Titan 235-028 Rod Seal
OEM Titan Hydraulic Motor Seal
Titan 235-028 Rod Seal is an OEM seal that creates a tight barrier around the piston rod in the hydraulic motor assembly of compatible PowrTwin, PowrLiner, and PowrTex sprayer models, maintaining high operating pressure and preventing fluid leaks.
Compatibility Overview
Prevents fluid leaks around the piston rod while maintaining hydraulic pressure. A worn or damaged rod seal causes pressure loss, fluid seepage, and erratic spray performance. OEM replacement restores proper sealing and reliable hydraulic motor operation.

Titan 235-028 Rod Seal for Hydraulic Motor Service
Titan 235-028 is an OEM rod seal used in the hydraulic motor assembly of compatible PowrTwin, PowrLiner, and PowrTex sprayer models. Documented as item 24 "Seal, Rod" in the hydraulic motor parts breakdown of official Titan service manuals for PowrTwin 5500 and as "Rod seal" in the PowrLiner 9900XLT manual, this seal creates a tight barrier around the piston rod to maintain high operating pressure and prevent paint or fluid leaks. It is included in the Motor Service Kit Minor (P/N 235-050). During hydraulic motor service, the rod seal should be inspected for wear, hardening, or damage, and replaced whenever the motor is disassembled for rebuild. When the original rod seal fails, fluid can leak past the piston rod, causing pressure loss, reduced spray performance, and potential damage to adjacent components. This replacement restores proper sealing and reliable hydraulic motor operation.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan rod seal used in hydraulic motor assemblies to create a tight seal around the piston rod, maintaining operating pressure and preventing fluid leaks. |
| Function | Seals the piston rod as it reciprocates through the motor/pump block, preventing hydraulic fluid from bypassing and maintaining system pressure. |
| System Location | Hydraulic motor section, piston rod assembly. Listed as item 24 in official Titan parts breakdowns for PowrTwin and PowrLiner models. |
| Industrial Applications | Hydraulic motor repair, fluid section rebuild, preventive maintenance on high-pressure airless sprayers, and fleet equipment restoration. |
| Documented Compatible Models | PowrTwin 12000 Plus/Plus DI/GH/GHD/XLT/XLT DI, 8900 Plus/GH/XLT, 6900 GH/GHD/XLT/DI, 5500, 4900 Plus/GH/XLT, 4500, 3500/3500 50th Anniversary/3500-DC; PowrLiner 8900/XLT SP, 6950, 6900 XLT/XLT SP, 6000, 5000, 4950, 4900 XLT, 4000, 4955, 6955, 8955; PowrTex 6900SF, 12000SV, 1200SV. Verify your exact model and revision against the service manual before ordering. |
| OEM Part Number | 235-028 Rod Seal (Seal, Rod). |
| Common Problems Solved | Fluid leakage around the piston rod, loss of hydraulic pressure, reduced spray performance, erratic pump operation, and fluid seepage at the motor/pump block. |
| Replacement Indicators | Visible wear, hardening, cracking, or flattening of the seal; fluid leakage at the rod; inability to maintain pressure; or during any hydraulic motor rebuild. |
| Related Parts Commonly Serviced Together | Piston (235-014), piston seal (235-027), piston rod (235-948), lower seal, O-rings (235-026, 441-217), and other components included in Motor Service Kit Minor (235-050). |
| Installation Notes | Install the rod seal in the motor/pump block with the open portion facing upward (V). Lubricate with hydraulic fluid before assembly. Inspect the piston rod for nicks or scratches that could damage the new seal during installation. |
The 235-028 Rod Seal is a critical sealing component in the hydraulic motor assembly. Inspect it during any hydraulic motor service for wear, hardening, or fluid leakage. Replace whenever the motor is disassembled for rebuild, as reusing a worn seal risks pressure loss and fluid leaks. Always lubricate the seal and inspect the piston rod surface before installation. Verify model compatibility against your Titan service manual, as hydraulic configurations vary across sprayer platforms.
