The Wacker Neuson is a genuine OEM #4 ORFS Bulkhead Fitting designed for the RD16-90 and RD16-100 tandem roller series, as well as the CRT60-74L ride-on concrete trowel. As a genuine OEM component, is manufactured to the exact material grade, thread form, and dimensional tolerances of the original part — ensuring a leak-free hydraulic connection from day one. This fitting is confirmed across multiple machine configurations including the RD16-90 Vibratory Roller, the RD16-90 Hydrostatic Vibratory Roller, the RD16-100 Hydrostatic Vibratory Roller, and the CRT60-74L. Keeping your hydraulic system properly sealed with the correct fitting helps maintain consistent pressure delivery and protects downstream components from contamination or fluid loss.
Key Features
- O-Ring Face Seal Integrity — ORFS thread form provides a metal-to-metal seating surface with an O-ring face seal, delivering superior leak resistance compared to standard JIC or NPT fittings under high hydraulic pressure cycles.
- Genuine OEM Tolerancing — Sourced directly from Wacker Neuson, this fitting meets the exact thread pitch, port size, and body geometry of the original hydraulic circuit design — no re-machining or adapter workarounds needed.
- Bulkhead Configuration — The bulkhead design allows the fitting to pass through and lock into a panel or bulkhead wall, routing hydraulic lines cleanly through the machine frame without abrasion or routing stress.
- Broad Model Coverage — Fits multiple RD16-90 and RD16-100 tandem roller configurations, plus the CRT60-74L ride-on concrete trowel, covering a range of Wacker Neuson compaction and finishing equipment.
- Hydraulic System Protection — A correctly seated bulkhead fitting prevents fluid bypass and pressure drop; a failed or cross-threaded fitting can starve hydraulic actuators of flow, causing sluggish or unresponsive machine behavior.
A bulkhead fitting is a hydraulic connector designed to mount through a wall, panel, or frame member, securing with a locknut so that hydraulic lines can be routed from one side to the other in a clean, fixed position. The #4 ORFS (O-Ring Face Seal) designation means the fitting seals against a machined flat face using a captured O-ring, which virtually eliminates the weeping and micro-leaks common in tapered thread fittings under vibration — exactly the conditions present in roller and trowel operation. When this fitting cracks, cross-threads, or loses its O-ring, hydraulic fluid can escape the circuit, leading to reduced clamping or drive force, potential contamination of surrounding components, and unsafe operating conditions.
