The Powr 107-060 Seal Washer is a precision‑formed washer used in the pump assembly of many PowrTwin, PowrLiner, and PowrBeast sprayers. It creates a reliable seal between two mating surfaces – typically between the fluid section and the crankcase or within the valve stack. This washer prevents fluid leaks, maintains internal pressure, and protects against contamination.
Over time, seal washers can become compressed, cracked, or brittle due to heat, chemical exposure, or normal wear. A failed washer allows fluid to escape, leading to external leaks, loss of pressure, and potential damage to surrounding components. Replacing the seal washer restores leak‑free operation, ensures consistent pressure, and prevents costly damage from fluid ingress.
| Fluid sealing | Prevents leakage between pump sections or at valve interfaces |
|---|---|
| Pressure containment | Helps maintain internal pressure by creating a leak‑tight barrier |
| Contamination prevention | Blocks entry of debris or moisture into critical areas |
| Visible cracks / compression set | Washer is flattened, cracked, or no longer resilient |
|---|---|
| External leakage | Fluid seeping from between pump sections |
| During pump overhaul | Always replace seal washers when rebuilding the pump |
| After chemical exposure | Replace if washer shows signs of chemical attack |
