Packing kits and seals for Titan's air-powered piston pumps maintain the seal around the displacement rod that lets the fluid pump build and hold pressure. The 155-053A leather packing set fits Admiral, Commander, PowrCoat 745, and PowrCoat 960, while other models use their own documented packing assemblies. AllTitanParts.com stocks genuine air powered packing kit options for the full lineup, with same-day shipping from Houston, Texas on orders before 3PM CST.

What Are Packing Kits & Seals?
Inside every air-powered piston pump — Commander, Admiral, or PowrCoat — the fluid section pressurizes coating by driving a displacement rod up and down through a packing stack. Packing kits and seals are the leather or synthetic rings that ride around that rod, maintaining a tight seal so pressure builds on the stroke instead of leaking past the rod. This is the highest-frequency wear point in any air-powered fluid pump, regardless of brand or model.
AllTitanParts.com stocks genuine air powered packing kit components for the full Commander, Admiral, and PowrCoat range, mapped to the exact assembly your machine uses.
Packing Fitment by Machine
Packing sets are not universal — the correct kit depends on your exact model and fluid pump assembly.
| Packing Kit | Type | Fits |
|---|---|---|
| 155-053A | Leather packing set | Admiral, Commander, PowrCoat 745, PowrCoat 960 |
| 138-053A | Upper packing set (leather) | Commander (155-559 fluid pump assembly) |
| 138-052A | Upper packing assembly | PowrCoat 975 (0533908 fluid pump assembly) |
| 138-153A | Repacking kit | PowrCoat 975 (0533908 fluid pump assembly) |
| 175-001A | Upper packing assembly | Admiral (181-556 fluid pump assembly, wall/drum mount) |
Before ordering, confirm your fluid pump assembly number from the data plate or your prior order history — the same machine model can pair with different fluid pump assemblies depending on ratio and configuration.
Upper vs. Lower Packing
Every fluid section packing stack has two functional groups. Upper packing seals the rod as it travels up through the pump body; lower packing seals the same rod on the downstroke. Because the two directions load different sealing surfaces, a pump can develop a clear directional symptom depending on which group is worn.
- Upper packing wear typically shows up as the pump moving up slowly and down fast.
- Lower packing wear typically shows up as the pump moving up fast and down slowly.
Symptom-to-Part Diagnosis
Directional stroke symptoms are one of the clearest diagnostic signals a fluid pump gives you — pay attention to which half of the stroke is affected before ordering parts.
| Symptom | Inspection Points | Recommended Action |
|---|---|---|
| Pump moves up slowly, down fast | Inlet ball, ball cage, upper packings, siphon connections | Clean and water-test the foot valve before replacing the ball or packing set |
| Pump moves up fast, down slowly | Piston ball, piston seat, lower packing set, rod threads | Test the piston ball and seat for sealing before replacing the lower packings |
| Pump cycles rapidly without material | Material supply, siphon hose, foot valve | Confirm material is reaching the pump before assuming a packing failure |
Why Leather Packing
Titan's air-powered pumps use leather packing rather than synthetic packing in most fluid sections because leather conforms to the rod surface and self-lubricates when kept wet with piston lube, giving it strong sealing performance across the wide range of coatings these machines handle. That's also why keeping the wet cup filled matters so much — dry leather packing hardens and loses its seal far faster than lubricated packing.
How Often to Repack
There's no fixed calendar interval for repacking an air-powered pump — wear is driven by cycle count, material abrasiveness, and how well the wet cup has been maintained, not by a fixed number of months. Watch for the signals instead: slow pressure loss under load, fluid appearing at the wet cup, or the directional stroke symptoms described above.
- Keep the wet cup filled with piston lube to extend packing life significantly.
- Repack proactively once you notice early directional symptoms rather than waiting for a full failure.
- Inspect the rod every time you repack — a scored rod destroys fresh packing quickly.
Repacking: What's Involved
A repacking job follows the same general sequence across Commander, Admiral, and PowrCoat fluid pumps: relieve pressure, disconnect the fluid pump from the air motor linkage, disassemble the pump block to access the packing stack, remove and inspect the old packing and the rod surface, install the new packing set in the correct orientation, and reassemble with fresh gaskets and O-rings rather than reused ones.
OEM vs. Aftermarket Packing
For packing specifically, genuine OEM is worth the difference. Titan's leather packing is compounded and cut to the exact dimensions of each fluid section, and it's rated to handle the solvents and coatings these machines pump. Generic aftermarket packing sets are a common cause of short service life and repeat repacking jobs, since a slightly wrong dimension or material compound won't seal as well or last as long.
Maintenance Habits That Extend Packing Life
- Never run the wet cup dry — this single habit does more to extend packing life than any other single factor.
- Flush thoroughly after every job with the correct solvent for the coating used, before the machine sits idle.
- Avoid letting coating dry in the fluid section — dried material accelerates wear on both packing and the rod surface.
- Check for directional stroke symptoms regularly, especially on machines in continuous industrial use, so packing service happens on your schedule rather than as an emergency.
