805-408 is a siphon tube assembly designed to draw paint from the container to the pump on compatible Impact and RentSpray sprayers. This rigid tube with an integrated strainer ensures a steady, clean fluid supply by filtering debris before it enters the pump. Replace a cracked, clogged, or damaged siphon tube to restore proper priming and prevent air from entering the system.
| Part Number | 805-408 |
|---|---|
| Part Description | Siphon Tube |
| Brand | Impact / RentSpray |
| Fits | Impact 400, 440, 640, X410, X440, X540I, 640I/IA; RentSpray 500, 600 Impact |
| Condition | New |
The 805-408 siphon tube is an OEM replacement component that draws coating material from the container to the pump on compatible Impact and RentSpray sprayers. This rigid tube extends into the paint pail and features an integrated strainer at the inlet to filter out debris that could clog the pump or spray tip.
Over time, siphon tubes can become cracked from flexing, clogged with dried material, or damaged during cleaning. A damaged siphon tube may cause air ingestion (sputtering), reduced material flow, or complete loss of prime. Replacing it with this genuine assembly ensures reliable material pickup and helps maintain consistent spray performance.
| Fluid delivery | Transfers paint from container to pump inlet |
|---|---|
| Debris filtration | Integrated strainer traps particles that could damage pump or tip |
| Prime maintenance | Helps pump stay primed by providing an airtight path |
| Cracks / breaks | Visible damage causing air ingestion or leaks |
|---|---|
| Clogged strainer | Debris buildup that cannot be cleaned, restricting flow |
| Loss of prime | Sprayer repeatedly loses prime; tube is suspected |
| Kinked / deformed | Tube shape distorted, affecting flow or fit |
Part 805-408 is designed for use on the following Impact and RentSpray models. Always verify fitment by consulting your machine's parts manual.

When replacing the siphon tube, inspect these associated fluid intake components to ensure complete system reliability.
Debris that passes a damaged siphon strainer can clog the inlet valve; clean or replace as needed.
Air leaks from a cracked tube can cause the pump to run dry, accelerating packing wear.
If debris enters the system, the main fluid filter may be clogged; check and clean it.
