Metal Made Industrial Coupling is designed for use with our glass process plant and pipeline components are of major importance from two main points of view. The Coupling is made using cast iron and can be supplied with epoxy painting or powder coated in improves resistance to corrosion. The Coupling has flat buttress ends. The Coupling has the feature that for glass plants installed in relatively corrosive environments, the added advantage is the availability of couplings constructed forms various materials including stainless steel and plastic.
