The VCR joint is a kind of sealing joint commonly used in semiconductor photoelectric manufacturing industry. The [meta]l gasket used for sealing elements is used to press the [meta]l gasket through the interlock of internal and external threads to produce certain deformation of the gasket, so as to achieve the sealing effect.
So what are the characteristics of the VCR connector? Due to its high cleanliness and good tightness, the VCR joint is more suitable for the ultra-high purity system, ultra-high vacuum system and high-pressure system with higher requirements for no leakage. Also because of the use of [meta]l sealing elements, its rated operating temperature range is wide, at the same time, the VCR joint is easier to install, also because it has a small disassembly gap can also be repeatedly disassembled.
The following small make up for you to explain the main material of each component of the VCR joint, so what are their materials? SUS316L or SUS316L is the material of connection, [body] and nut. SUS316L, nickel or copper is the material of gasket. However, copper gasket is rarely used nowadays.
