Both are gas-engine Elite sprayers rated at 3300 psi. The 3500 lists 0.75 GPM, a GX120 engine, a 0.027" tip and 150-200 gallons a week. The 4500 lists 1.25 GPM, a GX160 engine, 200-300 gallons a week and use with up to two guns at a 0.023" tip each.
The Elite 3500 and 4500 look similar from across a job site and share a design: a gas engine driving a sealed hydraulic pump. The difference shows up in the numbers, in how many guns the sprayer feeds, and in which parts you order when something wears. One warning about sources first: Titan has a page for the 3500 but no page for the 4500, so the 4500 figures here come from dealer listings and from Titan's page for the Elite 5500, which lists the same figures. The 5500 is a separate model, not a renamed 4500.

3500 figures come from Titan's page. 4500 figures come from dealer listings and the Titan Elite 5500 page, which agree with each other.
Both ship with an RX-Pro gun, a 517 tip and a 1/4" x 50' airless hose. Both are built with PermaStroke Technology, which Titan says delivers top performance between 300 and 3300 psi with small or large tip sizes, and both list the FlatLine Pulsation Dampener and the Sureflo pusher valve. Engine horsepower and the 4500's weight are left out here because the sources do not agree.
One gun or two
This is the clearest dividing line. The 4500 sprays with up to two guns, and the listing gives a 0.023" maximum tip for each gun when running two. For the 3500 Titan lists only a one-gun tip size, so do not plan on running a second gun from a 3500.
The site lists a 2424678A second gun kit for the Elite 4500, shown on the 4500 pump assembly page. There is no matching kit on the 3500 diagrams. Running two guns also means the rest of the setup has to keep up. Every hose, gun, fitting and tip guard in the system needs a pressure rating at or above the sprayer's working pressure, which here is 3300 psi, and the tip pair you choose has to stay within the per-gun limit.
What the diagrams add
The 4500's pump assembly page lists 52 parts, against 37 on the 3500's pump assembly page. A few of the differences matter when you order:
- Valve repair kit: the 4500 page lists 2419852, named Valve Repair Kit 4500. The 3500 page lists 537903. The catalog's fitment line for 537903 names the Elite 3500, not the 4500.
- Inlet side: the 3500 has a pusher stem page (2369452 pusher, 2334383 inlet housing). The 4500 has an inlet valve body page with 2411377 inlet valve assembly GSH-33, 252279 housing, 341241 knocker for the inlet valve and 341330 sealing ring.
- Diaphragm assemblies: the 3500 page lists 340241 and the 4500 page lists a GSH-33 diaphragm assembly, 2419185. They are different numbers, so check the page for your model.
- Second gun: 2424678A appears only on the 4500 page.
- Engines: the main assembly pages list 980-332A on the 3500 and 980-331A on the 4500.
The filter pages differ in two small ways too. The 3500's high-pressure filter page lists an orifice (2365157) and a DM2-70 pulsation dampener (2429838). The 4500's page lists a 0.059" tip insert (2402215) and a different dampener, 2419184. Both pump pages also list the 169248 relief valve assembly and the 341219 pressure control knob, but check the callouts rather than assuming the two pages match.
Shared parts
The outlet valve is where the two diagrams overlap most. The 3500's outlet valve page and the 4500's outlet valve page list the same seven part numbers: seal 341347, seat 341327, spring support ring 253405, compression spring 341326, ball 9941501, O-ring 9971470 and clip 0341328. The 4500 page adds an outlet valve housing, 2342943. The 60-mesh manifold filter 730-067 and the filter housing 2429835 also appear on both filter pages.
Listed on both pages is not the same as proven interchangeable. Each part's own fitment note is what counts, and several 4500 pump and valve parts carry fitment notes naming the Elite 5500 rather than the Elite 4500. When you own a 4500, order from the 4500 page and phone (713) 931-0006 if the note on a product page does not name your model.
Which fits which job
Use Titan's own weekly figures as the guide, not a verdict. At 150-200 gallons a week the 3500 is the one-gun machine. At 200-300 gallons a week, and at 1.25 GPM, the 4500 is rated for heavier use and the only one of the two listed for a second gun. The 3500's 0.027" one-gun tip limit is also the number to check against your coating, and the manual is the place to confirm the coating itself.
Both are gas engines, so run and fuel them only outdoors or in a ventilated area and away from ignition sources. Titan's Elite 3500 manual lists an engine oil change after the first 20 hours and every 100 hours after, with 10W30 for general use; follow the Honda engine manual for your own engine.
Where to find each model's parts
Open the 3500 pages from the pump assembly, and the 4500 pages from its pump assembly. Cart pages are separate for each configuration: 0537012 and 0537013 for the 3500, 2407310 and 2407311 for the 4500. Manuals are on our manuals page.
Parts that are model-specific, plus the shared outlet valve parts:
The Short Version
Same pressure and the same sealed hydraulic design. The 3500 is the one-gun machine at 0.75 GPM, the 4500 is the larger one at 1.25 GPM that sprays with up to two guns. The outlet valve parts are listed on both diagrams; the pump, inlet side, engine and carts are not, so order from your own model's page.
