204 Steel Reducing Couplings


The JCM 204 Steel Reducing Coupling is the simplest means of connecting any combination of two sizes or types of pipe. There is practically no limit to the pipe sizes that can be connected – either to reduce or increase in size.

One common use is joining large steel pipe to ductile iron or C-905 PVC pipe. Listed are the most common sizes. Other sizes are available upon request.
