Titan part 235-027 is a piston seal designed to provide a dynamic seal between the piston and cylinder wall on compatible PowrTwin, PowrTex, and PowrLiner stripers and sprayers. This seal prevents fluid bypass around the piston, ensuring efficient pressure generation and consistent material flow. Replacing a worn, cut, or hardened piston seal restores pumping efficiency, eliminates pressure loss, and prevents costly fluid section damage.

The Titan 235-027 Piston Seal is an OEM dynamic seal that fits around the piston in the fluid section of a wide range of Titan industrial stripers and sprayers. It creates a high‑pressure barrier between the piston and cylinder wall, preventing material from bypassing the piston and ensuring efficient pumping.
Over time, piston seals wear due to friction, pressure cycles, and abrasive coatings. A worn or damaged seal allows fluid to leak past the piston, causing pressure drop, reduced output, and erratic spray performance. Replacing with genuine Titan 235-027 restores the original sealing efficiency, maximizes pump pressure, and extends the life of the fluid section.
| Pressure generation | Prevents fluid bypass around piston |
|---|---|
| Flow consistency | Maintains steady material output |
| Component protection | Reduces wear on cylinder wall |
| Visible wear or scoring | Seal surface damaged or worn thin |
|---|---|
| Hardening / cracking | Seal material brittle or cracked |
| Pressure loss | Sprayer cannot maintain rated pressure |
| During fluid section rebuild | Always replace seal when rebuilding pump |

When replacing the piston seal, consider inspecting or replacing these associated components.
Inspect the piston and cylinder wall for scoring; replace if damaged.
Replace the retainer screw (Titan 235-022) when rebuilding the fluid section.
Replace all packings and seals in the fluid section at the same time.
