Key Features
- Genuine OEM Construction — Manufactured to exact original specifications, with correct thread pitch and material grade for dependable sealing under operating pressure.
- Direct-Fit Replacement — Engineered to install in the same bulkhead position as the original, with matching hex dimensions for standard wrenching.
- Broad Fitment Coverage — Compatible with STX55Y6, STX55J6, WRSPUDF, WRS5200, and WRS5200DFPU models, covering both ride-on trowel and ride-on roller screed applications.
- Secure Fluid Circuit Integrity — A properly seated bulkhead jam nut fitting locks the line fitting firmly against the panel or housing, preventing movement, vibration loosening, and fluid leaks during operation.
- Leak Prevention Matters — A worn or missing bulkhead jam nut allows fittings to shift and rotate under pressure, which can cause fluid loss, hydraulic pressure drop, or damage to connected lines and components.
A bulkhead jam nut fitting is used to secure a fluid line or hydraulic passage through a panel, bulkhead, or housing wall. The nut threads onto the fitting body from the opposite side of the panel, clamping it firmly in place and preventing rotation or pullout under pressure and vibration. When this fitting loosens, backs out, or fails, the connected fluid line can shift or leak — disrupting hydraulic flow, contaminating surrounding components, or causing a complete loss of pressure in that circuit. Replacing a damaged or missing bulkhead jam nut fitting promptly keeps the fluid system sealed and performing as intended.
