Titan part 245-020 is a lower packing retainer designed to secure and position the packing stack within the fluid section of compatible Hydra M 2000, Hydra M 4000, Hydra Pro Super, Admiral, and Commander sprayers. This retainer holds the lower packings and spring in place, ensuring proper alignment and compression against the piston or plunger. Replacing a worn, cracked, or missing lower packing retainer restores correct packing geometry, prevents seal distortion, and ensures leak‑free pump operation.

The Titan 245-020 Lower Packing Retainer is a precision component that sits at the bottom of the packing stack in the fluid section of Hydra M, Hydra Pro Super, Admiral, and Commander sprayers. It provides a stable seat for the lower packing spring and packings, keeping them concentric with the piston bore.
Over time, the retainer can become worn, cracked, or deformed due to pressure cycling or improper installation. A damaged retainer allows packings to shift, leading to uneven seal wear, fluid bypass, and premature pump failure. Replacing with genuine Titan 245-020 restores proper packing alignment, ensures even spring force distribution, and extends the life of the seal stack.

| Wear protection | Prevents direct contact between spring and housing |
| Visible cracks | Cracks in the retainer body |
|---|---|
| Deformation | Retainer no longer flat or round |
| Wear grooves | Deep scoring from spring or packings |
| During fluid section rebuild | Replace as part of complete seal overhaul |

When replacing the lower packing retainer, consider inspecting or replacing these associated fluid section components.
Always replace upper and lower packings at the same time as the retainer.
Replace the spring (Titan 245-014) together with the retainer for a complete lower seal assembly.
Inspect the piston surface for scoring that may have damaged the retainer or packings.
