The LF3800 fitting has an integral gripping collet, washer and o-ring. The collet is used to hold the tubing in place and the viton o-ring seals the connection on the outside diameter (O.D.) of the tubing. The collet has six areas which bite into the tubing, called gripping teeth. The collet bites onto the tubing when positive pressure is applied or if the tube is being pulled.

The body of the fitting is formed after the collet, washer and o-ring are installed in the stainless steel housing.

LF3800 fittings also contain a stainless steel washer. The washer separates the viton o-ring from the collet, protecting it at the same time. The o-ring is captive under the washer by virtue of the swaging action when the body is formed. The presence of this washer leaves a small amount of compression on the o-ring even in its static state, ensuring a quality seal for a wide range of pressures. To release the tubing from the fitting, depress the collet before pulling the tube out of the fitting. When you press down on the collet you are keeping the collet locking slope away from the integral angle of the body.
