253405 is a Spring Support used in the pump fluid section of compatible Elite and PowrLiner airless sprayers. It positions and supports the compression spring that maintains consistent pressure on the outlet valve assembly, helping to ensure proper sealing and reliable priming.

| Part Description | Spring Support |
| Brand | Elite / PowrLiner |

| Condition | New |
The 253405 Spring Support is a small but essential component inside the pump fluid section. It seats against the outlet valve spring, providing a stable base and maintaining correct spring compression. On compatible Elite 3000, 3500 and PowrLiner 3500/4500 sprayers, this support helps the outlet valve seal consistently under pressure and prevents spring misalignment or binding.
A cracked, deformed, or missing spring support can cause insufficient spring tension, leading to poor outlet valve sealing, pressure loss, erratic spray, or failure to prime. Replacing a damaged support restores proper valve operation and prevents unnecessary replacement of other fluid section components.
| Spring positioning | Keeps the outlet valve spring centered and properly seated |
|---|---|
| Consistent spring force | Ensures correct tension for valve sealing under pressure |
| Prevents binding | Stops spring from shifting sideways or contacting housing walls |
| Visible cracks or breakage | Support is split, missing a chunk, or deformed |
|---|---|
| Flattened / compressed | Support no longer holds its original shape or height |
| Corrosion or pitting | Surface damage that could weaken support or contaminate fluid |
| Rebuilding fluid section | Preventative replacement during major pump overhaul |

The spring support is often replaced during fluid section repairs. These parts are typically inspected or changed at the same time.
The spring support works directly with the outlet valve spring and seat.
Spring fatigue or loss of tension often accompanies support damage.
Both valves are commonly rebuilt together during pressure/priming issues.
