JPE Product Spotlight | Applications and Advantages of VMS Product Series

As automation and smart technology continue to evolve, precision manufacturing processes have also undergone rapid advancement, leading to improvements and breakthroughs in various application solutions for complex processes.

The JPE VMS (Vacuum Metal Seal) metal gasket sealing fitting series, known for its reliable raw materials and outstanding design, is tailored to meet the high specifications for industries with stringent requirements for space and purity. It has become a trusted choice among customers due to its convenience in on-site assembly and efficient operation.

The JPE VMS, or Vacuum metal seal, consists of several precision-engineered components. Its working principle involves sealing when the gasket is compressed between the outer threaded nut or fitting body and the inner threaded nut, completing the seal.

【Typical VMS Components】

While the working principle may seem simple, meticulous attention is paid to product precision and quality standards from material selection to manufacturing processes. JPE offers pure 316L stainless steel, serving high-purity gas or fluid fields such as semiconductor and biochemistry, to provide leak-free service within a vacuum range from negative to positive pressure.

Key features of the JPE VMS metal gasket surface sealing fitting include:

1 Both the conduit and fitting body undergo precision surface treatment with a standard polish of Ra 0.25um.

2 Equipped with two test ports for leak testing convenience.

3 Clearly marked with manufacturer, material grade, and process traceable numbers for traceability.

4 Precision-engineered metal gasket for optimal sealing performance.

5 Silver-plated internal threads on the VMS nut for increased lubrication and reduced wear.

During the manufacturing process at JPE, the VMS fitting design undergoes helium leak testing. The maximum leak rate when using silver-plated gaskets is 4.1 x10^-9mbarl/s , while without silver plating, it is 4.1x10^-11mbarl/s

As process nodes in industries like semiconductors continue to update, equipment systems are increasingly demanding high purity. With the many advantages of the JPE VMS metal gasket surface sealing fitting, it provides customers with a convenient solution for building high-purity systems. In recent years, JPE has focused on expanding product categories and improving the quality of high-precision products, providing better choices and application solutions for the upgrade and evolution of precision industries!
