Applications for Spray Gun Needles, Nozzles and Air Cap Sets
Spray gun needles and nozzles help regulate material delivery and maintain consistent spray patterns across coating and finishing processes. These parts are commonly used in automotive refinishing, industrial coating, woodworking, maintenance and other controlled spray-finishing applications. When correctly matched to the spray gun, air cap and coating material, they support proper atomization, stable pattern width and finish quality across materials with different coating viscosities. If you need a complete gun rather than a replacement part, Selectum also carries spray guns in a separate category.

How to Choose the Right Needle or Nozzle
Choosing the right needle or nozzle starts with confirming fitment for your spray gun model and coating material. The listed needles, nozzles and air cap sets are manufacturer-specific replacement parts intended for specific spray gun models according to the manufacturer's specifications. When selecting a part, confirm the spray gun model, manufacturer part number, nozzle or fluid tip size, matching needle or air cap, coating material, coating viscosity and desired spray pattern. Note that some parts ship individually while others are supplied as matched needle/nozzle or needle/nozzle/air cap assemblies, so check the listing before ordering. This category includes hundreds of listed options across multiple brands, so filtering by brand, part number and product type is the safest way to narrow the selection.
Complete your setup
Consistent spray performance also depends on clean, regulated air, so pair the correct needle or nozzle with compatible air caps, cups, hoses and air system components such as filters, regulators and lubricators.

Frequently Asked Questions
How do I choose the right spray gun nozzle?
To choose the right spray gun nozzle, start with the spray gun model and manufacturer part number, then confirm the nozzle size, matching needle, air cap compatibility, coating material and desired spray pattern. Many replacement parts are model-specific, so a 1.3 mm, 1.5 mm or 1.8 mm nozzle should not be selected by size alone unless it is confirmed for your exact spray gun.
Should I replace the needle and nozzle together?
In many spray gun setups, the needle and nozzle work as a matched pair. If one part is worn, damaged or causing an uneven spray pattern, replacing the needle and nozzle together can help restore consistent fluid flow and atomization. Always check the product listing or manufacturer part number to confirm whether the item is sold as an individual component or as a needle/nozzle set.
What is the difference between a needle, nozzle and air cap?
The needle controls fluid flow, the nozzle shapes the fluid opening, and the air cap helps atomize the material and form the spray pattern. Some products in this category are individual needles or nozzles, while others are needle/nozzle/air cap sets designed for a specific spray gun series such as the Pro-Tek 3000 HVLP or Anest Iwata WS-400.
Can I use this category to find airbrush needles and nozzles?
This category focuses mainly on spray gun needles, nozzles, air caps and related replacement parts. If you are looking for an airbrush needle or airbrush needles and nozzles, confirm the exact airbrush model, part number and needle/nozzle size before ordering, because airbrush parts are usually not interchangeable between models.
