O-Ring V Type Size List

O-Ring V Series, defined by JIS B 2401 (Japanese Industrial Standard), is designed for vacuum and high-pressure applications. Featuring larger cross-sections, the V-type offers excellent sealing performance in deep grooves and static applications under extreme conditions.


🔧 What is the JIS V-Type O-Ring?

  • “V” stands for Vacuum or special static sealing

  • A sub-series of JIS B 2401 (alongside P, G, and S)

  • Uses larger cross-section (CS) for better sealing in static & high-load environments

  • Suited for deep groove, vacuum chamber, and high-pressure systems

  • Specified in metric units (mm)
