3M Performance Gravity HVLP Atomizing Head Refill Kit 26718 — 1.8 mm for High-Build Primers, Quick-Change

3M Performance Gravity HVLP Atomizing Head Refill Kit 26718 is a replaceable 1.8 mm atomizing head designed to restore like-new spray performance in 3M gravity-feed spray guns.

Designed for the 3M Performance Spray Gun System and the 3M PPS Series 2.0 gravity cup, this refill atomizing head delivers reliable pattern control and efficient atomization for higher-viscosity primers, surfacers and fillers. Because coatings travel only through the disposable atomizing head rather than the gun body, routine maintenance is faster and contamination risk is lower. The 1.8 mm size is tuned for high-build and thicker materials, helping professional refinishers and industrial painters maintain consistent results across jobs.

What improvement will this 1.8 mm atomizing head make to my spray pattern?

The 1.8 mm atomizing head is calibrated to produce a heavier, consistent fan and droplet size suited to high-build primers and viscous coatings. It improves transfer efficiency for thicker materials while maintaining controllable edge definition and overlap.

• Optimized fan for high-build primers and surfacers
• Consistent droplet size to reduce runs and orange peel
• Improves material transfer with thicker coatings
• Quick-change nozzle ensures steady performance with each swap

How does the replaceable atomizing head reduce cleanup and downtime?

Because paint only passes through the disposable atomizing head, you can remove and replace the fluid tip instead of disassembling and soaking the entire spray gun. That lowers solvent use and minimizes shop downtime for cleaning, returning the gun to service faster.

• Replace nozzle instead of full gun teardown
• Compatible with PPS Series 2.0 for reduced cup contamination
• Less solvent waste and faster changeouts
• No extra tools required—locking collar secures the head

Which coatings are best matched to the 1.8 mm 26718 atomizing head?

The 1.8 mm atomizing head is intended for thicker, high-build materials where a larger fluid orifice improves flow and coverage. Typical uses include high-build primers, sprayable fillers, primer surfacers and other higher-viscosity solvent or waterborne formulations.

• High-build primers and primer surfacers
• Sprayable fillers and sealers
• Thicker single-stage and basecoat materials when specified
• Works with both solvent-based and waterborne coatings when recommended

How do I install and secure the 3M atomizing head?

Installation is tool-free: remove the existing fluid tip, fit the atomizing head onto the spray gun needle, then tighten the specially designed locking collar. The secure connection keeps the head aligned and sealed for stable spray performance.

• Slide atomizing head onto the spray gun needle
• Hand-tighten the locking collar—no extra tools needed
• Confirm fit to prevent leakage and maintain pattern control
• Replace or clean the tip between jobs as appropriate

Who is this for: The 3M Performance Gravity HVLP Atomizing Head Refill Kit 26718 (1.8 mm) is intended for professional refinish shops, industrial coating applicators and fleet maintenance teams using the 3M Performance Spray Gun System and PPS Series 2.0. If you routinely spray high-build primers, fillers or other viscous coatings and need dependable, quick-change nozzles that lower cleanup time and help maintain consistent spray results, this atomizing head is built for your workflow.
