SprayTech part 0294522 is a lower ring support used in the fluid section of the SprayTech Airless EP2510 sprayer. This structural component supports and aligns the lower seal stack and V‑ring assembly, ensuring proper sealing geometry and piston rod alignment. Replacing a worn or damaged lower ring support helps restore correct seal positioning and prevents premature seal failure.

Components: This is a single lower ring support; no additional parts are included.
The SprayTech 0294522 lower ring support is a precision component within the fluid section of the SprayTech Airless EP2510 airless paint sprayer. It serves as the base support for the V‑ring seal stack, ensuring correct alignment and compression of the seals around the reciprocating piston rod.
Over time, repeated pressure cycling, chemical exposure, or improper disassembly can cause the lower ring support to become deformed, cracked, or corroded. A compromised support can lead to misalignment of the V‑ring, resulting in premature seal wear, fluid leakage, and pressure instability. Replacing the support with OEM part 0294522 restores the structural integrity of the seal stack and extends the life of the sealing components.
| Seal alignment | Provides a flat, rigid base for the V‑ring stack to ensure concentric sealing around the piston rod |
|---|---|
| Compression control | Helps maintain correct compression on the seals for leak‑free operation |
| Structural integrity | Prevents distortion of the seal assembly under high operating pressures |
| Visible damage | Cracks, warping, or corrosion on the support surface |
|---|---|
| Recurring seal leaks | New V‑rings leak prematurely, indicating possible support misalignment |
| Piston rod wear | Uneven wear on the rod suggests the support may be allowing misalignment |
| During fluid section rebuild | Best practice is to replace the support whenever the seal stack is serviced |
SprayTech part 0294522 is designed for the fluid section of the SprayTech Airless EP2510 sprayer. Verify fitment with your machine's parts diagram, as revision changes may affect component compatibility.

The lower ring support works in conjunction with several other fluid section components. When servicing one, it's wise to inspect or replace the related parts.
The V‑ring sits directly on the lower ring support. A damaged support will cause premature V‑ring failure.
Upper packings and seals work with the V‑ring to form a complete fluid‑tight barrier; replace as a set.
A worn or scored rod can damage the support and seals; inspect carefully during service.
