ProFinish 773-140 Quart Cup Assembly

The ProFinish 773-140 Quart Cup Assembly is a professional HVLP spray gun fluid cup system designed to provide smooth and consistent material delivery during fine finishing applications. Commonly used with Titan ProFinish and CAPSpray systems, this quart cup assembly helps maintain reliable coating flow for spraying lacquers, stains, sealers, enamels, urethanes, and other fine-finish materials.

This assembly includes essential OEM components such as the cup lid, solvent-resistant gasket, lock bracket, lock cam, flex tube, air supply tube, check valve, barb weight, and mesh screen. These parts work together to maintain proper suction, secure sealing, and uninterrupted fluid transfer while spraying at different angles.

Main Assembly Components

The 773-140 Quart Cup Assembly is designed for durability and dependable HVLP performance in woodworking shops, cabinetry projects, furniture finishing, and commercial coating applications.

Proper cleaning and routine maintenance help reduce clogging, air leaks, and inconsistent spray patterns while extending the life of the spray system.

FAQs

Loss of suction is usually caused by a clogged flex tube, damaged gasket, loose lid connection, or blocked screen filter inside the cup assembly.

Sputtering often occurs when air leaks develop around the cup lid gasket or when the fluid pickup tube becomes partially restricted by dried coating material.

The Titan 770-715 check valve helps maintain proper airflow balance inside the cup assembly. A worn or clogged valve can disrupt fluid delivery and affect atomization consistency.

Yes. A cracked, hardened, or clogged Titan 773-172 Flex Tube can restrict coating pickup, leading to uneven spray patterns and inconsistent fluid flow during operation.

Leaks around the lid are commonly caused by a worn Titan 770-584 solvent gasket, improper lid tightening, or debris on the sealing surface that prevents an airtight seal.
