The RX-80 and RX-Pro are rated 3600 psi and the RX-Apex 5000 psi. Titan lists its unthreaded gun filter for the RX-80 and RX-Pro; the RX-Apex diagram lists the 581-060 white filter. The RX-80 and RX-Pro diagrams list tip guard 0289228. Kit hoses are 3300 psi on the RX-80 and RX-Pro kits and 6500 psi in the RX-Apex 538073 kit.
What Titan calls the Red Series
Titan groups three guns as its Red Series: the RX-80, the RX-Pro and the RX-Apex. The GM 3600, LX, M and S guns are in a separate group it calls Specialty Airless Guns. The three Red Series guns are rated differently:
Red Series ratings as Titan lists them
| Gun | Maximum pressure | Where to order |
|---|---|---|
| RX-80 | 3600 psi (24.8 MPa) | RX-80 guns |
| RX-Pro | 3600 psi (24.8 MPa) | RX-Pro guns and accessories |
| RX-Apex | 5000 psi (34.5 MPa) | RX-Apex guns and accessories |
Every accessory you add has its own rating. The lowest rating in the system, not the highest, is the limit.
Gun filters
Titan lists its unthreaded gun filter for the RX-Pro and RX-80. The colour is the mesh: green 30, white 60, yellow 100 and red 150. Titan says the filter helps reduce tip plugging. The site carries 581-059 (green), 581-060 (white), 581-062 (yellow), 581-061 (red) and the 2-pack 0089959 (yellow, 100 mesh). All of them are on the unthreaded gun filters page.
The RX-Apex is separate. Its 0538108 diagram lists the 581-060 white filter, and Titan sells it both filtered (538075) and non-filtered (538070). We are telling you what the diagram lists, not claiming the Apex takes every filter the RX-Pro does. The RX-Apex manual says the filter must be cleaned after each use.
Tip guards and tip seals
The RX-80 and RX-Pro diagrams both list 0289228, a G-thread tip guard. Titan rates its No Build Tip Guard, 289228, up to 5000 psi (34.5 MPa), and its HP guard, 661-027, up to 7700 psi (53 MPa). The tip guards page has all of them. Both diagrams also list the tip seals 651-020 and 0297007.
A guard rated higher than the gun is allowed: a 7700 psi guard on a 3600 psi gun is fine. It does not raise the gun's own rating, so the RX-80 and RX-Pro still top out at 3600 psi.
Tips that Titan pairs with them
The RX gun configurations Titan lists come with a 517 tip. Among RX-80 and RX-Pro configurations there are 517, SC-6+ 517 and HEA 517 versions, and the RX-Apex has a 517 high-pressure tip kit, 538073. A 517 means a fan of about 10 inches at 12 inches from the surface with a 0.017 in. orifice. The tip families are on these pages:
- TR1 reversible tips, for example 695-517
- SC-6+ reversible tips
- TR1 HEA tips, for example 330-517A
- TR1 high pressure tips, which Titan rates up to 7700 psi (53.1 MPa)
Titan prints no reliable maximum for the HEA and SC-6+ reversible tips, so check the rating on the tip you buy against the lowest rating in your system.
Hoses in the kits
The RX-80 and RX-Pro gun, hose and tip kits include a 50' x 1/4 in. 3300 psi airless hose and a 3' whip hose. The RX-Apex 538073 kit comes with 6500 psi hose and the 517 high-pressure tip. Titan sells airless hose in 3300, 3600, 4500, 6500 and 7500 psi classes. Never use a hose, gun, tip or guard rated below the pressure you are running.
Extensions and poles
Titan's aluminum gun extensions and its high-pressure gun extensions fit guns with a 7/8 in. thread. The site lists the RX-80 and RX-Apex diffusers as 7/8 in., so extensions are worth considering on those. Confirm fit on your own gun by phone before you order, and check the extension's rating, since Titan rates aluminum extensions at 3600 psi and the high-pressure alloy steel ones at 7500 psi.

The Short Version
RX-80 and RX-Pro: 3600 psi, unthreaded gun filter, guard 0289228. RX-Apex: 5000 psi, 581-060 white filter on its diagram. Kit hoses are 3300 psi except the Apex 538073 kit at 6500 psi. Always stay within the lowest rating in the system.
