Before ordering a sprayer part, have the model and serial number in hand, find the part on that model's parts diagram and use the number beside the callout, decide whether a kit or a single part is the better buy, and check that any hose, gun or tip guard is rated at or above the sprayer's pressure. Then read the returns terms. Call (713) 931-0006 if any step is unclear.
Gather the model and serial number first
Everything else depends on knowing which sprayer you have. Models come in generations, and a part for one generation can be wrong for the next. Find the model name and the serial number on the sprayer's label or in your manual before you open a single page.
Keep them next to you while you order. If the diagram does not settle the question, our parts team can confirm fitment by phone on (713) 931-0006, and they will ask for the same two things.
Find the callout on the parts diagram
The most reliable way to order is by diagram. Open Order by Titan Parts Diagram, pick the model, open the assembly the part sits in, find the numbered callout and add that part. Searching by a part's name alone is how people end up with the wrong one, because many parts have near-identical names.
The tip guards page shows the idea on a small scale: four tip guards, each tied to a numbered callout on the drawing, such as the 0289228 G-thread guard at callout 1 and the 450-100A adjustable guard at callout 3. Match the picture, then the number.
Kit or single part
The site lists a long run of items under repacking kits and piston rods: repacking kits alone has 73 parts and piston rods 52. The question is whether to buy a kit or one item.
- Buy a kit when the symptom points at the packings or several wear parts at once, because the pump is opened once and the set is matched. Examples: 704-564 Upper Packing Kit or 144-050 Fluid Section Minor Service Kit.
- Buy a single part when inspection shows one damaged item, such as a scored 704-551A piston rod. A piston rod and a piston assembly are separate items on the site, so do not assume one includes the other.
- Check what a kit contains on its product page or by phone. A name like Minor Service Kit does not tell you what is inside.
A scored piston rod destroys new packings, so inspect the rod before you spend money on seals. The right order is rod first, then packings.
Pressure ratings and replacement notes
Never run a component above the lowest working-pressure rating in the system. That applies to the hose, the gun, the tip guard and the fittings: every replacement must be rated at or above your sprayer's maximum pressure, and hose must be airless-rated and conductive, as the manufacturer specifies. Look at the rating printed on the part.
Product pages also carry replacement notes. The 0291006 hose is listed as replacing Titan 690-375-50, and 538072, an RX-Apex gun, hose and tip kit, is listed as replacing Titan 0550075 and 550-110. A note like that tells you an old number has a current one. It is not a statement that a different part fits.
Genuine OEM numbers and returns
AllTitanParts sells genuine OEM parts, and each listing gives the part number and compatibility notes to help with fitment. For anything that holds pressure, prefer the OEM number your diagram shows over a universal substitute, and check the rating either way.
Know the returns terms before you order, not after. In short: request an RMA within 30 days of delivery, expect a 30% restocking fee plus return shipping on a part ordered in error, and note that special-order items and installed or used parts are not returnable. The full terms are on the shipping and returns page, which also explains that some items are ordered from the manufacturer after your order is placed, so availability on the site does not always mean an item is on a shelf.
A pre-order checklist
- Model name and serial number written down.
- The symptom noted: what the sprayer is doing, and what you have already checked.
- The right assembly page opened on the model's own diagram.
- Part number taken from the numbered callout, not from the name.
- Kit or single part decided, and the kit contents confirmed.
- Hose, gun and tip guard ratings at or above the sprayer's maximum pressure.
- Replacement notes on the product page read.
- Returns terms read.

The Short Version
Model and serial number first, then the diagram callout, then kit or single part, then pressure ratings, then returns terms. If any step is unclear, call (713) 931-0006 before you pay, not after the part arrives.
