Master valve activates by a "relieving" type on/off valve. Designed for install on a manual shut-off (#49-90) for source of air and water.

Product Features:

  • The E-Z view filter canister allows the filter element to been seen without disassembling.
  • Use with either 1/8" or 1/4" tubing.
  • Valve plumbs into the main air and water lines coming into the operatory.
  • Includes barbs, tubing clamps, and gaskets.
  • Compatible with A-dec units.

Instructions (PDF):

  1. Turn off the main supply of air and water.
  2. Unscrew the compression nut from the manual shut-off, making sure to keep the copper or plastic compression fitting within the nut.
  3. Slide the 3/8" nipple fitting into the nut through the sleeve and position into the manual shut-off.
  4. Finally slide the nut & sleeve onto the threads of the manual shut-off & tighten. The compression fitting should clamp down on the nipple fitting, holding it in place.
  5. If the master on/off valve is loose in the manual shut-off or leaks from around the nut, then remove and wrap a few layers of teflon plumbers tape around the nipple and reinstall. Continue until valve has a snug, leak-free fit.

Replacement Parts:
Filter element (#50-57)
E-Z View Canister (#AK-58)
Canister base o-ring (#18-OR-020)

Works Great

My operatory water was spitting and had uneven water flow, seems my old master on/off was leaking air from the switch into the waterline.
Easy replacement and it is fixed!
