Titan 0551669 Piston Rod
OEM Titan Pump Component
Titan 0551669 Piston Rod is an OEM replacement piston rod for the fluid section of compatible Titan and SprayTECH sprayers. This precision-machined rod connects the piston to the drive mechanism and reciprocates within the fluid section housing to pressurize and move material through the pump.
Compatibility Overview
Replacing a worn or scored piston rod restores proper sealing, eliminates fluid bypass, and maintains consistent pump pressure and efficiency.

Titan 0551669 Piston Rod for EPX2355 Fluid Section Assembly
Titan 0551669 is an OEM piston rod designed for the fluid section of compatible Titan and SprayTECH airless sprayers. This precision-machined component connects the piston to the drive mechanism and reciprocates within the fluid section housing to pressurize and move material through the pump. It is listed in the official EPX2355 Fluid Section Assembly (P/N 0551675) parts diagram as item 8.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan/SprayTECH 0551669 piston rod. Listed in the official EPX2355 Fluid Section Assembly (P/N 0551675) parts diagram as item 8, quantity 1. Bedford Precision confirms it as a replacement rod for the EPX2355. |
| Function | Connects the piston to the drive mechanism (slider/crankshaft). Reciprocates within the fluid section housing to pressurize and move material through the pump. The smooth surface finish is critical for proper sealing against the upper and lower packings. |
| Compatible Models | Titan/SprayTECH EPX2355 (Upright Cart configuration, Fluid Section Assembly P/N 0551675). Verify fitment against your specific model parts diagram before ordering. |
| Common Failure Symptoms | Visible scoring, scratches, or wear marks on the rod surface. Fluid leaking past the packings despite new seals. Loss of pump pressure or inconsistent spray output. Difficulty achieving proper packing seal due to rod surface damage. |
| Service Guidance | Inspect the piston rod for scoring or wear whenever servicing the fluid section. A scored rod will damage new packings and prevent proper sealing. When replacing the piston rod, always install new packings (upper and lower) and inspect the fluid section housing for wear. Follow the service manual for proper assembly and torque specifications. |
| Related Parts Serviced Together | Upper packing kit (0551677), lower packing, fluid section housing (0551681), piston, and all seals and gaskets. Consider a complete fluid section rebuild for comprehensive service. |
| Commercial Benefits | Restores proper pump sealing, eliminates fluid bypass and pressure loss, prevents premature packing wear, and extends the service life of the fluid section. |
The 0551669 Piston Rod is a critical replacement for contractors and service technicians maintaining compatible Titan and SprayTECH sprayers. If the pump loses pressure, leaks fluid past the packings despite new seals, or exhibits inconsistent spray output, the piston rod may be scored or worn. A damaged rod surface will quickly destroy new packings, so it must be replaced whenever significant wear is detected. When replacing the piston rod, always install new upper and lower packings and inspect the fluid section housing for wear. Replacing a worn piston rod promptly restores proper pump sealing and reliable spray performance.
