Part number 800-253 is a Housing Slider Bushing used in the drive housing assembly of compatible airless sprayers. This bushing supports the sliding piston or rod, reducing friction and wear during operation. Replacing a worn or damaged slider bushing restores smooth pump movement and helps prevent premature wear to the housing and piston.

The 800-253 Housing Slider Bushing is a critical wear component installed in the drive housing of compatible airless sprayers. It acts as a bearing surface for the sliding piston or connecting rod that drives the pump. Made from durable, low‑friction material, this bushing ensures smooth reciprocating motion and maintains proper alignment of internal components.
Over time, the bushing can wear due to continuous operation, contamination, or inadequate lubrication. A worn bushing may cause excessive play, increased friction, and accelerated wear of the piston or housing bore. Replacing the slider bushing restores smooth operation and extends the life of the drive system.
| Friction reduction | Provides a low‑friction surface for the sliding piston or rod |
|---|---|
| Alignment | Helps maintain correct alignment of moving parts within the drive housing |
| Wear protection | Prevents metal‑to‑metal contact, protecting both the piston and housing bore |
| Excessive play | Noticeable side‑to‑side movement of the piston/rod indicates bushing wear |
|---|---|
| Increased vibration | Rough operation or knocking sounds from the drive housing |
| Visible wear/damage | Scoring, cracking, or deformation of the bushing upon inspection |
| Fluid leakage | Oil or grease leaking past the bushing due to wear |

When servicing the housing slider bushing, these components are often inspected or replaced at the same time to ensure complete drive system reliability.
Inspect for scoring or wear; a damaged piston will quickly ruin a new bushing.
Worn seals can allow contamination into the bushing area; replace if leaking.
Fresh, clean lubricant is essential for proper bushing performance and longevity.
