The Elite 4500 pump assembly page lists 52 parts, covering the hydraulic housing, diaphragm assembly 2419185, paint head, inlet valves, valve repair kit 2419852, pressure controls, hoses and seals. Titan names the inlet and outlet valves as the wear parts. Find your part by its callout number on that page.
What the Elite 4500 pump assembly page covers
The Elite 4500 Pump Assembly page is the biggest diagram for this sprayer, with 52 parts. It applies to the 4500 frames 2407310 (High Rider) and 2407311 (Low Rider). The 4500 is a PermaStroke sealed hydraulic sprayer: Titan describes it as having no pistons, packings, cylinders or clutch, with a maximum of 3300 psi. Because there is no packing set to rebuild, the pump page reads differently from a piston-pump diagram, and most of its parts are housings, seals and controls.
Many of these listings also name the Elite 5500 in their fitment text. If you own a 5500, confirm the part on (713) 931-0006 rather than assuming, since we only list the 4500 on this diagram. The tables below give the callout number so you can match a part on the page to the picture.
Hydraulic section
These are the parts of the hydraulic side. One description of the design says a piston moves hydraulic oil beneath the diaphragm, and the diagram lists the pieces around that. We do not give an oil type, quantity or change interval for this section, so use your owner's manual for those.
Hydraulic housing and related parts
| Part | Number | Callout |
|---|---|---|
| Hydraulic housing | 2389127 | 9 |
| Sealing housing | 2367485 | 8 |
| Piston D26 | 2401832 | 35 |
| Insert pressure D26 assembly | 2401855 | 29 |
| Pressure insert | 2416706 | 39 |
| Oil dip stick | 2370128 | 27 |
| Oil screw plug | 341349 | 28 |
| Sleeve rubber | 2370116 | 32 |
| Compression spring | 34357 | 36 |
The diagram names a dip stick and an oil screw plug but does not say what oil to use. Check your manual.
Diaphragm and paint head
The 2419185 diaphragm assembly (GSH-33) is the part most people search for. On the same page you will find a 2395014 paint head assembly (GSH-33) at callout 46, a machined cover (2401092) at callout 7, and a front cover with label (2423844) at callout 2. A piece of foam (2404992) is listed at callout 3. The page also shows the 2419184 pulsation dampener, the FlatLine part Titan says smooths pressure fluctuations, at callout 42.
Valves and the repair kit
Titan says the two wear parts on a PermaStroke sprayer are the inlet and outlet valves, and that they are field serviceable with common tools. The pump page lists two inlet valve assemblies, 2411377 (callout 53) and 2409743 (callout 48), plus the 2419852 valve repair kit, which has no callout number. We do not list what is inside the kit beyond its name, so confirm the contents before you buy.
For the individual valve pieces, switch to the Inlet Valve Body and Outlet Valve pages. An extract of Titan's 4500 manual says the outlet valve is removed with a 22 mm wrench and the inlet valve sits in its housing, held by a clip. Follow the manual for any removal.
Pressure controls and hoses
Pressure control and hose parts on the pump page
| Part | Number | Callout |
|---|---|---|
| Pressure control knob | 341219 | 23 |
| Stop sleeve | 0010859 | 24 |
| Pressure spring | 0010861 | 25 |
| Clamp or retaining clip | 0010858 | 22 |
| Control valve assembly | 252294 | 21 |
| Relief valve assembly | 169248 | 47 |
| HP hose DN3 | 2389782 | 16 |
| Return hose | 2389777 | 4 |
| Fitting | 97201 | 17 |
Titan's manual extract says the pressure relief procedure starts with locking the gun's trigger lock, turning the relief valve to PRIME (circulation) and turning the pressure control knob counterclockwise to minimum. It also warns that running higher pressure than you need to atomize causes premature tip wear and extra overspray. So the knob is a setting to check before you suspect a worn part.
Seals, O-rings and the second gun kit
- U seal 9970210 (callout 10) and seal 2369458 (callout 54), which also appears on the inlet valve body page.
- O-rings: 9971146 (26), 2368785 (13), 2410458 (14), 2337803 (37), 2368784 (38) and 3051678 (31). Several look alike in a photo, so match on the callout number.
- Sealing ring 341330 (callout 52), seal washer 9970103 (44) and protective cap 9990535 (51).
- 2424678A, the second gun kit for the Elite 4500 (callout 55). Titan lists the 4500 for up to 2 guns, with a 0.023 in. maximum tip at two guns. We do not list the contents of the kit.
Finding the right callout
Confirm it is a 4500
The model name and frame number (2407310 or 2407311) tell you this is the right page. A 3500 has its own pump assembly page with different numbers.
Group the symptom
Valve problems send you to the inlet or outlet valve pages, a pressure setting that is off sends you to the knob and control parts, and a hose leak sends you to the hose and fitting rows.
Match the callout
Find the numbered callout on the diagram and add that part to your cart from the table above or the page.
Call if unsure
Phone (713) 931-0006 with the model and serial number. The manuals page has the owner's manual for service steps.

The Short Version
The 4500 pump page is mostly housings, seals and controls because PermaStroke has no packings. The diaphragm (2419185) and the inlet and outlet valves are the parts to know, along with the 2419852 valve repair kit. Use the callout numbers to match each part, and relieve pressure first.
