AirSpray HVLP / SprayTech part 0093865 is a return tube designed to route excess material back to the supply container on compatible sprayer models. This tube is part of the circulation system that maintains consistent material flow and prevents pressure buildup. Replacing a cracked, kinked, or damaged return tube ensures proper material recirculation and reliable sprayer performance.

The 0093865 Return Tube is a flexible conduit that routes excess coating material from the sprayer back to the supply container on compatible AirSpray HVLP and SprayTech models. It is an essential component of the circulation system, helping to maintain consistent material flow and prevent pressure buildup.
In circulating spray systems, material is continuously pumped from the supply container to the spray gun and back. The return tube completes this loop, allowing excess material that is not sprayed to return to the container. This circulation keeps the material at proper viscosity, prevents settling, and ensures immediate availability at the gun. The tube must be flexible to accommodate movement while being resistant to chemicals and abrasion.
Over time, return tubes can become cracked from material exposure, kinked from improper routing, or clogged with dried coating. A damaged return tube can disrupt circulation, causing pressure fluctuations, material starvation at the gun, or spills. Replacing a worn or damaged return tube restores proper material circulation and ensures consistent spray performance.
| Material recirculation | Returns excess material to the supply container |
|---|---|
