The Association of American Railroads recently approved Midland Manufacturing’s new breather vent for hydrogen peroxide applications.

Part of Midland’s line of tank car valves and fittings, the breather vent features a component check valve in the cap that’s designed to prevent hydrogen peroxide from leaking if a tank car derails or turns over because of an accident. In addition, the vent features a stone filter instead of membrane filters to improve wear characteristics and chemical resistance.

Midland also offers a kit that fits three existing breather vent body styles and can be retrofitted in the field.

A division of the OPW Fluid Transfer Group, Midland provides tank car safety valves and equipment.
