Graco SG3 vs TrueCoat 360
Pressure Rating
The Graco SG3 Airless Spray Gun is rated for a maximum operating pressure of 3,600 PSI. This high-pressure specification indicates it is designed to work with professional-grade airless sprayers that deliver significant force. The Graco TrueCoat 360 Single Speed uses a stainless steel piston pump to handle pressure, but its key specs list it as single speed rather than a maximum PSI limit. The SG3 is built to withstand the higher forces found in industrial or heavy-duty setups. You need to match the gun to your machine's output to avoid damage.
Project Capacity
The Graco TrueCoat 360 Single Speed is explicitly designed for projects up to 2 gallons in size. This capacity makes it a complete system for medium-sized household tasks like painting a fence or a room. The Graco SG3 is a standalone gun accessory. It does not have an integrated tank or pump capacity listed in its specifications. It relies entirely on the connected sprayer for material supply. If you are looking for an all-in-one unit for a 2-gallon job, the TrueCoat 360 is the complete package. The SG3 requires you to already own a compatible sprayer.
Trigger Control
Control is a major difference between these two tools. The Graco SG3 features a full 4-finger trigger designed for a light, smooth pull. This ergonomic design provides you with precise control over the spray pattern and flow. The Graco TrueCoat 360 Single Speed does not list specific trigger mechanics in its published specs. It is marketed as a fast and easy alternative to brushes and rollers. For users who require fine motor control and comfort during long spraying sessions, the SG3's specialized trigger offers a distinct advantage in usability and precision.
Included Accessories
The Graco SG3 comes with a comprehensive set of components right out of the box. It includes a built-in hose swivel, a RAC IV 515 spray tip, a 50 mesh gun filter, and a RAC IV hand-tight guard. It also features a replaceable in-handle paint filter. The Graco TrueCoat 360 Single Speed includes an easy fill funnel and strainer system. It does not list specific spray tips or gun filters in its key specs. The SG3 provides more immediate hardware for setting up your spray pattern and protecting your equipment from debris.
Physical Dimensions
Size and weight matter for portability and storage. The Graco SG3 Airless Spray Gun is compact, measuring 8 inches in height and weighing just 1 pound. Its small footprint makes it easy to handle and store. The Graco TrueCoat 360 Single Speed is a larger unit, measuring 15 inches in length, 9.75 inches in height, and 5.25 inches in width. It is significantly bulkier due to its integrated pump and tank. If you need a lightweight accessory to attach to an existing machine, the SG3 is the more portable choice. The TrueCoat 360 is a stationary tool for specific projects.
