Titan 0533403 Leather V-Packing
Genuine Titan Pump Seal Packing
Titan 0533403 Leather V-Packing is an OEM leather sealing component used in the fluid pump section of the AirCoat 423 sprayer, providing a reliable high-pressure dynamic seal around the piston to maintain consistent pressure and prevent fluid bypass.
Compatibility Overview
Worn or hardened leather packings cause pressure loss, erratic spray patterns, fluid bypass past the piston, and reduced pump efficiency. Replacing with genuine OEM 0533403 restores proper sealing and reliable pump operation.

Titan 0533403 Leather V-Packing for AirCoat 423 Sprayers
Titan 0533403 is an OEM leather V-packing designed for the fluid pump section of the AirCoat 423 sprayer. This precision-formed leather seal creates a dynamic seal around the piston, preventing fluid blow-by and maintaining consistent output pressure. The AirCoat 423 uses six of these packings per pump (three upper and three lower), while the AirCoat 620 uses part 0533425 [citation:2].
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan leather V-packing used on AirCoat 423 sprayers in the fluid pump section. Provides a dynamic seal around the piston to maintain high pressure and prevent fluid bypass [citation:2]. |
| Function | Creates a dynamic seal around the piston to maintain high pressure; prevents paint or coating material from bypassing the piston; helps protect the piston rod and cylinder bore from abrasive fluid damage [citation:2]. |
| Material Properties | Leather construction provides durability, wear resistance, and reliable sealing under high-pressure conditions. Leather conforms to the rod and holds lubricant well [citation:2][citation:8]. |
| Compatible Titan Models | AirCoat 423. (AirCoat 620 uses part 0533425.) [citation:2] |
| Quantity by Model | AirCoat 423: 6 total (3 upper + 3 lower) [citation:2]. |
| OEM Part Number | 0533403 Leather V-Packing. |
| Replacement Indicators | Pressure loss, erratic spray patterns, reduced pump efficiency, fluid bypass past the piston, fluid visible around the piston rod, and worn or hardened leather packings [citation:2]. |
| Service Guidance | Soak leather packings in hydraulic oil for 15-20 minutes before installation. The peak of the "V" packings should face downward for lower packings upon reassembly. Inspect the piston rod for scoring before installing new packings; a damaged rod will quickly destroy fresh seals [citation:6][citation:8]. |
| Related Parts Commonly Serviced Together | Piston rod, cylinder, glands, spring retainer, O-rings, and other fluid pump components [citation:2][citation:6]. |
| Common Problems Solved | Pressure loss, erratic spray patterns, reduced pump efficiency, fluid bypass, worn or hardened leather packings [citation:2]. |
| Target Users | Professional finishing shops, cabinet and furniture painters, wood and metal finishers, and maintenance crews servicing Titan AirCoat sprayer systems. |
| Commercial Benefits | Restores proper sealing performance, prevents fluid leaks, maintains reliable pump operation, and reduces downtime for professional painters and finishers [citation:2]. |
When replacing the 0533403 Leather V-Packing, follow the procedures in your AirCoat 423 service manual. Soak leather packings in hydraulic oil for 15-20 minutes before installation. The peak of the "V" packings should face downward for lower packings upon reassembly. Inspect the piston rod for scoring or damage before installing new packings; a scored rod acts like sandpaper and will destroy fresh packings in a fraction of their expected life [citation:6][citation:8]. Lubricate all other parts of the packing set with hydraulic oil during assembly.
