The NIBCO Press System pecent is user friendly, quick and easy to install. The pressing tool assures a consistent, reliable, safe and clean connection with no flame, solder or flux. The lightweight, ergonomically designed press tool features a pressing head that smoothly rotates 350 degrees making it ideal for working in tight spaces. As a safety feature, an interruptible crimp cycle will instantly stop the forward motion of the rollers when the trigger is released. A manual retract switch allows the user to return the rollers to the starting position in case of error or emergency. When properly crimped, a unique ''N'' witness mark is clearly visible.
