This Titan 800-355A lower packing assembly is a direct replacement component designed for use on compatible Impact airless sprayers. It provides a critical seal between the piston rod and cylinder at the lower end of the pump, preventing fluid leakage and maintaining consistent pressure during operation. Replacing worn or damaged packings restores sprayer performance and prevents costly fluid loss and internal component damage.

The Titan 800-355A Lower Packing Assembly is a genuine Titan-manufactured replacement seal kit designed for the lower end of the piston rod in compatible Impact airless sprayers. This assembly creates a high-pressure seal that prevents paint and other fluids from leaking past the piston at the base of the pump during operation, ensuring consistent pressure delivery and efficient spraying performance.
Over time, packings naturally wear due to friction, exposure to solvents, and normal use. Worn lower packings can lead to fluid leakage from the bottom of the pump, pressure fluctuations, reduced spray quality, and potential damage to other internal components. Replacing the lower packing assembly with this genuine Titan component restores proper sealing and extends the life of your Impact sprayer.
| Fluid sealing | Prevents paint and fluids from leaking past the piston rod at the lower pump end |
|---|---|
| Pressure maintenance | Helps maintain consistent fluid pressure for even spray patterns |
| Component protection | Prevents fluid from entering and damaging internal mechanisms |
| Visible leakage | Fluid seeping or dripping from the bottom of the pump housing |
|---|---|
| Pressure loss | Inconsistent pressure or difficulty maintaining desired output |
| Worn or hardened seals | Packings appear cracked, flattened, or have lost flexibility |
| Contaminant buildup | Dried paint or debris preventing proper seal contact |
This Titan 800-355A lower packing assembly is designed for use on the following Impact models. Always confirm fitment using the correct parts diagram for your exact model and revision.

When replacing the lower packing assembly, these associated components are often inspected or replaced to ensure a complete repair.
Inspect for scoring, pitting, or wear that could damage new packings. Replace if necessary.
Often replaced simultaneously with lower packings to ensure complete pump seal integrity.
Check for internal scratches, corrosion, or debris that could affect seal performance.
