3M Accuspray Atomizing Head replacement for HG09, Clear 1.8 mm 4-Pack — medium-fine atomization, quick-swap

The 3M Accuspray Atomizing Head 16611 is a clear, 1.8 mm replacement atomizing head set (4-pack) designed to restore spray performance on the 3M Accuspray HG09 gun for a wide range of coating viscosities.

When working with primers, sealers, basecoats or clear coats, worn atomizing heads reduce transfer efficiency and spray quality. These replaceable heads let technicians swap fresh atomizers quickly to maintain even fan patterns and consistent droplet size without buying a new gun. The transparent construction also helps you confirm cleanliness before use and supports compatibility with 3M Accuspray ONE and PPS systems.

How does the 1.8 mm atomizing head affect spray results?

The 1.8 mm orifice is sized to produce a medium-to-fine atomization ideal for many automotive and industrial coatings. It balances flow rate and droplet size to give reliable coverage while minimizing over-spray when matched to the correct pressure and technique.

• 1.8 mm opening for medium-fine atomization
• Helps deliver consistent fan pattern across passes
• Works well with primers, basecoats, sealers and clears
• Compatible with typical shop air pressures and settings

How easy is it to replace and maintain these heads?

Replacement is fast and tool-free on the Accuspray HG09 gun, letting you return to production with minimal downtime. The see-through material makes rinsing and inspection simple, so you can confirm residual material is removed before the next use.

• Quick swap design for fast head changeout
• Transparent body allows visual cleanliness checks
• Simple rinse procedures reduce curing or clog risk
• Keeping spare heads on hand restores 'like-new' performance

Will these heads work with my existing 3M systems?

Yes — the 16611 atomizing heads are engineered for the 3M Accuspray Spray Gun Model HG09 and integrate with both the Accuspray ONE and PPS fluid delivery systems. They are intended for industrial and occupational use where consistent spray results are required.

• Designed for 3M Accuspray HG09 spray gun
• Compatible with 3M Accuspray ONE and PPS setups
• Suitable for a range of coating viscosities from low to high
• Sold as a 4-pack to maintain workflow continuity

Who this is for: Professionals and industrial painters who rely on the 3M Accuspray platform and need fast, dependable atomization across primers, sealers, base and clear coats. If you operate a collision, refinishing, or production spray environment and require minimal downtime plus repeatable finish quality, this 4-pack of clear 1.8 mm heads helps keep the gun performing like new between maintenance cycles.
