Here are the top 10 most frequently required spare parts for Gema powder coating guns, based on industry consensus and replacement trends:
1. Nozzles (flat & round jets) – Control spray pattern; most common wear part
2. Electrode holders – Secure the high-voltage electrodes; replaced often alongside nozzles
3. Injectors / Venturi tubes – Critical for powder fluidization and chimney wear-prone
4. O-rings and seals – Ensure airtight connections in hoses and injectors
5. Deflectors / air caps – Shape airflow, smooth wear areas
6. Powder hoses & tubing – Constant abrasion from powder; need regular replacement
7. Insert sleeves (Teflon/Tefzel) – Wear inside fluidizing pump; commonly replaced
8. Cascade – Connects gun body to injector; occasional wear/damage
9. Gun body components (back cover, trigger, cable) – Structural or control wear parts
10. Control module / HV contact ring – Electrical components that can degrade; replaced in severe cases
Why These Matter • Nozzles, electrode holders and injectors are closest to powder flow and high-voltage currents—major wear zones. • O-rings, sleeves, hoses safeguard airtightness and powder movement; these wear steadily with use. • Deflectors, cascades, and modules support spray quality and electrical integrity over time.
