Part 641-003 is a replacement tip seal for HVLP Airspray ProFinish AS1130 spray guns. This seal prevents material from leaking around the fluid tip, ensuring proper atomization and a clean spray pattern. When the original seal becomes worn, cut, or hardened, replacement restores leak-free performance.

The 641-003 tip seal is a direct replacement sealing component for HVLP Airspray ProFinish AS1130 spray guns. This precision seal is installed between the fluid tip and the gun body, creating a leak-proof barrier that prevents material from escaping around the tip. Proper sealing at the tip is essential for maintaining correct fluid pressure at the nozzle and achieving optimal atomization. When the tip seal is functioning correctly, all material is directed through the fluid tip and air cap for a consistent, well-defined spray pattern. A worn, cut, or hardened tip seal can allow material to leak, causing drips, spitting, and an uneven spray pattern. It can also lead to material buildup around the tip, affecting air flow and further degrading performance. This replacement seal is manufactured from material compatible with a wide range of coatings and resistant to compression set. Installation requires careful cleaning of the sealing surfaces and proper seating of the new seal. Regular inspection during gun cleaning helps identify tip seals that need replacement before they affect finish quality.
