Matco-Norca 759 Press Ball Valve
September 21, 2017
The lead-free forged brass 759 Press Ball Valve features leak-prior-to-press technology and incorporates an EPDM O-ring that will allow water or air past the sealing element of any un-pressed connection. The systems offer the advantage of flame free installations. Not only does the press-fit system make the job site safer by eliminating the risk of fire, it also lends itself to greater productivity and reduced labor costs. The product is available in sizes ½ inch to 4 inches.
