Titan 178-001A Upper Packing Set for Admiral, Commander, HydraPro, and PowrCoat Systems
Titan 178-001A is an OEM upper packing set featuring leather and polyethylene construction, engineered to seal the upper pump area around the displacement rod in compatible Admiral, Commander, HydraPro, PowrCoat, Big 440, Boss, and PowrMastic spray systems. This packing set rides around the displacement rod, maintaining a tight seal so pressure builds on the stroke instead of leaking past the rod. It is the highest-frequency wear point in the fluid section. Official Titan service documentation specifies that the upper packing set should be inserted into the motor/pump block with the peak of the "V" packings pointing up toward the motor, and that leather packings must be soaked in oil before installation.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan / Speeflo upper packing set for fluid pump sealing and maintenance. Listed as "Upper packing assembly, leather/polyethylene" in PowrCoat operating manuals. |
| Function | Seals the upper pump area around the displacement rod to help maintain pressure response and reduce fluid bypass. Leather and polyethylene construction conforms to the rod surface and provides reliable sealing across a wide range of coatings. Official service documentation notes that earlier servicing is required if there is excessive leakage from the top packing or if pump strokes become faster on one stroke or the other. |
| Compatible Systems | Admiral 40:1 / 185-551 Fluid Pump Assembly; Commander 30:1 and 40:1; HydraPro III, IV, Super; PowrCoat 730, 940; Big 440; Boss; PowrMastic 40:1. Verify fit using the correct parts diagram for your exact model and serial number. |
| Related Parts Commonly Serviced Together | Upper packing spring, displacement rod, pump block, lower packing set, O-rings, valve balls, and service kits. Always inspect the displacement rod every time you repack—a scored rod destroys fresh packing quickly. |
| Common Problems Solved | Upper pump leakage, fluid bypass, pressure loss, poor sealing, premature rod wear, weak output, and repeated pump service issues. Official documentation notes that earlier servicing is required if there is excessive leakage from the top packing. |
| Signs Replacement Is Needed | Excessive leakage from the top packing, fluid bypass, pressure loss, poor sealing, and premature rod wear. Titan documentation specifies that earlier servicing is required if pump strokes become faster on one stroke or the other. |
| Installation & Maintenance | Official Titan service documentation specifies: all leather packings must be soaked in oil for 15-20 minutes before installation. Insert the upper packing set into the motor/pump block with the peak of the "V" packings pointing up toward the motor. Place the upper packing spring into the block with the small tapered end facing up. Titan Piston Lube (P/N 314-480) is recommended as an upper packing lubricant. Do not substitute oil, water, or solvent for an upper packing lubricant. |
| Commercial Benefits | Helps contractors restore pump sealing, protect displacement rod surfaces, reduce downtime, improve rebuild quality, and maintain reliable spraying productivity. |
The 178-001A Upper Packing Set is a critical wear component in the fluid sections of Admiral, Commander, HydraPro, PowrCoat, Big 440, Boss, and PowrMastic sprayers. Official Titan service documentation specifies that the pump should receive routine servicing after approximately 1,000 hours of use, with earlier servicing required if there is excessive leakage from the top packing or if pump strokes become faster on one stroke or the other. All leather packings must be soaked in oil for 15-20 minutes before installation. Insert the upper packing set into the motor/pump block with the peak of the "V" packings pointing up toward the motor. Titan Piston Lube (P/N 314-480) is recommended as an upper packing lubricant—do not substitute oil, water, or solvent. Always inspect the displacement rod every time you repack; a scored rod destroys fresh packing quickly. Use genuine Titan components to ensure proper fit, correct material specifications, and reliable long-term operation.
