Click-N-Seal connection fittings prevent over-tightening to eliminate leaky connections in apparatuses such as intravenous-drip equipment. When the correct torque is reached, the installer can feel and hear a click and the fitting cannot tighten beyond that point. Fittings can thereby be hand tightened without tools or guesswork.
