The Midland Haldex GC3030R is a GoldSeal+ combination spring brake chamber in Size 3030, designed to fit all drum brake applications. It delivers a 2.50-inch (64mm) standard stroke with a maximum air pressure rating of 150 psi. The service housing is fabricated from 9-gauge steel with an advanced powder coat finish for corrosion resistance. A double O-ring centerseal and plastic bearings provide long-term sealing integrity. The diaphragm uses a high-quality rubber compound rated for flexibility down to -40°F. Mounting studs are 5/8-11 UNC Grade 5, 1.50 in. long, with a 5/8-18 UNF pushrod thread and 3/8-18 NPTF air port threads. Available from Pro Gear and Transmission.
