Titan part 600-099 is a shaft spring seal used to prevent fluid leakage along rotating or reciprocating shafts on compatible PowrTex diaphragm sprayers. Common applications include pump shafts, valve stems, and actuator rods where a dynamic seal with spring-loaded lip is required.

The Titan 600-099 Shaft Spring Seal is an OEM dynamic seal designed for PowrTex 300dd and 600dd diaphragm sprayers. It features a flexible lip held against the shaft by an internal garter spring, providing excellent sealing performance on rotating or reciprocating shafts such as pump drives, valve stems, and actuator rods.
Shaft seals can wear, harden, or lose spring tension over time, leading to fluid leaks, pressure loss, or contamination. A leaking seal can also allow air ingestion into the pump, causing erratic operation. Replacing with an OEM shaft spring seal restores proper sealing and protects internal components.
| Dynamic sealing | Prevents fluid leakage along a rotating or moving shaft |
|---|---|
| Spring‑loaded lip | Maintains constant contact with shaft despite wear |
| Contamination barrier | Keeps dirt and debris out of the sealed housing |
| Visible fluid leakage | Oil, paint, or solvent seeping past the shaft |
|---|---|
| Hardened or cracked lip | Seal material feels brittle or shows cracks |
| Spring dislodged or corroded | Internal garter spring broken, rusted, or missing |
| Grooved shaft wear | Shaft shows a wear groove; seal and shaft may both need replacement |
Titan part 600-099 is a direct replacement shaft spring seal for the following PowrTex models. Verify the seal dimensions (shaft diameter, housing bore) using your sprayer's parts diagram.

When replacing a shaft spring seal, inspect or replace these associated components for a complete repair.
Check the shaft for grooves, scoring, or rust. A damaged shaft will quickly ruin a new seal; polish or replace the shaft if needed.
Ensure the seal bore is clean and free of burrs or scratches. Use sealant on the outer diameter if specified.
Excessive shaft play from worn bearings can cause seal leakage. Replace bearings or bushings at the same time.
