Vee packing seal V-shaped combination

The V-ring, also known as the V-ring or V-ring, is a common sealing solution that is widely used in hydraulic and pneumatic systems. This article will delve into the design, function and application of V-shaped sealing rings, revealing their importance in various industries

Understand the V-ring

The V-shaped seal ring is named for its distinctive V-shaped cross section, which takes on a shape similar to the letter "V "when viewed from the side. This design consists of multiple sealing components stacked together to create a tight seal when pressurized within the sealing chamber or sealing housing.

Part of V-shaped sealing ring

Sealing element: The sealing element of the V-ring is usually made of an elastic material, such as butadiene (NBR), fluororubber (FKM) or poly (PU).

These materials are flexible and resilient, ensuring effective sealing under high pressure and temperature variations.

Support ring: V-shaped sealing rings usually include support rings, made of materials such as polytetrafluoroethylene (PTFE) or nylon. Support rings provide structural support and help distribute pressure evenly across the sealing elements.

Main features and advantages

Versatility: The V-shaped seal ring is versatile and can be used in a variety of applications such as hydraulic cylinders, pumps, valves and other fluid power equipment. High pressure resistance: Thanks to its robust design and materials, the V-shaped seal ring can withstand the high pressure environments common in hydraulic and pneumatic systems. Effective sealing performance: The V-shaped sealing ring is configured with a stack of incense and provides multiple sealing points, enhancing its sealing performance and reliability. Temperature: Depending on material selection, V-shaped seals can exhibit excellent temperature resistance for both high and low temperature applications.

Application of V-shaped sealing ring

V-shaped seals are used in a wide range of industries and applications, including:

Hydraulic and pneumatic cylinders

Industrial machinery

Oil and gas exploration and production

Aerospace and aviation systems

Mining and construction machinery


V-shaped seal rings play a key role in ensuring the integrity and efficiency of hydraulic and pneumatic systems. Its rugged design, effective sealing performance and versatility make it an indispensable component in fluid power applications. Understanding the design principle of the V-shaped sealing ring and the application scenario is crucial to selecting the sealing solution for the specific operational requirements.
