It stores compressed air from the compressor for reliable brake actuation and operation of air-powered accessories. The steel tank is welded, pressure-tested, and coated inside and out for corrosion resistance, with mounting brackets and multiple threaded ports for air lines and a drain. Replace your tank if it shows rust-through, pinhole leaks, or damage that causes pressure loss, as a faulty reservoir can compromise braking safety.
