Titan 805-505 Seal Retainer
Maintain the proper positioning of your sprayer's sealing components with the Titan 805-505 Seal Retainer. This genuine Titan replacement part is designed to retain the specified seal within its designated assembly. It provides a targeted repair option when the original retainer is worn, damaged, missing, or no longer suitable for reuse.
Repair Application: Replacement of a damaged, missing, or unsuitable seal retainer.
Service Considerations: Inspect the mating seal, retaining surfaces, and adjacent components.
Fitment: Confirm using the machine's official Titan parts diagram.
Ordering Note: Part number 805-505 identifies the seal retainer only. Do not assume that a seal, fasteners, or other assembly components are included unless the product packaging specifically states otherwise.
Secure the Correct Sealing Arrangement in Your Titan Pump
The Titan 805-505 Seal Retainer is a manufacturer-listed fluid-section component for compatible Titan Impact airless sprayers. Located at the upper end of the fluid-section assembly, it supports the designated seal-retention arrangement. Replacing a damaged or missing retainer helps restore the correct mechanical configuration during pump servicing.

For Impact 840I, 840IA or other machine variants, confirm the exact fluid-section assembly and part number before purchase.
What Does the Titan 805-505 Seal Retainer Do?
The seal retainer forms part of the fluid section's mechanical retaining arrangement. It helps maintain the specified position of the associated sealing components within the pump assembly.
During operation, fluid-section packings and related components must remain properly positioned while the piston moves through the pump. Correctly installed retaining components support this assembly arrangement.
A damaged retainer should be evaluated together with the adjacent nut, spacer, packing assembly and housing. Replacing the retainer alone will not correct worn packings, damaged piston rods or defective check valves.
Common Problems & Inspection Points
Bent or Distorted Retainer: Inspect for deformation that prevents proper assembly.
Worn Contact Surfaces: Check for damage where the retainer interfaces with adjacent parts.
Corrosion or Physical Damage: Evaluate whether the part remains suitable for reuse.
Incorrect Assembly: Verify the installation order and orientation of the retaining and packing components.
Fluid Leakage: Inspect the entire sealing arrangement; leakage is not proof that the retainer itself is defective.
Seal Retainer Inspection & Replacement
1. Prepare the sprayer: Disconnect power and complete the manufacturer's pressure-relief procedure.
2. Access the fluid section: Follow the applicable Titan service manual to expose the retaining and packing components.
3. Inspect related components: Examine the knock-off nut, spacer, upper packing and upper housing for wear or damage.
4. Replace the retainer: Install part 805-505 in its specified position using the factory assembly sequence.
5. Reassemble correctly: Observe the manufacturer's packing orientation, lubrication and fastening instructions.
6. Test for proper operation: Prime the sprayer and inspect the fluid section for leakage and correct pressure performance.
