Part 872-431 is a replacement bulkhead nut used to secure fluid connections through panels and manifolds on compatible spray equipment. This nut fastens fittings, gauges, or hose connections that pass through a bulkhead, creating a leak-proof seal. When the original nut becomes corroded, stripped, or damaged, replacement restores proper sealing and prevents fluid leaks.

The 872-431 bulkhead nut is a direct replacement fastener for securing fluid connections through panels on Hydra M, Hydra Pro Super, Hydra Pro 2000_4000, and 0528925N_2000_4000 equipment. This nut threads onto bulkhead fittings, gauges, or hose adapters that pass through a mounting surface, compressing seals to prevent fluid leaks. Manufactured from corrosion-resistant materials, it withstands exposure to paints, solvents, and pressure cycles. A damaged or corroded bulkhead nut can lead to leaks, loss of pressure, or fitting loosening during operation. Replacement restores the integrity of fluid connections and ensures safe operation. The hex design allows installation with standard wrenches. Regular inspection of bulkhead fittings during maintenance helps identify nuts requiring replacement before leaks develop.
| Fitting retention | Secures bulkhead fittings, gauges, and adapters to panels |
|---|---|
| Seal compression | Compresses o-rings or gaskets to prevent fluid leaks |
| Vibration resistance | Maintains tightness under equipment vibration |
| Stripped threads | Nut will not tighten properly on bulkhead fitting |
|---|---|
| Corrosion damage | Rust has weakened nut or made removal difficult |
| Fluid leakage | Leak at bulkhead connection due to insufficient clamping |
| Deformed hex | Corners rounded, wrench cannot get good grip |
