Titan part 235-022 is a piston retainer screw used to secure the piston assembly within the fluid section of compatible PowrLiner, PowrTex, and PowrTwin airless sprayers. This screw locks the piston to the connecting rod or retains the piston within the cylinder. A stripped, broken, or missing retainer screw can cause piston disengagement, loss of pressure, or catastrophic pump failure. Replacing with the OEM screw ensures proper piston retention and safe, reliable pump operation.

The Titan 235-022 Piston Retainer Screw is a genuine OEM fastener that secures the piston to the connecting rod or retains the piston within the pump cylinder on PowrLiner, PowrTex, and PowrTwin airless sprayers. It is a critical component that withstands high reciprocating forces during pump operation.
Over time, the retainer screw can become stripped from over‑torquing, corroded from chemical exposure, or broken due to metal fatigue. A failed screw allows the piston to detach, causing sudden loss of pressure, loud knocking, or complete pump seizure. Replacing with OEM Titan 235-022 ensures proper thread engagement, correct clamp force, and safe, reliable pump function.
| Secures piston to connecting rod | Prevents piston from detaching during operation |
|---|---|
| Maintains alignment | Keeps piston centered in cylinder bore |
| Withstands high forces | Handles reciprocating loads without loosening |
| Safety critical | Prevents catastrophic pump failure |
| Stripped threads | Screw spins without tightening |
|---|---|
| Visible damage | Bent, cracked, or severely corroded screw |
| Loss of piston retention | Piston moves or knocks during pump operation |
| During pump rebuild | Always replace the retainer screw when rebuilding the pump |
