- Slide the Flangeless SealTight™ nut and ferrule, in that order, at least 3/16" from the end of your flat-cut, burr-free tubing. The slit in the ferrule should face the nut, with the flat surface of the ferrule towards the
port.
Please Note: The Flangeless SealTight nut and ferrule must be used exclusively with each other.
- Insert the assembly into the receiving port, pushing the tubing into the port until it bottoms out.
- Finger tighten the nut until snug, while continuing to hold the tubing against the bottom of the port.
