Titan part 759-014 is a block cover (also known as a manifold cover or access plate) used on compatible PowrLiner airless stripers. This cover seals an opening in the pump manifold, valve block, or fluid housing, protecting internal components from debris and preventing fluid leaks. A cracked, warped, or missing block cover can cause paint leakage, pressure loss, or contamination of internal passages. Replacing with the OEM cover restores proper sealing and system integrity.

The Titan 759-014 Block Cover is a genuine OEM cover plate designed to seal access ports or cavities in the pump manifold, valve block, or hydraulic housing on compatible PowrLiner airless stripers. It is typically secured with screws or bolts and includes a gasket or O‑ring sealing surface.
Over time, block covers can crack from overtightening, freeze damage (if water remains in the system), or impact. A damaged cover allows paint to leak externally, draws air into the fluid section (causing loss of prime), or allows debris to enter internal passages. Replacing the cover with OEM Titan 759-014 ensures correct material thickness, flatness, and sealing.
| Seals access ports | Prevents fluid leaks from manifold or valve block |
|---|---|
| Protects internals | Keeps debris out of pump or valve chambers |
| Maintains pressure | Contains system pressure within the fluid section |
| Service access | Allows removal for cleaning or component replacement |
| External paint leak | Paint seeps from cover edge even after tightening |
|---|---|
| Visible cracks or warping | Cover is no longer flat or has stress fractures |
| Loss of prime / air ingestion | Pump loses prime repeatedly, possibly from warped cover |
| Missing or damaged screw holes | Stripped threads or broken ears on the cover |

When replacing the block cover, inspect these associated components.
Always replace the sealing element with the cover to ensure leak‑free installation.
Corroded or stripped screws should be replaced to achieve proper torque.
Inspect the mating surface for nicks, corrosion, or cracks that could affect sealing.
