Titan Fluid Sealing Component
Titan 0533540 is an OEM packing used in the fluid section of AirCoat 423 and AirCoat 620 airless spray systems. This sealing component prevents fluid bypass around the piston and maintains system pressure. Part number 0533540 cross-references to 533540.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan packing used in the fluid section of AirCoat 423 and AirCoat 620 spray systems. This sealing component creates a dynamic seal around the piston to prevent fluid bypass and maintain operating pressure. Part number cross-references to 533540. |
| Function | Creates a dynamic seal between the piston and the cylinder wall in the fluid section, preventing paint or coating material from bypassing the piston during the pressure stroke. The packing is an essential component for maintaining consistent system pressure and preventing fluid leakage past the piston rod or in the throat area. Over time, packings can wear, harden, or become contaminated. |
| Industrial Applications | Professional sprayer repair, fluid section maintenance, pump rebuilding, and preventive maintenance of AirCoat 423 and AirCoat 620 spray systems. |
| Compatible Titan Machines | AirCoat 423; AirCoat 620. |
| Accurate Part Number | 0533540 Packing (cross-references to 533540). |
| Compatible Parts & Assemblies | Fluid pump assembly, piston / displacement rod, cylinder, packing stack, and related sealing components in the fluid section. |
| Related Parts Commonly Serviced Together | V-packings, spring packing, piston seat, ball and ball seat, O-rings, and packing nut/gland. |
| Common Problems Solved | Loss of fluid pressure, pulsating or erratic spray output, fluid leakage from the pump throat or weep hole, and pump inefficiency caused by worn, hardened, or contaminated packings. |
| Use with Coating Systems | Supports AirCoat systems used by painting contractors, wood finishers, and industrial finishing professionals. The AirCoat 423 system delivers up to 2670 psi with a 23:1 pump ratio. |
| OEM & Brand Information | Genuine Titan OEM component designed for correct fitment in AirCoat series spray systems. The 423/620 Series Pumps should receive service as required if there is excessive leakage from the top packing, or if pump strokes become faster on one stroke or another. The use of Titan Piston Lube Part # 314-480 is recommended as an upper packing lubricant. Do not substitute oil, water, or solvent. When replacing packings, always inspect the displacement rod and cylinder for grooves, dents, or worn areas, and replace if hard chrome is damaged. |
| Commercial Benefits | Restores proper piston sealing, prevents fluid bypass, maintains consistent system pressure, ensures reliable spray performance, and extends equipment service life. |
