Brake Chamber Diaphragms
Heavy-duty rubber diaphragms for Type 30, Type 24, and Type 20 brake chambers. High temperature resistant.
Overview
Premium Rubber Brake Diaphragms
The diaphragm is the most critical internal component of an air brake chamber, responsible for expanding under air pressure to actuate the pushrod. BRC diaphragms are manufactured using a proprietary nylon-reinforced EPDM (Ethylene Propylene Diene Monomer) rubber compound, designed to withstand extreme temperature fluctuations from -40°F to 200°F.
Available in all standard sizes including Type 30, 24, 20, and 16, our diaphragms offer superior flex-fatigue resistance, ensuring hundreds of thousands of actuation cycles without cracking or leaking. Perfect for fleet rebuilding programs and wholesale distributors.
