Gaahleri 0.38mm Nozzle for GHAD-68 & CS-36 (Advanced Series)

Drop-in, self-centring 0.38 mm replacement nozzle with Gaahleri's 8 Micro-Air-Channel design. The fix for a split, bent or blocked nozzle on a GHAD-68 or CS-36.

The nozzle is where paint meets air, and its tip is the most delicate part of any airbrush. A hairline split or a tiny dent from a dropped brush or a pushed-through needle is enough to ruin the spray pattern, even if you can't see the damage with the naked eye.

Self-centring drop-in design. This nozzle doesn't screw into the body. It drops into its seat and is held and centred by the nozzle cap. No nozzle wrench, no risk of cracking it by overtightening threads, and it comes out for cleaning in seconds.

8 Micro-Air-Channel (MAC) design. Gaahleri's multi-channel airflow around the tip, intended to give even atomisation and a consistent pattern. This is the same nozzle type your GHAD-68 or CS-36 shipped with.

✔ Spray pattern pulls to one side or comes out as a comet shape instead of a round dot.

✔ Persistent spitting even with well-thinned paint, correct pressure and a clean airbrush.

✔ Paint bubbles back into the cup while spraying. Air is getting past a damaged or badly seated nozzle.

✔ A visible split, flare or dent on the tip under a magnifier or phone macro.

✔ Dried paint that won't come out after soaking and gentle cleaning.

✔ 1 × Gaahleri 0.38 mm nozzle for GHAD-68 / CS-36

Needle and nozzle cap are not included. They are separate parts (see below).

✔ Fits: Gaahleri Advanced Series GHAD-68 and Gaahleri CS-36, in their 0.38 mm configuration.

✘ Does not fit:

✘ GHAD-39: it runs a 0.35 mm setup with its own nozzle. Don't mix 0.35 and 0.38 parts.

✘ Swallowtail: it shares the GHAD-68's air valve but has its own finer nozzle setup.

✘ Seeker, Mobius, Aventus and other brands: different nozzle systems.

✘ Not for the 0.5 mm setup on your GHAD-68. If you're repairing the 0.5 mm side, you need the 0.5 mm nozzle.

✎ Needle, nozzle and cap work as a matched set. Always run a 0.38 mm nozzle with the 0.38 mm needle and 0.38 mm nozzle cap for GHAD-68/CS-36. A mismatched needle either won't seal (constant paint leak) or will jam into the tip and split it. We stock the matching 0.38 mm needle and nozzle cap.

1. Pull the needle back before you touch the nozzle. Loosen the needle chuck and draw the needle back several millimetres first. Most split nozzles are caused by the needle, not by cleaning.

2. Seat it, then cap it: hand-tight only. Drop the nozzle into its seat, then fit the nozzle cap snugly by hand. The cap centres and seals the nozzle. Extra force only deforms the tip.

3. Slide the needle forward last, and gently. Stop as soon as you feel it touch. The needle seals by resting in the tip, not by being pushed into it.

4. Test with water or thinner before paint. Check for a round, even pattern and no bubbles in the cup.

5. Clean from the back, never ream the tip. Soak in airbrush cleaner and use a soft nozzle brush. Pushing a reamer, pin or brush hard through the front is the fastest way to split a new nozzle.

6. Keep a spare. Nozzles are cheap and small. A spare in the drawer means a split tip doesn't stop a project mid-coat.

A new nozzle won't fix a bent needle. If your needle tip is hooked or bent (roll it on a flat surface and look at the point), replace the needle too. Otherwise the old needle can damage the new nozzle on day one.

Not every spray problem is the nozzle. Spitting is also caused by paint that's too thick, pressure that's too low, a dried-up nozzle cap, or a missing nozzle seal. Check those first. A nozzle is cheap, but it's still wasted money if it isn't the fault.

Want finer lines? 0.38 mm is a general-purpose size: base coats, shading, camouflage. For fine freehand detail, a dedicated 0.2–0.3 mm airbrush will do better than any nozzle swap on this one.
