Printable PageSpray Tip InformationThe information provided in this section should help you understand why spray tips are so important, how to determine which tip is the best choice depending on the spray application at hand and your specific Graco or Magnum sprayer, and some general information on tip wear. Using the appropriate tip reduces overspray and provides more control. This means you can save money and complete your painting project faster when you use the right tip for the job.
Tip Size SelectionThe size of the tip is determined by three main factors:
Coating Determines Hole SizeYou can determine which spray tip orifice (hole) size to use by the thickness (viscosity) of the coating you will spray. Spray tips are labeled by their hole size in inches.

Spraying Surface Determines Fan SizeSmall surfaces (cabinets, fences, railings) require smaller fan widths for:
Match Your Sprayer To The Right TipThe key difference in sprayers is the maximum tip size they can support. Choose your sprayer based on the coating types you’ll be spraying.
Start with a tip one size smaller than the maximum tip size your sprayer supports. This allows for tip wear, which increases the tip hole size.
Understanding Tip Wear
It’s important to replace a tip when it gets worn to ensure a precise spray pattern, maximum productivity and quality finish. When a tip wears, the orifice size increases and the fan width decreases. This causes more paint to hit a smaller area, which wastes paint and slows productivity. Tip life varies by coating, so if a tip is worn, replace it. Extend tip life by spraying at the lowest pressure that breaks up the coating into a complete spray pattern (atomize). Do not increase the pump pressure; it only wastes paint and causes unnecessary pump component wear. Recommended Spray Tip Replacement Time: Does your tip need replacing?

Choosing the right spray tip is essential for ensuring a quality finish -- no matter which coating material is being sprayed. However, spray tips will wear with normal use.
