3M Accuspray Atomizing Heads 2.0 mm Red — 4-Pack for High-Viscosity Coatings, Quick-Change Clear-Tint Tips

3M Accuspray 16609 atomizing heads are replaceable, clear-tinted spray tips (2.0 mm, red) made for rapid, controlled application of higher-viscosity coatings with Accuspray ONE and HGP systems.

These 2.0 mm red atomizing heads are part of 3M’s modular Accuspray system designed to let technicians swap nozzle heads quickly to match material viscosity without changing the whole gun. Molded from transparent plastic with a colored tint for fast size identification, each head delivers repeatable atomization for heavy-bodied primers, adhesives, undercoatings and specialty coatings while cutting downtime for cleaning and maintenance.

How does the 2.0 mm head perform with thick materials?

The 2.0 mm size is engineered to move higher-viscosity fluids reliably, producing coarse-to-medium atomization that reduces clogging and supports high-volume delivery. It is commonly used with Accuspray HGP guns for gel coats, heavy primers and sound-dampening compounds.

• Optimized bore size for thicker primers and adhesives
• Stable spray fan at higher flow rates to maintain coverage
• Compatible with high-volume supply systems to minimize reloading

Can I clean and reuse these atomizing heads?

Yes — the heads are made from clear plastic so technicians can see residue and determine when cleaning is complete, which shortens turnaround time during busy jobs. They are also inexpensive and simple to swap if replacement is faster than cleaning.

• See-through construction for quick visual inspection
• Design allows for solvent or mechanical cleaning depending on material
• Quick-release fit for fast changeover between jobs

Will these heads work with all Accuspray guns and coatings?

These 2.0 mm heads are designed specifically for the Accuspray system and are best suited to Accuspray ONE spray guns and the HGP high-volume pistol. While many coating types are supported, choose head sizes to match material viscosity for best finish quality.

• Intended for Accuspray ONE and Accuspray HGP systems
• Recommended for high-viscosity coats like undercoats and adhesives
• Use other sizes (1.2–1.8 mm) for low-to-medium viscosity where fine atomization is required

How does swapping heads benefit workshop workflow?

Changing atomizing heads provides the spray characteristics of a different gun without swapping entire hardware, saving cost and setup time. That flexibility helps techs respond quickly to varying job requirements and reduces downtime during color or material changes.

• Delivers new-gun performance by replacing only the head
• Reduces the need for multiple dedicated spray guns
• Color-coded heads speed identification and minimize mistakes

Who is this for: The 3M Accuspray 16609 2.0 mm red atomizing head (4-pack) is aimed at collision-repair shops, marine and aerospace refinishers, and industrial painters who apply high-build primers, gel coats or adhesives and need reliable, high-volume atomization with quick turnaround. It suits technicians who prefer modular systems over maintaining multiple complete spray guns and who require visible, easy-to-clean components to optimize shop productivity.

Features include replaceable sizes for low- to high-viscosity coatings, see-through heads for faster cleaning checks, quick replacement for instant new-gun performance, and compatibility with 3M Accuspray ONE and PPS systems. For occupational and industrial use only.
