Type 30 Diaphragm Only

Type 30 Diaphragm Only

This is a replacement rubber diaphragm for a standard Type 30 air brake chamber, commonly found on heavy-duty commercial vehicles, including concrete mixers. The diaphragm is a critical component that seals the air chamber, allowing air pressure to actuate the brake rod. This part is needed for routine maintenance or when the original diaphragm fails, which can cause air leaks and a loss of braking force. This diaphragm is designed for a standard 2.50-inch stroke and has a diameter of approximately 7.88 inches.
