Tucson manufactures accessories such as sub-plates, manifold blocks, gear couplings, minimess check valves along with hoses. We also custom make manifold blocks for specific applications as per requirement. Our sub-Plates and manifolds are made from high grade cast iron. Castings are checked for being close grained with specific composition and having the requisite strength. All the ports on the blocks are counter bored and the contact surfaces machined to Tucson’s high Quality Standards.
