Upper Pressure Ring for Spraytech EP Series Airless Sprayers
The Spraytech 0294326 Upper Pressure Ring is an OEM replacement component used in the pump fluid section of EP2300, EP2400, and EP2510 airless sprayers. It sits above the seal stack or packing set, distributing compressive force evenly to the seals and maintaining correct preload. This ensures consistent sealing against the piston rod and cylinder wall.
Over time, the upper pressure ring can become worn, cracked, or deformed due to repeated pressure cycles, chemical attack, or improper assembly. A damaged ring can cause uneven seal compression, leading to premature packing failure, pressure loss, fluid bypass, and external leaks. Replacing it with the 0294326 restores proper seal loading and pump performance.
What it does and when to replace it
| Seal compression | Distributes retainer nut force evenly across the packing stack |
|---|---|
| Pressure integrity | Helps maintain consistent sealing against the piston rod |
| Prevents bypass | Reduces fluid leakage past the packings |
| Cracked or broken | Visible fracture, especially near the inner or outer edge |
|---|---|
| Warped / dished | Ring no longer sits flat; causes uneven seal loading |
| Corrosion or pitting | Surface damage from paint or solvent exposure |
| Rebuilding pump | Preventative replacement during major overhaul |
