Titan part 779-177 is a adapter used to connect or transition between different components on compatible PowrLiner airless stripers. This adapter may be used for fluid connections, mounting interfaces, or thread conversion (e.g., pump to hose, pressure transducer to manifold, or gun bar bracket). A cracked, stripped, or corroded adapter can cause leaks, misalignment, or component incompatibility. Replacing with the OEM adapter ensures proper fit, sealing, and system integrity.

The Titan 779-177 Adapter is a genuine OEM component designed to provide a secure mechanical or fluid connection between two incompatible interfaces on PowrLiner airless striping machines. Typical applications include adapting pump outlets to hose fittings, mounting pressure switches to manifolds, or converting thread types (NPT to metric, etc.).
Adapters can fail due to overtightening (cracking), corrosion from paint solvents, or thread damage from cross‑threading. A faulty adapter leads to leaks, pressure loss, or inability to assemble components correctly. Replacing with OEM Titan 779-177 ensures proper material compatibility (brass, steel, or plated) and exact thread specifications.
| Connects dissimilar threads | Converts between NPT, BSP, or straight threads |
|---|---|
| Changes port size | Reduces or increases fitting diameter |
| Redirects flow | Angled or swivel adapters for hose routing |
| Mounting interface | Attaches sensors or valves to pump manifold |
| Visible cracks | Stress fractures, especially near hex flats |
|---|---|
| Stripped threads | Threads damaged from cross‑threading or over‑tightening |
| Corrosion / pitting | Heavy rust or chemical attack weakening the metal |
| Persistent leak | Leak at adapter threads even after fresh sealant |

When replacing an adapter, inspect these associated components.
Mating fitting may have damaged threads or sealing surface.
If the adapter uses a face seal, replace the O‑ring simultaneously.
Fresh PTFE tape or pipe dope ensures leak‑free assembly.
