Unlike other saliva ejectors that rely on friction to hold the tip in place, SecureTip saliva ejectors screw securely into the valve – resulting in an ejector that functions as a single bonded piece. This prevents slips, drops, and the need to replace ORings – which saves both time and money. Features and Benefits: Saliva ejector screws into corresponding adapter for a secure fit and no more dislodging of saliva ejector during patient treatment! No more changing of O-Rings or Rubber Tips.
