Installation Steps
• Step 1 - After cutting and deburring tube, clean tube surface with an alcohol wipe.
• Step 2 - Mark tube to depth of insertion plus ½”.• Step 3 - Place a small ribbon of adhesive around
the tube and, above 1”, inside the fitting.• Step 4 - Push fitting on the tube, making a ¼-turn
motion, forcing a bead of excess adhesive out of the joint.
• Step 5 - Position fitting as needed. Then, allow joint to cure prior to pressure testing.
