Autoclave KCBGLX40-316MC Anti-Vibration Collet Gland Assembly
Medium Pressure “Slimline SF” Cone & Thread, Pressures to 20,000 psi
Principle of Operation:
Parker Autoclave Engineers Medium Pressure Cone and Thread connections were created for those applications that require higher flow rate capability. Designed for a maximum of 20,000 psi MAWP using high tensile strength cold worked 316 Stainless Steel material as standard. In addition, we offer even larger ID tubing de-rated to 15,000 psi for maximum flow rate capability. This Medium Pressure series has all the benefits of the High-Pressure version with all metal sealing, sizes ranging from 1/4″ to 1-1/2″ and temperature ranges from -423F to +1200F.
Fittings and tubing found in this section are designed using ASME B31.3 Chapter IX standards to be compatible with our 15SM & 20SM, 20DBNV, 20DV Needle Valves, and all of our various ball valve configurations including Subsea. There is a Parker Instrumentation fitting for just about any application of fluids under extreme pressure and/or temperature condition.

Series KCBGLX:
For extreme conditions of vibration and/or shock in tubing systems, such as an unsupported line near a compressor, Parker Autoclave Engineers offers the anti-vibration collet gland assembly. Originally patented in 1968, this assembly is completely interchangeable with standard Parker Autoclave Engineers Medium Pressure gland connections and 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 Parker Autoclave Engineers anti-vibration collet gland assembly strengthens the entire structure while preventing rotation. 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 Parker Autoclave Engineers 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.
Material:
316 SS with bonded dry film molybdenum disulfide to help prevent galling. Additional thread lubricant not needed.
