Titan 800-355A Lower Packing Assembly for Impact and Advantage Sprayers
Titan 800-355A is an OEM lower packing assembly designed for the lower end of the piston rod in compatible Titan Impact and Advantage 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. It is listed in the official Titan Impact 1040T owner's manual as "Lower packing" and is also cross-referenced under Titan part number 0552178.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan 800-355A lower packing assembly. Listed in the official Titan Impact 1040T owner's manual as "Lower packing" [citation:5][citation:13]. Also cross-referenced as Titan 0552178 [citation:4][citation:9]. Genuine Titan-manufactured seal kit for the lower end of the piston rod. |
| Function | Creates a high-pressure seal between the piston rod and cylinder at the lower end of the pump. Prevents paint and fluids from leaking past the piston during operation. Maintains consistent fluid pressure for even spray patterns. Protects internal mechanisms from fluid contamination. |
| Compatible Titan Models | Impact 1040, Impact 1040TS, Impact 1140I, Impact 1140IX; Advantage 700 (Lowboy), Advantage 1100 (Lowboy); 840I, 840IX; EPX2455, EPX2555 [citation:2][citation:10]. Verify fitment against your specific model parts diagram before ordering. |
| Common Failure Symptoms | Visible fluid leaking from the bottom of the pump housing. Pressure drops or difficulty maintaining desired output. Erratic or inconsistent spray patterns. Packings appear cracked, flattened, or have lost flexibility. Dried paint or debris preventing proper seal contact. |
| Service Guidance | Always relieve system pressure before servicing. Disassemble the pump to access the piston rod. Remove old packings, clean sealing surfaces thoroughly, lubricate new packings with compatible fluid, and install in the correct orientation. Inspect the piston rod for scoring or wear before installing new packings. Refer to the service manual for detailed step-by-step instructions and torque specifications. |
| Related Parts Serviced Together | Piston rod (inspect for scoring, pitting, or wear), upper packing assembly (often replaced simultaneously for complete seal integrity), pump cylinder/housing (check for internal scratches or corrosion), and repacking kits for complete fluid section service. |
| OEM & Brand Information | Genuine Titan component manufactured to original specifications for proper fit and reliable performance in compatible sprayer systems. |
| Commercial Benefits | Restores proper lower packing seal, eliminates fluid leakage, recovers consistent pressure and spray quality, and extends the service life of the pump fluid section. |
The 800-355A Lower Packing Assembly is a practical replacement for contractors and service technicians maintaining compatible Titan Impact and Advantage sprayers. If you notice fluid leaking from the bottom of the pump, pressure drops during operation, or material seeping around the piston rod at the lower end, the lower packing is likely worn and needs replacement. This OEM assembly restores proper sealing and extends the life of your sprayer. When replacing the lower packing, always inspect the piston rod for scoring or wear, and consider replacing the upper packing simultaneously for complete pump seal integrity. Follow the service manual for your specific model regarding packing orientation and torque specifications.
