When it comes to actual operation, we recommend that you stick to the manufacturer’s instructions and avoid undertaking repair if you are new to the Graco RAC series.
1. Working Principle
Fine finish, low-pressure tip works for airless paint sprayer by reducing the energy required to atomize the paint (fluid) before reaching the surface under paint application.
The FFLP tip utilizes the internal orifice design to blend the pressure difference (between entry and exit) and cause complete atomization needed for quality paint finish.
Moreover, the orifice diameter is a function of intended quality and fan width as per the spray area under paint application. Moreover, the low-pressure concept of FFLP makes it more common in airless spray paint applications.
2. Tip Performance
The FFLP tip delivers a quality finish by preventing surface overspray and enhancing the paint atomization process.
Unlike Low-pressure tips, FFLP tips are designed to eliminate surface drains and enhance quality finish performance during spray painting.
You will like the fine finish layer created by the FFLP, unlike other conventional tips that lack self-leveling surface properties and control dial.
As compared to low-pressure tips, FFLP comes with 50% efficiency and low energy gain from the power source.
You will spend far much lesser when using FFLP, than when you use RAC X gun tips.
Further, the quality of the paint finish is quite high, while the atomization process is 100% attained without any internal complications.
4. Cleaning Options
FFLP tips are simple and more comfortable to clean. Usually, the tip guard is nicely threaded into a universal tip fastener for motion stability.
When cleaning, you only need to unscrew the guard and pull the FFLP tip gently. Further, dip the tip in thinner to clean the orifice and paint channel.
You can opt to pass pressurized clean water to flush paint that may be stuck within the orifice.
5. Repair and Replacement
During paint application, the tip guard is often affected or damaged due to excessive vibrations or surface collisions.
The FFLP tip may fail to atomize paint solvent completely – this affects the finish coat quality. In such a condition, you’ll have to clean the tip to remove the internal clog and pre-test it (for assessment).
Alternatively, the FFLP tip can be replaced with a new one, (of the same type and size) to restore your Graco paint sprayer to its original performance.
6. FFLP Tip Sizes and Tip Design
Fine finish, low-pressure tips are designed and manufactured in various sizes to meet prevailing painting needs.
Though the working principle and overall design may be the same, the orifice size and interior channel differ as per the area extent and paint type you intend to handle using a particular FFLP tip.
In order to identify the best FFLP tip size for your paint application process, you need to know the diameter of the orifice, which defines the spray fan width.
To do this, check the FFLP tip number, i.e. FFLP 310. If the first digit is doubled, then you’ll get the width of the spray fan-generated when painting. In this case, FFLP 310 tip will produce a 6-inch diameter patch when spraying.
Before making your purchase decision, consider the surface area you need to spray paint and undertake fan width calculations (as explained above), to prevent overspray.
Moreover, note the maximum pressure (PSI) under which every FFLP tip operates.

7. Spray Action – overspray
The FFLP (green) is specially designed to eliminate overspray problems during paint application.
The available FFLP tip sizes allow optional selection to match your spray width and eliminated drains or surface run.
The quality of paint finish is best achieved by using FFLP tips (green) instead of conventional pray tips when using an airless sprayer.
8. Compatible Paint Use
FFLP tips handle well-thinned paint to prevent blocking and internal clogging.
You can use FFLP with latex paint, enamel, acrylic, or satin paint comfortably without experiencing any failure.
However, for an airless paint sprayer, the fluid pressure (PSI) should not exceed 3500 for safety purposes.
Many painters tend to use guard, though that won’t necessarily guarantee you safety when it comes to pressure inbuilt effects.
High viscous paint should not be used with FFLP as it blocks the channel and destroys the quality of the finish layer.

9. Area of Use
The FFLP tips (green) size 110 and 108 are best suited for spraying cabinets and frames and spindles. The narrow output design minimizes over sprayer and attains classic finish without blowing out.
For shelves and cabinet doors, consider FFLP 210 (green) – the tip works excellently with latex paint and overcomes internal clogging in case of pressure built up.
Doors and trims can be handled by either, FFLP 310 tip (green), or FFLP 311 tip (blue). The tips produce a 6-inch fan width that covers the surface nicely during application.
Depending on the thickness of the paint solvent, you may consider having a wider orifice tip like FFLP 312 or FFLP 313.
Wall, ceiling, fence, and exterior siding requires an FFLP 516 or FFLP 517 tip that can handle wide a wide range of acrylic paint without getting fatigued. A newly constructed wall needs FFLP 615 or FFLP 721 to contend with high volume flow demands.

What are the Key Features of FFLP Tips?
To understand the FFLP tip in-depth, it’s important to know its key features and functionality without overlooking the associated advantages. These include:
- Reduced overspray and net pressure by up to 50%
- It’s more comfortable to clean and replace
- FFLP Utilizes Smart Tip Technology to attain the fine quality finish
- Does not experience pressure fluctuation during spray action
- Works with urethane, acrylics, latex, stains, lacquers, and varnishes without blockage
- The RAC technology integrated eliminates internal channel clogging
- The universal tip color is green – easier to identify
- FFLP guarantees the double time’s service life
- Manufactured in a variety of orifice sizes – optional selection
- Reduces atomization energy by half
- Fits nicely with standard universal guards
Remember, the cost of each particular size of the FFLP tip may vary according to the material used, the size, and the design complexity.
