Part number 2370116 is a genuine rubber sleeve used in Elite 5500 and PowrLiner 4500/5500 airless sprayers. This flexible rubber component serves as a vibration dampener, protective cover, or sealing element between moving parts or housing sections. It helps reduce noise, absorb shock, and prevent contamination from entering critical areas of the sprayer. A cracked, torn, or deteriorated rubber sleeve can lead to increased vibration, noise, or exposure of internal components to debris. This genuine replacement restores proper dampening and protection.

The 2370116 Rubber Sleeve is a genuine OEM component designed for Elite 5500 and PowrLiner 4500/5500 airless sprayers. This flexible rubber component is engineered to provide critical functions such as vibration dampening, shock absorption, and protection of internal mechanisms from dust, debris, and moisture.
In airless sprayers, rubber sleeves are often positioned between moving parts, around drive shafts, or at connection points to reduce noise and prevent metal‑to‑metal contact. They also serve as barriers that seal out contaminants that could cause premature wear or failure of precision components. The rubber material is formulated to resist oil, solvents, and temperature extremes commonly encountered in sprayer operation.
Over time, rubber can become brittle, crack, or lose its elasticity due to exposure to chemicals, heat, and ozone. A deteriorated sleeve may no longer provide adequate dampening, leading to increased vibration and noise, or may fail to seal properly, allowing debris to enter sensitive areas. Replacing a worn rubber sleeve with this genuine part restores quiet operation and protects internal components.
| Vibration dampening | Absorbs and reduces vibration from moving parts |
|---|---|
| Noise reduction | Minimizes operational noise by isolating components |
| Contamination barrier | Prevents dust, debris, and moisture from entering critical areas |
| Shock absorption | Cushions impacts and reduces stress on components |
| Visible cracking / tearing | Sleeve shows cracks, splits, or tears in the rubber |
|---|---|
| Hardening / loss of elasticity | Rubber feels stiff and no longer flexible |
| Increased vibration / noise | Noticeable increase in sprayer vibration or operating noise |
| During disassembly | Always replace rubber sleeves when surrounding components are serviced |
Part 2370116 is designed for the following sprayer models. Always verify your machine's parts diagram to confirm correct fitment.

| PowrLiner 4500 | Rubber Sleeve |
| PowrLiner 5500 | Rubber Sleeve |
When replacing the rubber sleeve, it's good practice to inspect these related components, as they may be affected by wear or deterioration.
Other rubber components in the same area may also be aged. Inspect and replace if hardened or cracked.
Check for wear or damage on shafts that contact the sleeve. Rough surfaces can accelerate sleeve wear.
Ensure mating housings or covers are properly aligned to prevent pinching or uneven wear of the new sleeve.
