The 4540 uses 02414183 (minor) and 02414180 (major). The 7230 uses 2414182 (minor) and 2414181 (major). Both models also have PTFE and valve kits listed. Buy a kit when you need several fluid section parts at once, and a single part when one named part has failed. The numbers differ between models, so order from your model's diagram.
Why kits exist
A Hydra X fluid section has two groups of wear parts: the packings that seal the piston, and the balls and seats that make up the valves. Replacing them one at a time means building a list from the diagram and ordering each number separately. A service kit puts a set of parts under one number so you order once, with the section already open on the bench.
This guide is deliberately light on what is inside each kit. Titan's kit contents are not something we publish here, and a guessed parts list is worse than none. Names below are exactly how the site lists each kit. Open the product page for what it covers, or call (713) 931-0006 and ask before you order.
The kits side by side
The 4540 and 7230 each have their own fluid section diagram, 4540 Fluid Section and 7230 Fluid Section, and the kit numbers follow the same split.
Hydra X fluid section kits as the site lists them
| Kit type | Hydra X 4540 | Hydra X 7230 |
|---|---|---|
| Minor | 02414183 Fluid Section Service Kit, minor | 2414182 Fluid Section Service Kit, Minor |
| Major | 02414180 Fluid Section Service Kit, Major | 2414181 Fluid Section Service Kit, Major |
| PTFE or leather | 02420804 Fluid Service Kit, Minor PTFE | 2420803 Fluid Section Service Kit (PTFE, Leather) |
| Outlet valve | 02414184 Outlet Valve Assembly | 2414185 Outlet Valve Assembly Service Kit |
| Foot valve | 02414186 Foot Valve Assembly | 2414187 Foot Valve Assembly Service Kit |
The PTFE row compares two items whose titles differ, so do not treat them as exact equivalents. On the 4540 the valve items are titled as assemblies rather than service kits; the 7230 titles say service kit.
Two things in that table are easy to miss. First, the 4540 numbers in this table start with a zero and the 7230 numbers do not, so a stray leading zero is a quick sign you are looking at a 4540 kit. Still confirm with the diagram. Second, the 4540 valve items are titled as assemblies, so do not assume they are a bag of small parts. Check the product page before you order.
Choosing between minor and major
Minor and major are Titan's names, and "major" suggests the more extensive kit. Beyond that, we cannot give you a list of what separates them, so we will not pretend to. What we can give you is a way to decide that does not depend on the contents.
Kit or single part?
| Situation | Better buy | Why |
|---|---|---|
| One named part is clearly damaged, such as the inlet ball or a seat | Single part from the diagram | You replace what failed. The diagram gives you the callout number. |
| The manual says to replace the packing set, for example after the pump chatters from a solvent-swollen upper packing | Ask about a kit | Titan's manual calls for the whole packing set in that case, and a kit may be the simplest way to get one set. |
| Only the outlet valve or the foot valve is suspect | Valve kit or assembly | The valve items are sold separately from the minor and major kits. |
| Several fluid section parts are due and the section is already open | Minor or major kit | One order covers the job and you avoid a second teardown. |
| Not sure what failed | Diagnose first | Use the symptom checks in Titan's manual before buying anything. |
The symptom checks are worth a minute. Titan's manual says that a pump delivering on the upstroke only points to the lower foot valve ball not seating, and delivering on the downstroke only points to the upper ball. The manual also says a pump that chatters has an upper packing swollen by solvent. A symptom that points to one ball is a single-part job. A symptom that points to the packing set is when you ask about a kit.
Matching the kit to the model
The site has a separate fluid section diagram for each model, and the part numbers inside them differ. The catalog also lists some 7230 kit pages with both the 4540 and the 7230 in their fitment notes. We are not going to tell you those kits do or do not fit the other model. The reliable approach is to start from the diagram for your model, take the kit number listed there, and call (713) 931-0006 if you want a second opinion before ordering for a 4540.
- Read the model off the sprayer tag. 4540 or 7230 is the whole decision.
- Open that model's fluid section diagram, not the one that looks closer.
- Take the kit number from that page.
- If the product page and the diagram disagree, ask the parts team before you order.
What is not a service kit
Three look-alikes turn up in searches. The 2401635A Fluid Section on the Motor / Pump Assembly page is the complete fluid section, not a repair kit. The conversion kits, 02424618 (4540 to 7230) and 2432905 (7230 to 4540), change the fluid section from one model's configuration to the other, and we do not list what is in them. And the Hydra M and Pro IV kits, such as 245-500 on the Hydra M4000 diagram, belong to the older sprayers. Do not mix those with Hydra X orders.
Order with the right consumables
A repair is the time to add the daily-use items. Titan's manual calls for Piston Lube in the packing oil reservoir, kept half full, and that is 314-480 on the site. If the sprayer has been opened for hydraulic work, Coolflo (430-361) is the only fluid Titan allows. The repair procedure itself is in Titan's Hydra X manual, available on our manuals page. Relieve pressure first, as the manual describes.

The Short Version
Find your model on the tag, open its fluid section diagram, and take the kit number from there. Use a kit when several fluid section parts are due at once, a single part when one named part failed, and a phone call when the product page and the diagram do not agree.
