Frequently Asked Questions
Check the gun’s model stamped on the handle or body. If it’s one of the listed Silver (e.g., 208-327, 220-954) or Flex (e.g., 218-132, 220-956) models, this is the correct kit. If your gun says Silver Plus or Flex Plus, you’ll need the corresponding “Plus” kit instead.
Basic hand tools are usually sufficient. Keep the work area clean, depressurize the system, and follow gun service instructions. Inspect the seat and needle for wear and replace all packings/seals provided in the kit.
Yes—if the spitting is caused by worn internal needle/packings. Also confirm your spray tip and tip seal are in good condition and that your gun filter is clean and sized for your coating.
No. The 218143 is for the original Silver and Flex guns. For Plus versions, use the appropriate “Plus” repair kit (e.g., 235474).
Flush thoroughly after each use, keep a clean/appropriate mesh gun filter, avoid dry-firing at high pressure, and replace tips and tip seals as they wear to minimize stress on the gun internals.
