Overview
STA-BIL's Pump Protector, model 22007, is a 4 ounce can of antifreeze and lubricant foam made to coat a pressure washer pump's pistons and seals before storage.
It targets a specific failure: a pump that leaks or cracks in spring because seals dried out or trapped water froze over winter. This is a storage accessory for the pump itself, not a general engine or fuel additive.
- Connects via a hose to the pump inlet
- Combines antifreeze and lubricant in one foam
- Dispense until fluid appears at the outlet
- Stays usable up to 2 years once opened
Who it's for
For anyone storing a gas or electric pressure washer for winter or an extended stretch. Not relevant if the issue is fuel system storage rather than the pump.
Strengths and trade-offs
Drawn from this product's published specifications.
- Quick hose-and-button application at the pump inlet
- Combines antifreeze and lubricant in one product
- Usable up to 2 years once opened
- Single small can, unclear how many pumps it treats
- Addresses the pump only, not fuel or the engine
Performance notes
The hose on the can connects to the pump inlet; lifting the cap and pressing the button pushes protective foam through the pump until it appears at the outlet, at which point the internals are coated. STA-BIL states an opened can stays usable for up to 2 years if the open date is marked on the package.
