Know your exact gun model first, then open that model's diagram on the site and order by the numbered callout. Next confirm the pressure rating, the size or thread, and whether you need a single part or a repair kit. Check the product name for notes such as Replaces or Aftermarket, and read the return terms. If any step is unclear, call (713) 931-0006 with the model.
Check 1: Name the gun exactly
"A Titan airless gun" is not enough to order from. The RX-80, RX-Pro and RX-Apex belong to Titan's Red Series; the S-3 and S-7 are S-Series; the M-4 and M-8 are mastic guns; the LX-40 and the inline gun 550-475 are entry-level; the GM 3600 is air-assisted airless. Each has its own diagram page on the site, and the repair kit for one will not be the repair kit for another.
Look at the gun body or the box for the model name, and note the part number on the label if there is one. Be careful with the RX-Pro and RX-80 because they look alike and are sold in several configurations. The RX-80 alone is listed as 0538005, 0538006, 0538007, 0538008 and 538009, which differ by trigger and tip. If you cannot tell which you own, have the model and serial number ready and call (713) 931-0006.
Check 2: Order from the diagram, not from memory
The site is built around Titan's parts diagrams. Open your model's page, find the numbered callout for the part and add that part. It beats searching by description, because names such as seal, filter and gasket repeat across many guns. Useful starting points are the RX-80, RX-Pro, RX-Apex, S-7 and M-4 and M-8 pages, or the entry-level guns page.
Write the part number down exactly as the site prints it. Leading zeros and suffix letters are part of the number: 0538204A, for instance, is the RX-Pro gun packing seal assembly, and the final A is part of what you order.
Check 3: Match the pressure rating
A gun's rating is only one link. The tip, the guard, the hose and the swivel each carry a rating, and the system is limited by the lowest. Titan lists the RX-80, RX-Pro and the 3600 psi guns at 3600 psi, the RX-Apex at 5000 psi, and the S-3 at 3900 psi. For guards, 0289228 is rated to 5000 psi and 661-027 to 7700 psi.
Hoses sit on separate pages by class: 3300, 3600, 4500, 6500 and 7500 psi. Before you buy a tip or hose for a higher-rated gun, compare it with the lowest rating already in your setup. The HEA and SC-6+ reversible tip pages on Titan's site print an inconsistent pressure figure, so for those tips check the rating on the tip's own packaging or ask us.
Check 4: Size, thread and inlet
Some parts exist in more than one size for the same gun name. Titan lists the S-7 as 550-260 with a 1/4 inch swivel and 550-270 with a 3/8 inch swivel; the M-8 also comes with 1/4 inch and 3/8 inch inlet fittings. Gun extensions use a 7/8 inch thread, and the RX guns use a 7/8 inch diffuser. If your hose or whip hose ends do not match the inlet, the part will not connect however well the model matches.
Check 5: Tip and filter details
For a tip, you need four facts: the family (TR1 reversible, SC-6+ reversible, HEA, high pressure, line striping or Brilliant Flat), the three-digit code, the thread or guard it fits and the rating. The first digit doubled gives fan width in inches at 12 inches; the last two are the orifice in thousandths of an inch. The 517 comes in several families on the site, such as 695-517 and 330-517A, and they are not interchangeable choices for one use.
For a gun filter, match the thread (unthreaded or threaded page) and then the mesh, which is colour coded: green 30, white 60, yellow 100, red 150. Titan says unthreaded filters fit guns including the RX-Pro, RX-80, S-3, S-7 and GM 3600.
Check 6: Single part or the model's kit
If one part is clearly damaged, order that part. If the gun leaks, spits or will not shut off and you cannot see why, a repair kit is the safer buy. The kits on these diagrams are 0538215 (RX-80), 550-275 (S-3), 550-276 (S-7) and 2348175 (M-4 and M-8). For an RX-Pro that leaks at the tip, Titan's manual points to the 0538221 ball valve kit rather than a full rebuild.
Check 7: Read the product name, then the terms
Product names carry notes. Some names, such as 0538005 and the RX-Apex non-filtered gun 0538070, say Replaces followed by an older Titan number: that is how to cross-match a number printed on an older gun. A name that says Aftermarket is not an OEM Titan part; 697-627 is labelled aftermarket from Bedford. The rest of the site's parts are described as genuine OEM manufacturer-supplied parts.
Last, the terms. A gun part ordered in error can be returned only with an RMA within 30 days of delivery, with a 30% restocking fee and your return shipping, and special-order items cannot be returned. Some items are ordered from the manufacturer after you order, so delivery dates are estimates. Details are on the shipping information page.
