The Titan 0278357 Fitting is a precision fluid connector designed for use in the hydraulic or material delivery system of the PowrLiner 550. It creates a reliable, leak‑tight connection between hoses, valves, or pump components, ensuring uninterrupted material flow and maintaining system pressure.
Over time, fittings can become damaged due to overtightening, vibration, corrosion, or exposure to aggressive coatings. A compromised fitting may cause leaks, pressure drops, or air ingestion, leading to erratic spray performance and material waste. Replacing the fitting restores a secure connection and ensures the sprayer operates at peak efficiency.

When replacing a fitting, inspect or replace these associated components to ensure a complete, reliable repair.
If the fitting was damaged, inspect the hose end for wear or deformation. Replace the hose if necessary.
Many fittings use sealing washers or O‑rings; replace these whenever the fitting is removed to ensure a leak‑free connection.
Inspect the mating port for thread damage or debris that could compromise the new fitting.
