Series KCBGLX - Sizes to 1-1/2” (38.10 mm), Pressures to 20000 (1379 bar)
For extreme conditions of vibration and/or shock in tubing systems, such as an unsupported line near a compressor, coned and-threaded connections are offered with the Autoclave antivibration collet gland assembly. Completely interchangeable with standard Autoclave Engineers medium pressure connections, the collet gland assembly provides equally effective pressure handling capability.
In standard connection systems, the bending stresses on the threaded area of the tubing imposed by excessive vibration or movement may cause premature fatigue failure of the tubing at the back of the thread. By moving the stress concentration back to the unthreaded part of the tubing and providing a wedge-type gripping action, the Autoclave Engineers anti-vibration collet gland assembly strengthens the entire structure. With stress concentration reduced and overall stress level maintained well below the endurance limit of the material, the result is virtually unlimited vibrational fatigue life.
A less complex and more economical design than other vibration-resistant connections, the collet gland assembly utilizes the same coned-and-threaded features of Autoclave medium pressure connections. Series KCBGLX extends the gland nut to provide room for the tapered slotted collet. The design provides a slight difference in angles between the collet and the corresponding taper of the gland nut. As the nut is tightened, it acts to wedge the tapered end of the collet into a gripping engagement with the tubing.
