Titan part 779-118 is an OEM replacement block (manifold / mounting block) used on compatible PowrLiner airless stripers. This component serves as a fluid or mounting interface – typically between the pump, pressure transducer, or hose connections. A cracked, warped, or stripped block can cause leaks, pressure loss, or component misalignment. Replacing with genuine OEM block restores proper sealing and system integrity.

The Titan 779-118 Block-OEM is a genuine manufacturer replacement block used in the fluid or mounting system of compatible PowrLiner airless stripers. Depending on the specific application, this block may function as a manifold, a pump mount, a pressure transducer adapter, or a hose connection hub.
Over time, blocks can crack from overtightening, freeze damage (if water is left in the system), or simple material fatigue. A damaged block typically causes external leaks, loss of spraying pressure, or inability to properly secure connected components. Replacing with the OEM Titan 779-118 block ensures correct fit, port alignment, and sealing surface integrity.
| Fluid routing | Directs paint flow between pump, hose, and pressure sensor |
|---|---|
| Mounting interface | Secures pump, transducer, or filter assembly to frame |
| Sealing surface | Provides flat, machined surfaces for O‑ring or gasket seals |
| Port connections | Accepts threaded fittings for hoses and adapters |
| Visible cracks | Cracks in casting, especially near threaded ports |
|---|---|
| Persistent external leaks | Leak at block mating surface after new O‑ring/gasket |
| Warped mounting face | Block no longer flat, causing poor seal |
| Stripped threads | Internal threads damaged from overtightening |

When replacing the block, inspect these associated sealing and mounting components.
Always replace sealing rings between block and pump/transducer to prevent new leaks.
Corroded or stretched fasteners can cause uneven clamping and block fracture.
If the block cracked near the transducer port, inspect the transducer for damage.
