Blue rear casing for Gaahleri Mobius SP

Official Gaahleri Replacement to Keep Your Mobius SP Performing at Its Best

The rear housing is one of the most functional parts of the Gaahleri Mobius SP airbrush. When it wears out or gets damaged, control over the needle is directly affected, along with the quality of each paint pass. Having the original replacement is the quickest way to restore the airbrush to its factory condition without compromising any adjustments.

Cutaway Design: Immediate Access to the Mechanism

This housing incorporates a cutaway side that exposes the needle holder area. Thanks to this opening, it is possible to loosen or tighten the needle nut in seconds, without the need to completely disassemble the airbrush. In long painting sessions with frequent colour changes —common in static model decoration, figures, or dioramas— this detail makes a real difference in workflow efficiency.

Integrated Travel Limiter Knob

At the rear end, the piece includes a regulation knob that acts as a mechanical stop for the trigger. By turning it, the maximum needle pullback is limited, allowing for systematic repetition of the same line width without recalibrating between passes. It is especially useful when working in fine detail areas or when layering multiple coats on the same surface, requiring consistency in flow.

Blue Finish and Guaranteed Compatibility

The metallic blue finish identifies this housing as an original component of the Mobius SP and is not merely aesthetic: the thread and tolerances are manufactured to fit precisely into the main body of the airbrush. A generic replacement may introduce play that affects sealing or trigger behaviour; with the original Gaahleri part, those risks disappear.

Frequently Asked Questions

Is this rear housing compatible with other Gaahleri models?

It is specifically designed for the Gaahleri Mobius SP. We cannot confirm compatibility with other models from the brand without prior verification, as threads and tolerances may vary between references.

What real advantage does the cutaway design offer over a closed housing?

The side cut allows access to the needle holder nut without disassembling the airbrush. This speeds up cleaning and needle changes, which is highly valued when working with multiple colours in a single session.

Does the limiter knob allow for intermediate adjustments or only fixed positions?

The knob acts as a continuous travel stop: it can be turned to the desired point and remains fixed in that position, without predefined steps. This provides total freedom to calibrate the flow according to the technique used.

Is any special tool required to install this housing?

In general, assembly is done by hand using the thread of the main body. If you have questions about the process, consult the Mobius SP manual or contact our team before intervening with the airbrush.

Can the blue colour of the housing vary from the images?

The photographs reproduce the actual finish of the piece as faithfully as possible, but the nuances may vary slightly depending on the screen or lighting conditions. This is the official factory finish for this reference.
