Matco-Norca has upgraded its lead-free forged-brass 759 press ball valve to feature leak-prior-to-press technology. This new design incorporates a special EPDM O-ring that allows water or air past the sealing element of any unpressed connection. The valve’s EPDM water O-ring is designed for use with potable water and has the capability to identify any unpressed connection during the pressure-testing process. Available in size 1/2” to 4” and UPC and NSF certified.
