Spray Cups

A spray cup (also called a paint cup or paint tank) attaches to a spray gun to hold paint, varnish or stain for controlled application. Gravity (overcup): mounts on top of the gun and feeds material by gravity — common with HVLP and detail work for low-pressure, precise atomization. Pressure-feed: connects to an external air or pressure source to force material into the gun, suited to high-output industrial and production use. Siphon/undercup: fits beneath the gun and draws material up by vacuum, often used in smaller pistols and medium-duty jobs. Check thread type, fittings and cup material (plastic, stainless steel, aluminium) for compatibility with your spray system and coatings.
