Titan Sealing Component Replacement
Titan 0533403 is an OEM leather V-packing used in the fluid pump section of AirCoat 423 and compatible AirCoat spray systems . This precision-molded packing provides a critical dynamic seal between the displacement rod and the pump cylinder . The V-shaped profile allows the packing to expand under pressure, creating a positive seal that prevents fluid bypass during the pumping stroke . The leather material offers excellent conformability and self-lubricating properties, making it ideal for the high-pressure, reciprocating motion of the fluid pump . A worn, hardened, or damaged leather V-packing can cause fluid leakage, pressure loss, erratic pump operation, and reduced spraying efficiency . Replacing with this genuine OEM component restores proper sealing and pump performance.

|---|---|
| Product Overview | OEM Titan leather V-packing used in the fluid pump section of AirCoat 423 and compatible spray systems . Provides a dynamic seal between the displacement rod and pump cylinder . |
| Function | Creates a dynamic seal between the reciprocating displacement rod and the pump cylinder. The V-shaped profile allows the packing to expand under pressure, ensuring a positive seal that prevents fluid bypass during the pumping stroke . Leather material offers excellent conformability and self-lubricating properties, ideal for high-pressure, reciprocating motion . |
| Replacement Indicators | Signs that replacement is needed include visible fluid leakage from the pump area, loss of pressure, reduced output, erratic pump operation, excessive leakage from the top packing, and pump strokes that become faster on one stroke than another . The 423/620 Series Pumps should receive service as required if there is excessive leakage from the top packing . |
| Service Guidance | When servicing the pump assembly, remove the ball, retainer, and lower packing set, then remove the upper packing set, upper spring, and spring retainer from the pump block . The use of Titan Piston Lube (Part # 314-480) is recommended as an upper packing lubricant . Do not substitute oil, water or solvent for an upper packing lubricant . |

The 0533403 Leather V-Packing is a genuine OEM component for compatible AirCoat spray systems. This leather V-packing provides a dynamic seal between the displacement rod and the pump cylinder . Over time, the leather V-packing can become worn, hardened, or damaged due to normal operation, exposure to solvents, or contamination . A worn packing can cause fluid leakage, pressure loss, erratic pump operation, and reduced spraying efficiency . 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 for an upper packing lubricant . This part is not listed as a component for the Commander air-powered airless sprayer. Refer to your product manual for detailed information about this component.
