Titan part 235-030 is a cylinder head plug designed to seal access ports or threaded openings in the fluid cylinder head on compatible PowrTwin, PowrTex, and PowrLiner stripers and sprayers. This plug prevents fluid leakage, maintains system pressure, and keeps contaminants out of the cylinder bore. Replacing a damaged, stripped, or missing cylinder head plug restores a leak‑tight seal, prevents pressure loss, and protects internal pump components.

The Titan 235-030 Cylinder Head Plug is an OEM threaded plug used to seal access ports, pressure test points, or unused openings in the cylinder head of Titan industrial pumps. It is manufactured to precise thread specifications and material standards to withstand high pressure and chemical exposure.
Over time, cylinder head plugs can become cross‑threaded, corroded, or damaged during removal. A leaking or missing plug causes fluid to escape, leading to pressure drop, material waste, and potential safety hazards. Replacing with genuine Titan 235-030 restores a leak‑tight seal, maintains system pressure, and prevents contamination of the fluid section.
| Port sealing | Closes access holes in cylinder head |
|---|---|
| Pressure retention | Prevents fluid leakage |
| Contaminant exclusion | Keeps dirt out of fluid section |
| Leakage | Fluid weeping from plug area |
|---|---|
| Cross‑threaded / stripped | Plug will not tighten properly |
| Corrosion | Rust or chemical attack |
| Missing plug | Plug lost during service |

When replacing the cylinder head plug, consider inspecting or replacing these associated components.
If the plug uses a sealing washer or O‑ring, replace it at the same time.
Inspect the threaded hole for damage; repair or replace the head if threads are stripped.
If the plug was leaking, consider a full fluid section rebuild.
