JB Industries Pump Guard is a 16 oz antifreeze and lubricant formulated to protect pressure washer pumps during storage or winterization. It coats and safeguards internal components, preventing freezing down to -25°F as well as corrosion and cracking.

This professional-grade pump winterizer fluid lubricates pistons, seals, and valves, preventing rust and mineral deposits from forming inside the pump. By conditioning all the pump's internal parts, it helps maintain optimal performance and extend the life of your pressure washer.

Pump Guard is universally compatible with all gas or electric pressure washers, making it suitable for any brand – perfect for both home use and commercial equipment. It's easy to apply through the pump's water inlet following standard winterizing steps, preparing your unit in minutes for safe long-term storage with no special tools required.

Each 16 oz bottle provides multiple treatments. You can winterize several machines or protect one pressure washer across multiple seasons with a single bottle. This high-value size offers more protection per ounce than single-use 4 oz alternatives, saving you time and money on pump maintenance.
