The Multiquip 16598 Fitting Nut 10 Blkhd Jam is a genuine OEM component designed for Whiteman ride-on roller screed models including the WRS5200DFPU, WRS5200, and WRSPUDF. Sourced directly through Multiquip's authorized parts supply, this fitting delivers an exact match to the original hardware installed at the factory. Verified compatibility across the WRS ride-on roller screed lineup makes 16598 a confident choice when restoring hydraulic or fluid line connections on your machine.
Key Features
- Genuine OEM Construction — Machined to the same thread form and material grade as the original fitting, ensuring a secure, leak-free bulkhead connection every time.
- Direct Bolt-In Replacement — Matches the original 10-series bulkhead jam nut specification, threading directly onto existing bulkhead fittings without rework or modification to the port or panel.
- Confirmed Fitment for WRS Roller Screeds — Verified for the WRS5200DFPU, WRS5200, and WRSPUDF ride-on roller screed models.
- Maintains Line Integrity — A properly torqued bulkhead jam nut locks the fitting securely through the panel, preventing rotation and maintaining a pressure-tight seal under continuous screed operation.
- Fluid System Safety — A loose or missing bulkhead jam nut can allow fittings to back out under vibration, leading to fluid leaks that create slip hazards and potential hydraulic system damage — replacing it promptly matters.
A bulkhead jam nut is used to secure a fitting through a panel or housing wall, locking it in place so the connection point cannot rotate or pull through under pressure or vibration. On ride-on roller screeds like the WRS series, these fittings are typically part of the hydraulic or fluid routing system that keeps the roller drive and propulsion circuits operating correctly. When a bulkhead jam nut loosens or fails, the fitting can shift or leak, disrupting fluid flow and potentially causing damage to connected lines or downstream components.
