The 813-555 Fitting is a factory-specified connector used in the fluid or hydraulic pathways of select Titan and Wagner airless sprayers. Proper sealing at these connection points is critical for maintaining system pressure, preventing leaks, and ensuring consistent spray output.
A worn, damaged, or improperly sealed fitting can lead to pressure loss, fluid leakage, or air intrusion into the system. Replacing the fitting restores proper sealing and helps protect adjacent hoses, valves, and pump components.
| Fluid connection | Joins hoses, tubes, or components within the fluid circuit |
