EZ-Joint works as follows. A tube is inserted into the fitting, it passes Jaw Holder, stainless steel Jaws, Spring, and then through two O-Rings until it reaches to Tube stop. Jaw with four teeth opens out in sliding the tube in, while it grabs onto the tube when the tube reaches to the Tube Stop. Two O-rings compress between the wall of the fitting and the tube, which prevent leakage. O-Ring1 first block leakage and O-Ring2 also block any possible leakage. As the tube reaches to the tube stop and JAW press down to the surface of the tube and grab the tube. When fluid starts to run through in the tube, pressure comes from inside of the fitting to outside. The pressure pushes Spring back through the two O-Rings, which press down Jaws and ultimately increase the grabbing power of Jaws. The stronger the pressure is, the more grabbing power Jaws generates. If push Jaw Holder forward, Jaw is pushed up to the space between the wall of the fitting and Jaw Holder and open up the teeth. It releases the tube. CopyRight ⓒ2005 www.jointop.co.kr All Rights Reserverd.
