Description
Graco Flex Plus Airless Spray Gun 2 Finger Trigger RAC 5 LineLazer
When striping paint is thick and production matters, the Graco Flex Plus Airless Spray Gun delivers the flow, durability, and control professionals expect. Designed specifically for striping applications and heavy materials, this gun maximizes output while minimizing downtime on the job.
With a two-finger trigger and RAC 5 LineLazer SwitchTip and Guard, the Flex Plus is engineered for comfort during long striping runs and consistent spray patterns at high pressures. The direct hose connection bypasses the handle, allowing heavier coatings to move freely—like opening up a wider funnel so nothing backs up.
Key Benefits:
Maximized material flow for striping paints and heavy coatings
Two-finger trigger reduces hand fatigue on long line runs
Large internal fluid path helps reduce tip clogging
Patented needle design increases service life and reliability
Spring guard adds hose support and jobsite durability
How to Use the Graco Flex Plus Airless Spray Gun
Verify compatibility with your airless sprayer or LineLazer unit.
Connect the airless hose directly to the gun inlet (1/4 in NPSM).
Install the included RAC 5 LineLazer SwitchTip and guard.
Ensure trigger lock is engaged before pressurizing the system.
Pressurize the sprayer and test spray on cardboard or pavement scrap.
Adjust striping speed and gun height for consistent line width.
Flush the gun thoroughly after use, especially when spraying heavy materials.
The no-adjustment needle design allows for quick repairs and fewer tuning steps in the field, keeping crews productive.

FAQ
What makes this spray gun better for striping than standard airless guns?
The Flex Plus is designed for high flow and heavy coatings. The direct hose connection and large fluid path reduce restriction, which is critical when spraying striping paint or thicker materials.
Is the two-finger trigger worth it?
Yes. On long striping jobs, a two-finger trigger distributes pull force across the hand, similar to using two hands to lift a heavy bucket instead of one. This reduces fatigue and improves control.
Does this gun clog less with thick paint?
The large internal fluid path and patented needle design help reduce clogging compared to smaller, more restrictive guns, especially when materials are properly filtered and mixed.
Can this be used outside of line striping?
Yes. While optimized for striping, it also performs well with heavy coatings and joint compounds in airless spray applications.
Differentiation & Value
Compared to lighter-duty airless spray guns, the Flex Plus is purpose-built for demanding striping work. It offers higher flow capacity, fewer adjustments, and longer service life—making it a strong upgrade over generic airless guns and a dependable choice for professionals who rely on clean lines and consistent output.
When striping quality affects safety, appearance, and rework costs, having the right spray gun makes all the difference.
