Frequently Asked Questions
If your unit is an airless sprayer with a standard 1/4" hose connection and pressure capacity up to 3600 psi, the 17Y042 will typically work. See the Compatible Machines list above and match your hose thread, pressure rating, and RAC X tip size to your sprayer’s output.
A 517 tip (0.017" orifice, ~10" fan at 12") suits many architectural latex paints and primers. Heavier or lighter materials may require different RAC X tip sizes—always select a tip that your sprayer can support and that matches the coating manufacturer’s guidance.
The Contractor PC features reduced trigger force, an adjustable trigger length, and a ProConnect™ Cartridge so you can replace internal wear parts quickly on the job—cutting downtime and maintenance complexity.
Use a 1/4" airless hose rated for at least 3600 psi, and match the gun filter mesh (e.g., 60–100 mesh for most latex) to your coating and tip size to minimize clogs and improve finish quality.
