    Johnsen’s 5100 Heavy Duty Air Brake Anti-Freeze, 1 Quart

    Part #: JO-5100

    Johnsen’s 5100 Heavy Duty Air Brake Anti-Freeze is a methanol-based air brake and air system antifreeze and dryer concentrate packed in a 1-quart format. It is engineered to remove moisture and dissolve ice deposits on contact, helping to prevent freezing and corrosion in air brake lines, valves, tanks, and related pneumatic systems year-round—even under subzero conditions.
