The SprayTech 0288144 is a genuine OEM Complete Hopper Assembly for a family of air-assisted airless and aircoat sprayers. This assembly is the main material container for the sprayer, holding up to 1.6 gallons (6 liters) of paint, stain, or clear coat. It is designed as a direct replacement for the standard black 6-liter hoppers found on both older and newer machines.
This kit includes all components needed to replace a damaged or worn hopper. A cracked hopper, torn filter, or missing cover can lead to material spills, contamination, or improper operation. Replacing the entire assembly ensures a perfect fit, restores clean filtration, and provides a reliable seal for consistent material flow to the pump.

This assembly is marketed to replace all of the "black" 6-liter hoppers on both older and new units
Some older or different model sprayers may require an additional adapter to use this standard 6-liter hopper assembly.
For models like the 404+, 3566, or 435 that have a 3/4" water hose threaded inlet, this adapter valve is required to install the 0288144 hopper.
If the hopper is being replaced due to contamination, it is good practice to check and service the pump seals and filters downstream.
