What are the characteristics of VCR connectors?

VCR connector is a type of face sealed connector, which uses precision manufactured metal gaskets as sealing elements and has high-purity metal to metal sealing. So, do you know the characteristics of VCR connectors? 
 

The characteristics of VCR connectors are as follows: 
 

VCR connectors have high cleanliness (components undergo processes such as electropolishing and cleaning) and good sealing, making them particularly suitable for high-purity systems, high vacuum systems, and high-pressure systems that require no leakage. 
 

Because VCR fittings use metal sealing elements, the rated operating temperature range of VCR fittings is relatively wide (VCR fittings with SUS316L gaskets can reach a temperature rating of 537 ° C). The VCR connector is easy to install and has a small disassembly gap, allowing for repeated disassembly (reinstallation after disassembly requires replacement of new gaskets). 
 

Welding is required between the gland of the VCR connector and the TUBE tube. VCR fittings are generally used in conjunction with automatic welding joints. Automatic welding fittings are used in areas that do not require disassembly, while VCR fittings are used in areas that require disassembly, such as valves and equipment interfaces. 
 

The working principle of VCR connector is to insert the steel pipe into the sleeve, use the sleeve nut and front sleeve for main sealing, and use the hinge clamping effect of the rear sleeve to form a strong grip on the tube.
