Harder & Steenbeck EVO 2024 0.45mm Fineline Aircap with Seal & Needle Cap for precise atomization

Precision fineline airflow: a dedicated 0.45mm EVO 2024 aircap with integrated seal and needle cap engineered for crisp, controlled sprays on compatible Harder & Steenbeck and partner airbrushes.

This replacement aircap delivers a finer, more consistent atomization for detail work, offering a snug seal and protective needle cap to reduce damage and leakage. Designed for artists and technicians who need predictable spray patterns from their EVO 2024-family and select Infinity/Ultra series airbrushes, this part is built to the brand's tolerances for fit and finish.

Will this aircap work on my airbrush model?

The 0.45mm fineline aircap is compatible with a range of Harder & Steenbeck and partner models, fitting both current and many earlier generations. It mounts directly to EVO 2024 bodies and several Evolution, Ultra, Infinity, and Kyiv Infinity variants without modification.

• Fits EVO 2024 and ULTRA 2024 models
• Compatible with Giraldez Infinity and Ultra series from 2006–2023
• Works with Evolution models from 1998–2023 and Infinity models from 2007–2023
• Also compatible with all Kyiv Infinity versions

How does the 0.45mm fineline aircap affect spray performance?

With a 0.45mm aperture the aircap narrows the airflow to produce a finer, more defined fan and tighter atomization than larger caps. That gives better control for lines, detail shading, and thin fills while maintaining a stable spray at moderate pressures.

• Tighter spray pattern for precise line work
• Improved atomization of thin paints and inks
• Stable performance at a range of working pressures

What benefits do the seal and needle cap provide?

The built-in seal helps prevent air or fluid leaks where the cap meets the nozzle, improving consistency and reducing maintenance. The included needle cap shields the needle point when the airbrush is stored or transported, lowering the risk of bending or contamination.

• Leak reduction for consistent air/paint flow
• Needle protection during storage and travel
• Minimizes need for frequent adjustments or repairs

How should I install and maintain this aircap?

Installation is straightforward: remove the old cap, clean mating surfaces, then hand-secure the new cap until it seats evenly. Routine cleaning and gentle handling of the needle cap will prolong service life and keep spray behavior predictable.

• Clean threads and nozzle seat before fitting
• Tighten by hand; avoid over-torquing
• Wipe with a soft cloth and appropriate cleaner after use

Who is this for: Artists, modelers, illustrators, and technicians who own EVO 2024 or compatible Evolution/Ultra/Infinity airbrushes and need a reliable 0.45mm fineline aircap with a sealing feature and needle protection. It’s ideal for users seeking greater line definition, reduced leaks, and a durable replacement part that preserves factory performance across multiple Harder & Steenbeck and partner models.
