Part number 0508124 is a Lid with Gasket assembly designed to seal the fluid cup on the SprayTech HVLP Maxum II spray gun. The lid securely fastens to the cup, while the integrated gasket creates a leak-proof and air-tight seal. This seal is critical for maintaining the correct air pressure balance inside the cup, which allows material to feed smoothly into the gun.
A damaged, warped, or missing lid, or a worn-out gasket, can cause material to leak from the cup, allow air leaks that disrupt material flow, or permit contaminants to enter the fluid. Replacing the lid assembly restores a proper seal for clean and efficient operation.
| Leak Prevention | Seals the cup to prevent material from spilling or leaking out |
|---|---|
| Pressure Seal | Maintains air pressure inside the cup for consistent fluid feed |
| Contamination Barrier | Keeps dirt and debris out of the material during use |
| Visible Leaks | Material seeps out from under the lid during spraying |
|---|---|
| Poor Seal | Lid will not tighten securely or feels loose on the cup |
| Gasket Failure | Gasket is cracked, torn, hardened, or permanently flattened |
| Physical Damage | Lid is cracked, warped, or has broken lugs or threads |
Part number 0508124 is designed specifically for the fluid cup used with the SprayTech HVLP Maxum II spray gun. Always confirm fitment using the correct parts diagram for your exact model.

The lid and gasket are part of the fluid cup assembly. These related components are often inspected or replaced to ensure the entire cup system functions properly.
The cup itself must be free of cracks or damage for the lid to seal correctly.
Some models have a separate gasket that seals the cup to the gun body, which should also be checked.
The lid often contains a small air vent or valve. If clogged, it can cause poor material flow.
