Installation Guide

• Insert the Tube Fittings Assembly and tighten the nut as per assembly instruction provide in this catalogue in section of Installation Instructions (1.1/4 turn form- tight) and the joint is ready to take any kind of pressures from low to high.
• The front ferrule, as it is urged forward against the tapered area of the body is forced inward gripping and subsequently sealing the leading edge tightly onto tubing.
• Simultaneously the back. Ferrule , done tailed directly behind the front ferrule, swages beneath its trailing edge affording the desired “coining” action and mechanical connection of tubing and fitting.
• It is this interaction of ferrules that allows NU-LOK too achieves its excellent sealing capabilities under a wide variety of application variables.
