Piping is more efficient than hose for dust collection over long distances. This clear plastic piping comes in 36" lengths to help get your dust collection from point A to point B. Shown here using 2-1/2'' plastic hangers for mounting. Use 2-1/2'' dust hose or 2-1/2'' coupler to join lengths of pipe, or to connect pipe to other 2-1/2" fittings. Caution: Be sure to ground your dust collection system, especially when using plastic components over long distances.
