Key points
Exact OEM dimensions
Produced to the original Gema drawing, so it drops straight into the EI 2 / EI05-V injector without any rework.
Wear-resistant material
Chosen for long service life under enamel powder abrasion, one of the main reasons the original part fails.
Keeps the injector sealed
Correct seating avoids air leakage around the sleeve, which is what makes powder output drop and coating become uneven.
Stable powder output
A tight, correctly toleranced sleeve keeps the air/powder mix consistent, so film thickness stays repeatable.
Product description
This is an aftermarket (non-OEM) Gema sleeve nut 405248 for the enamel powder injector types EI 2 and EI05-V.
The 405248 sleeve nut (also listed as insert sleeve nut) is the position 5 component of the Gema plug-in enamel injector. It is dimensioned to the original Gema part and can be used on the original Gema equipment directly.
Why the sleeve nut matters
The sleeve nut seals the injector body. Once it wears, air escapes around it, the air/powder ratio drifts and you start to see a thin or blotchy film, pulsating output and powder build-up at the nozzle. Replacing the sleeve is normally the cheapest fix before touching the whole injector.
Quality points
- Non-OEM part produced to OEM standard dimensions, fully compatible with original Gema injectors.
- Wear-resistant material for a long service life under enamel powder abrasion.
- Correct seating keeps the injector sealed, so air leakage is avoided and powder output stays stable.

Frequently asked questions
Is the 405248 sleeve nut an original Gema part?
No. It is an aftermarket replacement made to the original Gema dimensions. It fits and works in the EI 2 and EI05-V injectors, but it is not manufactured or supplied by Gema.
Which injectors does this sleeve nut fit?
The Gema enamel powder injector types EI 2 and EI05-V. It is the position 5 component of the injector.
What is the difference between a sleeve nut and an insert sleeve nut?
They are the same component under two common names. 405248 is listed as both “sleeve nut” and “insert sleeve nut” in Gema parts documentation.
How do I know the sleeve nut needs replacing?
Typical signs are unstable powder output, a thin or uneven film, powder escaping near the injector and a visible wear ring on the sleeve.
