- Nozzle Body Collar — 1/4″-18 (710868-1) — a matched collar for smaller nozzle body threading.
- Mixing Tube Nut — Paser® ECL (014241-1) — secures the mixing tube, working in concert with the nozzle body structure.
Service tips: Over time, threads may experience wear or galling, so periodic inspection and replacement are recommended to avoid loosening or misalignment. Use only the matched nozzle collar for the correct thread size and ensure all sealing surfaces are clean and undamaged before assembly.
