Top 10 v ring seal Suppliers in China 2026

Introduction to V Ring Seal

V ring seals, also known as vee - ring seals, are mechanical seals with a V - shaped cross - section. They are commonly used in a variety of industrial applications to prevent the leakage of fluids such as oil, water, and gases. V ring seals are designed to be installed in a gland or groove, and their shape allows them to adapt to different shaft sizes and operating conditions. They can provide both radial and axial sealing functions, which makes them suitable for use in rotating shafts, reciprocating rods, and static applications. The materials used for V ring seals can vary, including rubber, silicone, fluorocarbon, and other elastomers, each offering different levels of chemical resistance, temperature tolerance, and wear resistance.
