Per Titan's manual, fill the PowrCoat packing oil reservoir half full each day with Titan Piston Lube 314-480, without overfilling, and do not substitute oil, water or solvent. Worn packings show as leaking at the wet cup, paint in the wet cup, or pressure that will not hold. The packing set or kit differs by model, so order from your own fluid pump page.
What the packings do
In a piston pump the rod moves in and out through packings that seal it. They are what let the pump build pressure instead of leaking past the rod, and the wet cup above them holds a lubricant that keeps them working. Titan describes the PowrCoat fluid section as having self-adjusting packings and a piston rod and cylinder with hard-chrome plating. Even so, packings are wear parts, and Titan does not publish a life for them in hours or gallons. Replace on symptoms and on what you see when you inspect, not on a calendar.
The daily routine
The routine is short. Titan's operating manual says to fill the packing oil reservoir half full with Titan Piston Lube before you spray, and not to overfill it so that it drips into the paint. It also says not to substitute oil, water or solvent. The Piston Lube part number is 314-480, and the site lists it on the PowrCoat 960 accessories page.
- Fill the reservoir half full with Piston Lube, as the manual says. Do not fill it to the brim.
- Do not use oil, water or solvent in its place.
- Keep it apart from the AirCare lubricator, which takes the lubricant your manual specifies for the air side.
Do the check at the start of the day, which is when it costs you nothing. A packing run dry wears quickly, and a reservoir that was overfilled can put lubricant into the coating.
Signs of worn packings
What a worn packing looks like
| What you see | What it points to |
|---|---|
| Coating leaking at the wet cup | Worn upper packings letting coating past the rod |
| Paint in the wet cup or the packing oil | Coating getting past the packings into the reservoir |
| Pressure that will not hold | Packings, but also the balls and seats, so check both |
| New packings fail again quickly | A scored or damaged rod; inspect the rod before repacking |
These are general piston pump signs. Your model's manual has the full troubleshooting table.
The rod is the part to look at before you buy anything. A rod that is scored or rough destroys a fresh set of packings in short order, so a leak that comes back after repacking is a rod question, not a packing one. Pressure that will not hold is less specific. A worn ball or seat produces a similar symptom, so check the inlet and piston valves too, using your model's fluid pump page.
Packing sets by model
The packing parts are not the same on every PowrCoat. This table shows only the packing column; to see which pump goes with which model, open the fluid pump page for yours.
Packing parts as the site's diagrams list them
| Model | Packing parts on the fluid pump page | Kit listed |
|---|---|---|
| 630 | 0533602 V-packing, leather; 0533603 upper packing, PTFE | None named |
| 730 and 940 | 178-001A upper packing set; 180-002A lower packing set | None named |
| 745 and 960 | 155-053A packing set, leather; the 960 also lists 155-052A upper packing assembly | None named |
| 975 | 138-052A upper packing assembly | 138-153A repacking kit |
| 1045 | 0533651 V-packing; 0533652 leather V-packing | 0533936 fluid pump repair kit |
| 1064 | 0533657 PTFE V-packing; 0533658 leather V-packing | 0533937 repair kit; 0533894 PTFE packing kit |
| 1072 | 0533663 PTFE V-packing; 0533664 leather V-packing | 0533938 service kit; 533895 packing kit |
The 730 and 940 pages list several packing sets and assemblies. Confirm with our parts team which one your pump needs. We do not list kit contents here, so ask before you buy.
Leather or PTFE
Look at the table again and you will see leather and PTFE V-packings listed as separate parts on the 630, 1045, 1064 and 1072. The diagram does not say which one your pump uses, and we do not say that either lasts longer or is better. Do not guess between them.
If you do not know which your pump has, the quickest answer is a phone call. Give us the model and serial number on (713) 931-0006 and our parts team will confirm the packing before you order. The same goes for the 745, 960 and 975, where the diagram names a leather set or a repacking kit and no PTFE option.
Repacking is a manual job
How you take the fluid section apart and put new packings in is written down in your model's manual, and we send you there on purpose. The sequence matters, and the manual shows it for your pump. Manuals are on our manuals page.
After repacking, flush the sprayer before spraying and refill the packing oil reservoir with Piston Lube as the manual describes. Our guide to packing kits and seals for Titan air-powered piston pumps covers the same parts across the wider air-powered range.

The Short Version
Top up the packing reservoir with Piston Lube each day as the manual says, and nothing else. When coating shows at the wet cup or pressure will not hold, check the rod and the valves as well as the packings. Then order the packing set or kit from the fluid pump page for your own model.
