Titan part 424-255 is a spring retainer used in the pump valve assembly of compatible PowrLiner airless stripers. This component secures the valve spring in position, ensuring proper spring tension and consistent valve operation. Replacing a worn, cracked, or deformed spring retainer restores correct valve seating and prevents spring misalignment.

The Titan 424-255 Spring Retainer is a critical component that holds the valve spring in its correct position within the pump valve assembly. On compatible PowrLiner stripers, this retainer ensures consistent spring tension, allowing the valve ball to seat and unseat properly during each pump cycle.
Over time, the spring retainer can crack, deform, or wear due to repeated impact and spring pressure. A damaged retainer can allow the spring to shift, leading to weak valve sealing, pressure loss, erratic operation, or premature failure of the valve ball and seat. Replacing the retainer restores proper spring alignment and valve function.
| Function | Description |
|---|---|
| Spring positioning | Holds the valve spring securely in its correct orientation |
| Consistent tension | Ensures the spring applies proper force to the valve ball |
| Valve timing | Maintains correct opening/closing sequence of the check valve |
| Symptom | Indication |
|---|---|
| Visible cracks / breakage | Retainer shows stress fractures or is in multiple pieces |
| Deformation | Retainer is bent, warped, or no longer holds spring tightly |
| Intermittent pressure loss | Sprayer loses pressure randomly due to spring shifting |
| Unusual noise | Rattling or clicking from valve area indicates loose components |

Valve assembly issues often involve multiple components. When replacing the spring retainer, these parts are commonly inspected or replaced at the same time.
The spring can weaken or break over time – replace with the retainer for consistent tension.
A worn ball will not seal properly even with a new retainer and spring.
Inspect the seat for grooves or pitting when servicing the valve assembly.
