An airless paint sprayer is a tool familiar to many men. But many people do not know about the structure of the device and find it difficult to deal with problems occurring. So, what are Graco paint sprayer parts and how do they work? Read through the article to find out the answer.
List of Graco Paint Sprayer parts
Pump (Fluid Section)
The first part of a Graco paint sprayer is the pump (also called the fluid section) which is considered the heart of an airless paint sprayer because it is the most important part. It works by pumping paint at very high pressure, through a hose and out a tiny hole in the spray gun tip.
There are two pump types, piston pump, and diaphragm pump. Both work very well. But the diaphragm type won’t be able to pump the very thick liquid as a piston pump can.
- Graco pumps help the industry in durability and ease of installation. So, If you keep a spare on hand, you can reduce downtime on the job when repairs need to be made. With just a few simple steps, you can take out the pump on a small or midsize electric sprayer. So, you don’t have to waste time and money on charges at a repair facility.
- Some Graco Endurance Pumps are equipped with additional features, such as the Chromex Rod, to extend its wear. Indeed, the extremely hard Chromex rod and stainless steel sleeve deliver better performance by resisting abrasion from the material.
- The pump is made of stainless steel or aluminum, allowing it to handle a variety of fluids.
- This part helps save material and time during flushing, priming, refilling materials, and color changes.
This is an ideal add-on that helps extend your reach and eliminate the hassle of using a ladder to safely spray high walls, vaulted ceilings, eaves, decks, railings, soffit, and other areas that are out of your reach.
The hose is designed to deliver a steady stream of high-pressure fluid to the spray gun. Graco hoses are durable, flexible, and designed to ensure you get the best results from your airless sprayer.
When you need to replace the hose, you should check the maximum hose length that your sprayer supports.
- The lightweight increases hose flexibility and improves usability while spraying under pressure.
- The conductive core is designed based on the highest worldwide safety standards, unlike competitive ground wire hose designs.
- The plated spring guards have high corrosion resistance.
Containers and liners
The cup is used to contain the paint. The liner and container keep the paint fresh, flowing properly to the sprayer. They also make the cleaning process simple and easy. Just toss or reuse it after you finish spraying.
The liner and container system also allows you to spray in any direction, even upside down. You could buy an extra container to make it easy for switching between colors or materials.
- Graco cups have a large material capacity which helps save time and reduce the number of refills, hence, to finish bigger jobs faster.
- Easy for installation and clean-up.
- Includes a cover for storage.
Graco Suction Tube is designed to be used with Magnum airless paint sprayers. It connects to the bottom of the paint sprayer via a threaded fitting and has an inlet strainer that connects to the other end. With high flexibility, the suction tube handles different materials.
- Replacing a worn suction tube to avoid leaks, potential cracks, and clogs that reduces sprayer pressure.
- The tube should also be replaced when it is brittle and accumulated with paint to maintain high performance.
Another important component of a Graco paint sprayer is the gun which is an on/off valve for the material being sprayed. This is the last stop for the fluid before being applied and is a key item that decides the quality of the final finish.
When we pull the trigger, the valve is opened and paint is allowed to go to the tip and finally to the surface being painted. Graco spray guns provide a comfortable spraying experience for all of your projects because it is well-balanced and lightweight.
Choosing the right spray gun is important because it decides the comfort of the spray experience.
Normally, Graco has 2 and 4 finger airless spray guns. The numbers, 2 or 4, refers to the number of fingers needed to pull the trigger.
- Lightest trigger pull and hold force at all spray pressures and reduces operator fatigue
- Easy one-finger, ambidextrous trigger lock
- Durable forged aluminum or stainless steel withstands harsh work environments
- Help shut up faster and reduce spitting of light viscosity material
- Filters from the inside out to prevent the filter from collapsing
The tip is designed to break up the material evenly into tiny droplets. By choosing different tips, you can spray thin materials like stain, lacquer, and varnish or thicker liquids like latex house paint.
It is important to choose the right tip because it determines the quality of the final finish and helps save you time and money.
- The tip geometry reduces the energy required to atomize your favorite paints, stains, and other materials – delivering a superior finish with less pressure
- Graco tip delivers a soft spray pattern. So, it’s easier to deliver a professional quality finish. It also helps control the device more easily and reduce overspray on different surfaces with a wide range of coatings, from stains to exterior paints.
- Graco tip provides better control to easily blend each spray pass for a superior finish.
- Intuitive design provides quick identification of spray direction.
- Easily installs on spray guns without removing the tip guard and housing.
Spray tip guard
The tip guard helps to reduce paint build-ups, dripping, and spitting. It also helps provide safety when spraying at higher pressure. The design makes it easy to attach or remove without complicated tools.
- Reliably seals when tightened by hand (no leaks)
- Aluminum nut won’t rust or corrode
- No tools required for installation

Cleanshot shut-off valve
This is a unique needle valve that shuts fluid off at the tip for a clean pattern, causing no spitting. It is a great addition to any extension.
- 180-degree tip swivel provides versatility when spraying high surfaces such as walls and ceilings.
- The valve allows fluid to flow off for a clean pattern without spitting.
Gun filters and Strainers
The gun filter made from high-quality stainless steel helps reduce tip plugging and provides a higher quality finish by filtering out unwanted particles from the paint material. So, it’s essential when spraying low-quality paint.
You should thoroughly clean the fun filter after each use to increase filter life.
There are two main types of gun filters.
100 mesh filter: designed to be used for thinner material such as stain and lacquer.
60 mesh filter: designed to be used for materials such as primer and latex paint.
The tip guard filter provides additional filtering when using a tip that is flat to help reduce paint build-up and provide a higher quality finish. The tip filter is placed inside of the tip guard on the Graco airless spray guns.
- Prevents dirt and debris from entering the spray pattern
- Help to have better paint atomization, minimize overspray, and helps to provide better material coverage
- It is placed directly into the guard and filters paint for fewer tip plugs
Manifold filter (Mesh Screen)
A mesh screen, also called a manifold filter, is designed to catch debris that may have entered your sprayer. Your airless spray gun can be damaged and may your hose be punctured when there is no manifold filter.
There are 2 main types of a mesh screen.
The 100 mesh filter is designed to be used with lacquers, enamels, and solvent-based paints.
The 60 mesh filter is designed to be used with thicker liquids such as Latex and Enamels.
- Protects pump from harmful particles
- Extends the life of your paint sprayer
- Helps maintain consistent spraying pressure
This is to keep the manifold filter in place to filter the paint before it travels into the hose.
Pump filter (Handheld Filter)
Like other filters, this filter also improves the quality of the final finish by removing unwanted debris from the paint before being sanctioned to the pump.
The 100 mesh filter is designed to be used with thinner material such as stain and lacquer. It’s compatible with Ultra, Ultimate, and TC Pro Handheld models.
The 60 mesh filter is designed to be used with thicker material such as primer and latex paint. It’s suitable to be used with Ultra, TC Pro Handheld models, and Ultimate.
This component helps prevent unwanted particles from being suctioned into the pump and reduces tip clogging, causing damage to the sprayer. Hence, it helps eliminate surface blemishes and plugged tips.
The inlet strainer should be cleaned and replaced regularly to extend the pump life and give a superior finish.
