What are the common types of VCR connectors?

VCR connector is a type of face sealed connector, and the sealing element uses a metal gasket. By interlocking the internal and external threads to compress the metal gasket, the deformation of the gasket is caused, thereby achieving a sealing effect. So, do you know what are the common types of VCR connectors? 
 

Common types of VCR connectors: 
 

1. According to their different functions, they can be divided into: straight connectors, elbows, tees, reducers, tees, pipe caps, plugs, conversion connectors, etc. 
 

2. According to the connection method of the joint, it can be divided into: ① Both are VCR connections, which are the main body and need to be used in conjunction with internal threaded nuts, joints, and washers; ② One end is a VCR connection and the other end is a threaded connection; ③ One end is connected to a VCR, and the other end is connected to a card sleeve; ④ other. 
 

3. The LOK connector is a whole, including the body, nut, front sleeve, and rear sleeve. For example, if you order a UnionElbow (LOK elbow), you can use it directly without the need to order additional nuts and front and rear bushings (unless as spare parts). 
 

4. The metal gaskets of VCR connectors can be divided into non retaining gaskets and retaining gaskets. 

5. There are many types of glands for VCR connectors, which can be divided into long tube and short tube according to their length; According to the welding form, it can be divided into Butt Weld, Shoulder Weld, and Socket Weld; According to the nuts used in conjunction with it, they can be divided into male and female types. 
 

6. For VCR fittings with threaded connections, it is important to distinguish between the types of pipe threads. There are two common types: NPT (60 ° cone pipe thread, commonly used in American products) and PT (55 ° cone pipe thread, commonly used in China and Japan). 
 

7. In fact, there are two types of TUBE pipes: imperial (such as 1/8 ", 1/4", 3/8 ", 3/4," 1 ") and metric (such as 3, 8, 15, 20, 25mm) (both referring to the outer diameter of the pipe), but the imperial system is commonly used. Therefore, VCR connectors that are compatible with TUBE are also divided into English and metric systems. 

VCR connectors have also been widely used in the semiconductor optoelectronic manufacturing industry. Perhaps due to the immense fame and influence of the Swagelok company, VCR has become synonymous with metal face sealing joints.
