The patented SPINCLOSER® is a rugged, production-proven machine for closing open tube ends quickly. It produces a 90º flat end closure, which permits maximum utilization of space where many tubes are required within restricted physical dimensions. Copper, brass, aluminum and steel tubes can be closed with the same machine. This is possible due to the unique patented closing process that doesn’t generate heat. Tubes are removed after the closing cycle with the bare hand.
