PowrLiner part 341347 is a seal designed for use in compatible PowrLiner and Elite sprayers. This critical component prevents fluid leakage, maintains system pressure, and protects internal components from contamination. Replacing a worn, hardened, or damaged seal restores proper sealing integrity, eliminates leaks, and ensures reliable spray performance.

The PowrLiner 341347 Seal is a genuine OEM component used in the fluid section, valve assemblies, or other critical areas of compatible PowrLiner and Elite sprayers. Its precise design ensures a leak‑tight fit, preventing material bypass, maintaining consistent pressure, and protecting internal components from contamination.
Over time, seals can harden, crack, or wear due to exposure to solvents, abrasives, and normal operating cycles. A failed seal leads to fluid leaks, pressure loss, erratic spray patterns, and potential damage to adjacent components. Replacing with the correct 341347 seal restores system integrity and ensures reliable, efficient spraying.
| Prevents leakage | Stops fluid from escaping the pump or valve assembly |
|---|---|
| Maintains pressure | Ensures consistent system pressure for proper spraying |
| Protects components | Keeps contaminants out of sensitive internal parts |
| Hardened / brittle | Seal has lost flexibility, cannot conform to mating surfaces |
|---|---|
| Cracked / torn | Visible damage that compromises sealing ability |
| Worn / flattened | Loss of material leads to leaks and pressure drop |
| Fluid leaks | Visible leakage from the seal area during operation |
PowrLiner part 341347 is compatible with the following sprayer models. Always confirm fitment using the correct parts diagram for your exact model and serial number.

When replacing a seal, it is typical to inspect or replace other fluid section components to ensure complete restoration of performance.
Inspect the piston or plunger surface for scoring or wear that could damage the new seal.
Check the sealing surface for corrosion, nicks, or scratches.
Replace any backup rings or retainers that support the seal.
