Part numbers on the S-7 spray gun can look cryptic, but each one maps to a numbered callout on the parts diagram. This guide walks through the main S-7 part numbers and what each refers to. AllTitanParts.com is based in Houston, Texas. Most available items are processed for shipment within about 1-2 business days, though some are ordered from the manufacturer after you order (see Shipping Info).
Why Part Numbers Matter
Ordering by description alone, such as "trigger screw," can lead to the wrong part: the S-7 diagram lists both a short trigger screw and a long one, under different numbers. The part number and callout on the S-7 parts list remove the guesswork, which is why this guide walks through what the main numbers represent.
How to Read a Titan Part Number
We are not aware of a single code that decodes every Titan number across all product lines, so we do not recommend trying to read meaning into prefixes. The dependable approach is to cross-reference the number against the exploded diagram for your gun, then match the callout number printed on the drawing to the parts list beside it. On the S-7 page, the callout tells you where the part sits in the gun, and the part number is what you order.
Trigger and Lock Components
The S-7 parts list shows the trigger assembly, 4-finger gun, as 0502074 (callout 4), with the trigger guard 0296504 (callout 5). The trigger is held with two screws that carry separate numbers: the long trigger screw 0502068 (callout 2) and the short trigger screw 580-513 (callout 15). The end cap is 0502159 (callout 11).
Seal and Diffuser Components
The packing seal assembly and the diffuser are separate numbered parts on the diagram, so do not mix them up when ordering. The packing spring, 0502055, is also listed on the S-7 diagram (callout 12), and the gun repair kit 550-276 covers the common wear items together. The gun head, 0502064A, is the forward housing the other parts fit into.
- Packing seal assembly: 550-264 (callout 13).
- One-hole diffuser: 550-277 (callout 6).
- Gun head: 0502064A (callout 1).
- Gun repair kit: 550-276 (callout 19).
Numbers the S-3 and S-7 Share
The site's S-3 parts list and S-7 parts list show many of the same numbers. That is useful if you keep both guns in a fleet, but the lists also differ in places, so check each one.
| Part | S-3 list | S-7 list |
|---|---|---|
| Packing seal assembly | 550-264 | 550-264 |
| One-hole diffuser | 550-277 | 550-277 |
| Gun repair kit | 550-276 | 550-276 |
| Short trigger screw | 580-513 | 580-513 |
| Gun head | 0502077 | 0502064A |
| Packing spring | 0502054 | 0502055 |
Confirming Fitment Before You Order
Match the part number against the current parts diagram for your gun before purchasing, rather than relying on memory of a previous order or a general description. This matters most for seal and trigger components, where similar-looking parts can differ. For the model's own overview page, see the S-7 airless spray gun page, and for how the S-series differs, read S-3, S-5 and S-7 Gun Parts. The manuals are on the manuals page.
Replaced Part Numbers
Some listings note that a part replaces an earlier number. For example, the S-7 trigger guard 0296504 is listed as replacing Titan 580-532. If you are holding an old number from an earlier order or an old manual, search it, and look for this kind of "replaces" note in the listing before assuming the part cannot be found. If you cannot find a match, call us with your gun's model and serial number.
Keeping a Part Number Reference
For a business running several S-series guns, a simple sheet matching each gun to its confirmed part numbers saves time on every future order. Rather than re-verifying fitment from scratch, a reference built up over a few orders turns repeat purchases into a quick check against the diagram.
