Part 703-137A is a replacement swivel fitting assembly used in the fluid delivery system of PowrTwin and PowrLiner airless sprayers. It connects the pump outlet to the hose while allowing rotational movement, reducing hose twist and operator fatigue. This assembly restores leak-free swivel action and reliable fluid flow when original fittings become worn or begin to leak.

The 703-137A swivel fitting assembly is a precision component that connects the pump outlet to the spray hose while allowing 360-degree rotation. This rotational freedom prevents hose kinking and twisting during operation, reducing strain on the hose and making the sprayer easier to maneuver. Designed for high-pressure airless applications, it maintains a leak-free seal even under continuous use.
Constructed from durable machined steel with integrated seals, this assembly withstands the abrasive and chemical nature of paints, stains, and coatings. When the original swivel becomes stiff, leaks, or fails to rotate smoothly, replacing it with part 703-137A restores ease of movement and prevents fluid drips that can create messes and safety hazards.
| Hose rotation | Allows full 360° movement to prevent twisting |
|---|---|
| Leak prevention | Maintains seal between stationary pump and moving hose |
| Operator comfort | Reduces effort required to position spray gun |
| Fluid leakage | Paint seeping from swivel joint during operation |
|---|---|
| Stiff rotation | Swivel no longer turns freely, causing hose drag |
| Visible wear | Corrosion, deformation, or damage to swivel housing |
| Intermittent spray | Air entering system due to failed swivel seals |
