Part number 0143409 is an AirCoat Nozzle with a size designation of 9/40. This specialized fluid tip is engineered for the SprayTech AirCoat GM 2600 air-assisted airless spray system, designed specifically for high-output application of heavy-viscosity materials. The 9/40 configuration produces a focused 9-inch fan pattern while utilizing a substantial 0.040-inch orifice diameter, creating the highest flow capacity available in the 9-inch fan width category.
This nozzle size is optimized for demanding industrial applications requiring rapid material deposition with thick coatings. The 0.040-inch orifice provides exceptional flow capacity for highly viscous materials such as heavy-bodied protective coatings, high-build epoxies, corrosion-resistant urethanes, mastics, sound deadeners, and textured finishes. Despite the high flow rate, the AirCoat technology maintains superior atomization quality at lower fluid pressures than conventional airless systems, producing a more controllable spray pattern with reduced overspray and bounce-back.
The 9/40 nozzle represents the high-flow extreme of the 9-inch fan width family. This relatively narrow fan width concentrates the substantial material output into a manageable pattern, making it ideal for production environments where operators are applying heavy coatings to defined areas such as structural steel, tank interiors, marine surfaces, and industrial equipment. The narrower fan allows for precise control while the high flow rate enables rapid film build in a single pass.
Nozzles of this size are subjected to extreme wear due to the high-velocity flow of abrasive pigmented materials through the precision orifice. The carbide insert is engineered for maximum durability, but eventually, the orifice will erode, becoming enlarged and out-of-round. This wear manifests as pattern distortion, tails, increased material consumption, and degraded finish quality. Regular pattern testing and timely nozzle replacement are essential for maintaining application efficiency and achieving consistent, professional results with high-viscosity materials.
| High-Volume Flow Control | 0.040-inch orifice delivers maximum material output for heavy coatings |
|---|---|
| Focused Fan Pattern | 9-inch fan concentrates high flow rate into a manageable, controlled pattern |
| Viscous Material Atomization | Precision geometry enables fine atomization of heavy-bodied materials at lower pressures |
| Pattern Defects | Spray fan has tails, is split, heavy on ends, or shows distorted shape |
|---|---|
| Orifice Wear | Orifice appears oval, enlarged, or has visible nicks under magnification |
| Excessive Material Usage | Higher than normal consumption indicates orifice enlargement beyond tolerance |
| Finish Quality Decline | Orange peel, streaking, or rough texture despite correct pressure and material parameters |
Part number 0143409 is specifically designed for the SprayTech AirCoat GM 2600 air-assisted airless spray gun. This high-capacity nozzle is part of the comprehensive AirCoat nozzle range for this system, allowing users to select the optimal combination of fan width and orifice size for their specific high-viscosity application requirements. Always confirm fitment using the correct parts diagram for your exact model.

The high-flow 9/40 nozzle requires proper support from the entire fluid delivery system. These related components are often inspected or upgraded when utilizing this large orifice size.
High-flow nozzles require adequate atomization and shaping air volume. The air cap must be clean and undamaged to properly handle the increased material flow.
A clean, properly sized gun filter is essential to prevent debris from reaching and damaging the large precision orifice.
The needle must seal perfectly against the nozzle seat. High-flow applications magnify the effects of any wear or damage to these sealing surfaces.
