The parts at the gun wear first: the TR1 line striping tip, the tip seals, the gun filter and eventually the gun itself. A worn tip loses pressure and gives a coarse or streaky line. On the 3500 these are 697-419, 651-020 or 0297007, 0089957 and 0538014. Replace by symptom, never exceed your model's maximum tip size, and match the hose to the machine's pressure.
What is in the box
Titan ships the PowrLiner 3500 with one RX-80 gun, a 419 line striping tip and a 1/4 in. x 50 ft hose. The hydraulic 4955, 6955 and 8955 come in a two-gun configuration with S-3 guns and the same size and length of hose, per dealer listings. That is your starting kit, and it tells you what to stock: whatever is on the gun end gets used first.
TR1 line striping tips
Titan's line striping tips for these machines are the TR1 reversible tips, and the 419 is the one that ships with the 3500. The site lists 697-419 on the 3500 and 3500S main assembly pages. The wider range, including 697-415, 697-619, 697-421 and 697-621, is on the 6955 accessories page. The 850 and 550 pages carry their own TR1 lists. Titan does not publish what the tip digits mean in our sources, so we will not guess; read the number off the part you want and match it.
Two general facts help you buy. The orifice size controls how much material the tip delivers, and the fan angle controls the width of the line. A worn tip has a wider orifice, so pressure falls, the line comes out coarse or streaky and the machine uses more paint. When the line degrades, replace the tip before you adjust anything else. A reversible tip can clear a clog by rotating the handle as the tip's instructions describe.
We do not match a tip number to a coating here. Titan's published material does not give that pairing in our sources, so use the manual and the coating maker's guidance.
Tip seals and guards
- 651-020 and 0297007 tip seals. The 0297007 is listed as the replacement for an earlier Titan tip seal number. Both appear on the 3500 main assembly page.
- 661-020 Tip Seat and Seal Kit (5 pack), on the 3500/3500S accessories page.
- 0289122 tip guard assembly on the 3500 main assembly page, and 0289228 tip guard, G-thread, on the accessories page.
Keep the tip guard fitted at all times. It is a safety device, not an accessory: fluid injected through the skin is a medical emergency, so never spray without it.
Guns and gun filters
The 3500 main assembly lists the 0538014 gun assembly. The 3500/3500S accessories page lists RX-80 airless spray guns as 0538006 and 0538005, and a 550-250 S-3 swivel spray gun. The 850 and 550 diagrams list a 759-369 gun assembly. The hydraulic models have a gun holder assembly page, and the second gun kits, such as 759-138, are listed on their accessories pages. Because fitment differs by model and serial number, confirm the gun with our parts team at (713) 931-0006 before ordering.
Gun filters are the cheap part. The accessories page lists 0089957, a coarse green 2-pack, and 0089959, a 100 mesh yellow filter listed for use with the RX-80, S-3 and several other Titan guns. Clean the gun filter after every use: the 850 manual says warm soapy water for latex and mineral spirits for oil-based coatings, and the same habit is sound on any airless gun. A blocked filter causes pressure loss, pulsing and spitting.
Hose and pressure ratings
The rule that matters is that no part of the system may be rated below the machine's working pressure: hose, gun, tip guard and fittings. The 3500 and the hydraulic models are rated to 3300 psi, and the 850 to 3000 psi. Use airless-rated, conductive, grounded hose as the manufacturer specifies, and check the hose for cuts, kinks and bulges before work.
The standard spray hose on our diagrams is 316-505, the 50 ft spray hose, listed on the 3500 and 850 main assembly pages and in its fitment list for the 4955, 6955 and 8955 as well. The hydraulic pages list other hose parts under names such as Airless Paint Hose, for example 0290340 on the 8955 main assembly and 0290339 on its high pressure filter page. Check the callout on your model's page to see where each one connects.
Max tip size is a ceiling
Titan lists a maximum tip for each machine, and it is a limit, not a goal. For the 3500 it is 0.027 in. For the 8955 it is 0.054 in. with one gas gun and 0.038 in. with two. The 4955 and 6955 figures differ between sources, so we do not print them: take them from your manual. A bigger tip asks more of the pump than it can deliver, so pressure and pattern suffer.

The most common wear parts at the gun end:
The Short Version
Stock a spare TR1 tip, a tip seal or seat kit and a gun filter for whichever PowrLiner you run. Replace tips when the line goes coarse, keep the tip guard on, and never fit a tip above your model's maximum. Match the hose to the machine's pressure. Open your model's accessories or main assembly page for the exact number.
