The biggest published difference is the pressure rating: Titan lists the RX-Apex at 5000 psi (34.5 MPa) and the RX-Pro at 3600 psi (24.8 MPa). The Apex adds an adjustable grip and a built-in swivel. The RX-Pro comes with both trigger styles in the box. Your sprayer and hose ratings decide which one you can use.
The short answer
Titan describes the RX-Apex as a premium spray gun built for high volume commercial and industrial work, rated for 5000 psi (34.5 MPa). The RX-Pro is rated for 3600 psi (24.8 MPa). Both are Red Series guns, and both use Titan's Infinity Packing design. If your whole spray system is rated for 3600 psi or less, the Apex's higher rating is not something you can use, and the choice comes down to the grip, swivel and filter options below.
Side-by-side comparison
RX-Apex and RX-Pro as Titan publishes them
| RX-Apex | RX-Pro | |
|---|---|---|
| Maximum pressure | 5000 psi (34.5 MPa) | 3600 psi (24.8 MPa) |
| Trigger | All-Day Trigger, two-finger on the guns we list | Ultra-light Trigger; comes with both two-finger and four-finger triggers |
| Grip | FingerPrint+ Grip, fully adjustable | FingerPrint Grip, customizable; small, medium and large sold separately |
| Packing | Infinity Packing | Infinity Packing |
| Swivel | Free-Flow Swivel built in | Swivel part 0538205 on the diagram |
| Filter | Filtered 0538075 or non-filtered 0538070 | Takes the unthreaded gun filter |
| Tip guard | No-build tip guard | No-build tip guard |
Titan's own trigger comparisons use percentages that differ between its pages, so we give none. Specs are Titan's published figures; check your gun's manual.
Swivel and filter
Titan calls the RX-Apex swivel the Free-Flow Swivel and says the Apex is the only direct feed airless gun with a built-in swivel. That is Titan's statement. It does not mean the RX-Pro has no swivel: the RX-Pro diagram lists a swivel, part 0538205, at callout 23.
On the filter side, you choose when you buy an Apex. The site lists a filtered version, 0538075, and a non-filtered version, 0538070. The Apex manual says to clean the filter after each use. The RX-Pro takes the unthreaded gun filter in Titan's filter listing.
Parts the two guns share
The two diagrams have more in common than the gun bodies suggest. These numbers appear on both the RX-Pro list and the RX-Apex lists:
Some parts do not carry over. The RX-Apex lists its own full needle valve Infinity Packing kit, 0538253, and its own grips. Having a part number in common is a guide, not a promise that a part from one gun fits the other, so check the callout on the diagram for your gun.
Pressure rating matters most
A gun's pressure rating is only useful if the rest of the system is rated for it. Never run any component above the lowest working-pressure rating in the system, and that includes the hose, gun, tip guard and fittings. A 5000 psi gun on a sprayer or hose rated for less gains you nothing, so a higher-rated gun is not a reason to buy for a lower-rated system.
Which to choose
- RX-Pro if your system tops out at 3600 psi, you want both trigger styles included, or you want to size the grip for your hand.
- RX-Apex if your sprayer and hose are rated for it, you spray high volume commercial or industrial work, and you want the adjustable grip and built-in swivel.
