TYLOK® CBC-Lok® DMC-STB Series SS-12-DMC-12-STB Straight Thread Boss Connector, 3/4 in Tube x 1-1/16 in MNPT

CBC-Lok® tube fittings are comprised of four components - body, front ferrule, rear ferrule and nut. A leak-proof seal is obtained through proper ferrule action as the ferrules are tightened onto the tubing via axial thrust provided by the nut. The front ferrule provides the leak-proof seal, when the nut and ferrules are properly drawn up the specified number of turns. The rear ferrule grips the tubing preventing pull-off. The stainless steel nuts are silver plated and dry film lubricant is applied, reducing torque and ensuring proper sealing.
