3M Paint Prep System 28 oz. Pressure Cup with Hose
The 3M Paint Preparation System 28 oz. Pressure Cup with Hose is a large-capacity pressure-fed cup built for full-panel and full-hull spray work. The integrated pressure hose port connects to a compressed air supply to push material through the gun at a consistent rate, maintaining steady flow regardless of gun angle — including overhead and inverted positions.
At 28 oz., this cup holds significantly more material than the compact 6 oz. version, making it the right choice when you need to cover large areas without stopping to refill. The pressure-feed design is particularly effective for higher-viscosity coatings that benefit from positive pressure rather than gravity alone.
Key Features
- 28 oz. capacity — large volume for full-panel and full-hull applications
- Integrated pressure hose port for pressure-fed spray gun operation
- Pressure-feed design maintains consistent material flow at any gun angle
- Suited for higher-viscosity coatings that benefit from positive pressure feed
- Compatible with 3M PPS pressure-feed spray gun setups
Best Use Cases
- Full-hull, full-panel, and large-area paint jobs requiring high-volume continuous spray
- Higher-viscosity primers, antifouling coatings, and topcoats that perform better under pressure feed
- Overhead and inverted spraying where gravity-feed cups lose flow consistency
- Production environments where minimizing refill stops improves throughput
Parts Desk Insights
This is the large-volume pressure-fed option in the PPS cup lineup. For smaller touch-up and detail work, the 6 oz. Pressure Cup with Hose is the compact alternative. If you’re running a gravity-feed setup instead, the Large Cup & Collar paired with the Large Lids & Liners Kit is the right direction. For the spray gun this cup pairs with, see the 3M Performance Spray Gun. Confirm hose fitting compatibility with your gun before ordering.
