Apollo HVLP guns are incredibly versatile. But the standard 1.0mm tip is a compromise- it works fairly well with most materials. To really let your Apollo show its stuff, size the needle to the material! After all, doesn’t it make sense that thicker materials should spray better through a large diameter tip? The standard "Thick/Thin" kit includes a Type "B" air cap, a .75mm tip and needle set for thin liquids like lacquer, and a 2.0mm needle set for liquids like latex paint. Ideally suited for use with the Apollo 3-Stage Heavy-Duty Turbine System APS-0800Q (Apollo model 825)and the previous model Spray Guns (Sold Separately). Ships in Apollo plastic case. Made in the USA.
