Parker A-LOK® tube fittings do not twist
the tubing during installation. 
A-LOK's® ferrule design assures that all make and remake motion is transmitted axially to the tubing. Since no radial movement of the tubing occurs, the tubing is not stressed. The mechanical integrity of the tubing is maintained.

No Distortion
In make-up, there is no undue force in an outward direction to distort the fitting body or ferrules to cause interference between the ferrules and nut. This assures that the nut will back-off freely for disassembly and permits a greater number of easy remakes.

Positive, reliable connections with Parker A-LOK® fittings have been qualified by exhaustive tests and over four decades of experience in the manufacture of quality tube fittings.
Pipe Fittings/Adapters
Parker A-LOK® tube fittings are available in a wide variety of ISO and ANSI pipe thread configurations.
