The 490-043 swivel union is a specialized fluid connection fitting that allows rotational movement between connected components while maintaining a pressure-tight seal. This component consists of two parts that rotate independently, preventing hose twisting, reducing stress on connections, and providing flexible fluid pathways during equipment movement and operation across multiple equipment platforms.
A damaged or leaking swivel union can cause fluid leakage, restrict fluid flow, create hose twisting that leads to premature failure, or limit equipment mobility. Replacing a faulty swivel union restores proper fluid connectivity, prevents hose damage, and ensures unrestricted equipment movement during spraying operations.
| Rotational freedom | Allows independent rotation between connected fluid components |
|---|---|
| Hose protection | Prevents twisting and kinking of connected hoses during movement |
| Sealed connection | Maintains leak-free fluid passage while allowing component movement |
| Fluid leakage | Visible fluid seepage from the swivel connection during operation |
|---|---|
| Restricted movement | Swivel action becomes stiff, seized, or fails to rotate freely |
| Physical damage | Cracks, deformation, or thread damage compromising the fitting |
| Internal wear | Excessive play or looseness in the swivel mechanism |
Part 490-043 is compatible with the following equipment models. Always confirm fitment using appropriate technical documentation for your specific application.
| Equipment Model | Component |
|---|---|
| PowrLiner 4955 | Swivel Union |
| PowrLiner 6955 | Swivel Union |
| PowrLiner 8955 | Swivel Union |
