting seats correctly without rework to surrounding lines or adapters.
- Broad Roller Family Coverage — Fits RD16-90 (including hydrostatic and tandem configurations), RD16-100, and CB14B-900 and CB14B-1000 variants used in soil and asphalt compaction applications.
- Hydraulic Integrity Under Working Pressure — A correctly installed fitting maintains system pressure and flow across the hydraulic drive circuit; a damaged or cross-threaded fitting can cause fluid loss, pressure drop, and compaction performance degradation.
- Genuine Wacker Neuson Part — Supplied as genuine OEM, ensuring the part number 5000165283 matches the approved component specification for these roller models.
An ORFS (O-Ring Face Seal) fitting creates a hydraulic connection that seals against the flat face of the mating port using a captive O-ring, rather than relying on thread engagement alone for sealing. This design resists vibration-induced loosening and is well suited to the high-cycle operating environment of a vibratory roller. The BSPP (British Standard Parallel Pipe) thread profile on this fitting engages the port threads for secure retention while the face seal does the work of preventing fluid loss. When this fitting is cracked, cross-threaded, or worn, the result is typically an external hydraulic leak that can starve the drive circuit and compromise the roller's compaction output.
