3M Performance Gravity HVLP Atomizing Head Refill Kit 1.8mm — Restores Spray Pattern & Faster Cleanup

The 3M Performance Gravity HVLP Atomizing Head Refill Kit (26718) is a 1.8 mm quick-change gravity-feed nozzle set that restores premium spray pattern, atomization and transfer efficiency for the 3M Performance Spray Gun System.

This refill kit includes a replaceable atomizing head sized for high-build primers, primer surfacers and heavy-bodied coatings, and is designed exclusively for use with the 3M Performance Spray Gun and the 3M PPS Series 2.0 gravity cup system. Because the fluid only passes through the disposable atomizing tip—not the spray gun body—you can maintain consistent, like-new spray characteristics by swapping nozzles instead of performing frequent teardown and deep cleaning.

How does replacing the atomizing head improve spray consistency?

Changing the atomizing head renews the critical fluid path and tip geometry, so pattern shape and droplet breakup remain stable job after job. This reduces variability caused by wear or dried material inside the nozzle, delivering repeatable results across large panels or multiple cars.

• Restores original spray pattern and fan width
• Minimizes sagging or orange-peel from worn tips
• Faster turnaround between color or material changes

What coatings and applications is the 1.8 mm nozzle best for?

The 1.8 mm atomizing head is calibrated for thicker products where higher flow and coarser atomization are needed—common in high-build primers, surfacers and sprayable fillers. It works with solvent and waterborne systems when used within the recommended pressure and thinner guidelines.

• High-build primers and primer surfacers
• Sprayable fillers and high-viscosity coatings
• Sealers and heavier single-stage top coats when specified

How does this nozzle speed up cleanup compared to traditional guns?

Because paint only contacts the disposable atomizing head and the PPS Series 2.0 cup, you avoid sending coatings through the spray gun body. That reduces the need for complete gun disassembly and long solvent soaks—often cleanup can be limited to exchanging the nozzle or a simple tip rinse.

• Less time spent disassembling and soaking gun components
• Lower solvent use and reduced material waste
• Faster color changes with less cross-contamination risk

How do I install or remove the atomizing head?

Installation is tool-free: the atomizing head seats onto the spray gun needle and is locked in place by the specially engineered collar. Removal is equally quick—unlock the collar, lift off the head, and either clean the fluid tip appropriately or install a fresh replacement to resume optimal performance.

• Tool-free changeouts using the locking collar
• Attach directly to 3M Performance Spray Gun needle and whip hose fittings
• Compatible exclusively with gravity-feed 3M PPS Series 2.0

Who is this for: The 3M Performance Gravity HVLP Atomizing Head Refill Kit 26718 is aimed at professional autobody shops, industrial coatings specialists and refinish technicians who demand consistent, high-quality finishes and faster shop throughput. If you use the 3M Performance Spray Gun and the PPS Series 2.0 system and need reliable nozzle performance for high-build primers and thicker materials, this 1.8 mm refill provides a practical way to maintain peak spray characteristics with minimal downtime and cleanup.

Key specifications and reminders: 1.8 mm nozzle size; designed for gravity-feed 3M PPS Series 2.0; use within manufacturer-recommended pressures and materials; intended for industrial/occupational use only.
