The SprayTech 02305 O‑Ring is a genuine OEM replacement seal used in critical fluid passages of compatible SprayTech Airless sprayers. It creates a leak‑tight seal between components such as the fluid manifold, pressure transducer, pump housing, or filter assembly. Proper sealing is essential for maintaining consistent operating pressure and preventing costly fluid leaks.
Over time, O‑rings can become brittle, flattened, or cracked due to exposure to solvents, coatings, heat, and normal wear. A failing O‑ring may cause visible fluid seepage, pressure loss, erratic spray, or air ingestion into the system. Replacing worn seals with genuine SprayTech parts restores integrity and ensures reliable performance.
| Prevents fluid leaks | Seals connections to stop paint or solvent from escaping |
|---|---|
| Maintains pressure | Ensures the system retains proper operating pressure |
| Prevents air ingestion | Blocks air from entering the fluid path, maintaining prime |
| Visible leakage | Fluid seeping from connections or around the seal area |
|---|---|
| Hardened / brittle | O‑ring feels stiff, cracked, or no longer pliable |
| Flattened or nicked | O‑ring has lost its round profile or shows surface damage |
| During component service | Always install new O‑rings when disassembling sealed connections |
Part 02305 is compatible with the following SprayTech Airless sprayers. Always verify fitment using the correct parts diagram for your exact model and serial number.
| Model | Component Application |
|---|---|
| SprayTech Airless EP2300 SE | Various sealing locations |

When replacing O‑rings, it is common to inspect and replace associated seals and components at the same time.
If one O‑ring has failed, others in the same fluid path may also be worn.
The filter housing often contains O‑rings; inspect and replace as needed.
For persistent leaks, consider a full pump packing kit for a complete seal refresh.
