Premium -50°F Antifreeze, 275-Gallon Bulk Tote

Star Brite Premium -50°F Antifreeze, 275-Gallon Bulk Tote

Cover both water systems and marine engines with a single antifreeze instead of stocking two. This 275-gallon tote of Star Brite's Premium -50°F Antifreeze is a ready-to-use propylene glycol formula built for potable water systems and marine engine winterization alike, giving boatyards, marinas, RV dealerships, and service departments a single bulk supply for a full season of winterizing.

The corrosion-inhibitor package helps protect against rust and buildup while the formula provides freeze and burst protection down to -50°F, keeping pipes, tanks, and engine cooling systems intact through winter storage. It's compatible with copper, brass, and plastic plumbing, making it suitable for RVs, boats, campers, home plumbing, and other seasonal water systems. Since it's ready to use straight from the tote, crews can move from job to job without measuring or diluting.

How to Winterize Water Systems

Drain the water tank and as much water as possible from the system by opening the hot and cold faucets and all other outlets, then use air pressure to blow out any remaining water. Drain the water heater tank, then bypass it by disconnecting the inlet and outlet lines and connecting them together.
