Assembly Instructions
1. Cut tube squarely and cleanly removing all burrs.
2. Grasp ftting. Do not remove nut.
3. Insert tube in ftting through nut until tube seats frmly against tube
shoulder in body.
4. Grip tube frmly to prevent turning and tighten nut to fnger-tight.
Continue to tighten nut for one and three-quarter additional turns
(one and one-half turns for 1/2" size tube fttings) for a positive,
leak proof seal. During tightening a slight “give” will be felt. This
“give” indicates the sleeve has been sheared from the nut. It is not
necessary to tighten the nut all the way down.
To Reconnect:
1. Reinsert tubing
2. Tighten nut one-eighth of a turn more than previous make-up.
