Part 805-505 is a replacement seal retainer used in the fluid section of compatible spray equipment. This component holds seals and packings in position, maintaining proper compression and alignment. When the original retainer becomes worn, corroded, or damaged, replacement restores proper seal function and prevents fluid leaks.

The 805-505 seal retainer is a direct replacement component for Iimpact 840 I and IA, impact 740, Impact 740-840, and Impact 840 service spray equipment. This precision-machined component is installed in the fluid section where it holds seals, packings, and o-rings in their proper positions. By maintaining correct compression and alignment of sealing elements, the retainer ensures effective sealing against fluid pressure and prevents leaks. A worn, corroded, or damaged retainer can allow seals to shift or extrude, leading to fluid bypass, pressure loss, and external leaks. It may also cause uneven seal wear, reducing service life. This replacement retainer is manufactured to exact specifications for proper fit and surface finish. The material is selected for compatibility with common coatings and cleaning solvents. Installation requires careful cleaning of the seal cavity and proper positioning of new seals before securing the retainer. Regular inspection during pump service helps identify retainer damage before it affects seal performance.
