Assembly Instructions:

  1. Inspect the mating threads for debris or damage. Remove any old fluoropolymer tape or sealant on previously used threads.
    If threads are damaged, use a new adapter before proceeding.
  2. Apply 2 to 3 wraps of fluoropolymer tape or an NSF/FDA approved silicone sealant.
    Do not use Plumbers Putty or Pipe Dope. These chemically react with plastic materials and could cause a failure.
  3. Align ball valve onto mating thread to ensure cross threading does not occur.
  4. Screw ball valve onto mating thread 3 to 5 turns. Do not over-tighten
  5. Pressurize the system and check for leaks.
