These new crimpers squeeze the copper rings used on brass fitting PEX systems for radiant heating, snow melt systems, or potable waterlines. The design of the crimpers does not leave tool marks or distort the rings, states the manufacturer. Each crimper comes with a go/no-go gauge and an Allen wrench. Four sizes are available.
