The SV-9 Saddle Valve is the original self-piercing, patented C-frame construction that's been a time saver to installers for many years. It fits 3/8" - 5/8" tubing, and uses a 1/4" or take-off compression nut.
Note: This saddle valve contains more than 0.25% lead and is illegal to use in any plumbing system providing water for human consumption anywhere in the United States.
