SprayTech part 0294523 is a lower pressure ring used in the fluid section of the SprayTech Airless EP2510 sprayer. This precision ring works in conjunction with the V‑ring and lower ring support to maintain proper seal compression and prevent fluid bypass. Replacing a worn or distorted lower pressure ring helps restore consistent pressure and extends seal life.

Components: This is a single lower pressure ring; no additional parts are included.
The SprayTech 0294523 lower pressure ring is a key sealing component within the fluid section of the SprayTech Airless EP2510 airless paint sprayer. It works together with the V‑ring and lower ring support to create a reliable dynamic seal around the piston rod, preventing fluid bypass and maintaining consistent operating pressure.
Over time, constant pressure cycling, chemical exposure, and normal wear can cause the lower pressure ring to become hardened, cracked, or distorted. A compromised ring can lead to insufficient seal compression, resulting in pressure loss, erratic spray, or leakage past the V‑ring. Replacing the ring with OEM part 0294523 restores the proper sealing geometry and helps extend the life of the entire seal stack.
| Seal compression | Applies controlled pressure to the V‑ring stack to ensure a tight dynamic seal |
|---|---|
| Fluid containment | Helps prevent paint from bypassing the V‑ring and leaking into the lower pump housing |
| Pressure stability | Maintains consistent sealing force for steady output pressure |
| Visible damage | Cracks, warping, or flattening of the ring surface |
|---|---|
| Pressure loss | Sprayer struggles to maintain pressure even after replacing the V‑ring |
| Recurring leaks | Fluid bypass continues despite new seals, indicating ring deformation |
| During rebuild | Replace whenever the fluid section is disassembled for service |
SprayTech part 0294523 is designed specifically for the fluid section of the SprayTech Airless EP2510 sprayer. Always verify fitment using your machine's parts diagram, especially if you have an older revision or a model variant.

The lower pressure ring works in conjunction with several other fluid section components. For a reliable repair, inspect or replace these related parts as a set.
The V‑ring sits directly against the lower pressure ring; a worn ring can prevent proper V‑ring compression.
The lower ring support provides a rigid base for the pressure ring and V‑ring assembly; replace as a set.
Upper packings work with the lower seals to create a complete fluid‑tight barrier; replace together.
