Rubber V Seal – High-Performance V-Shaped Rubber Sealing Rings for Industrial Equipment
Introduction
A Rubber V Seal, also known as a V-Ring Seal, is a flexible, all-rubber axial seal designed to protect rotating shafts and bearings from dust, dirt, grease leakage, and environmental contaminants. Thanks to its simple V-shaped cross-section and excellent elasticity, a rubber V seal provides long-lasting, low-friction sealing-making it ideal for pumps, motors, gearboxes, and industrial machinery.
At Xiamen Jinshun Sealing Technology Co., Ltd., we manufacture high-quality NBR, HNBR, FKM, Silicone, and EPDM V seals with fully customizable dimensions, colors, and hardness levels. With 20+ years of production experience and ISO9001 & ISO14001 certifications, we support global OEM/ODM projects and offer fast sampling, stable quality, and competitive wholesale pricing.
What Is a Rubber V Seal?
A rubber V seal is a lightweight, axial-acting sealing ring installed directly on a shaft. When the shaft rotates, the V seal's elastic lip maintains stable contact with the counterface, forming an efficient barrier that blocks contaminants and prevents lubricant leakage.
Why V-Shaped?
The V-shaped structure combines:
- Support ring – ensures structural stability
- Sealing lip – maintains consistent friction and sealing performance
- Pressing ring – provides uniform pressure for long service life
This design makes V seals extremely versatile for high-speed, low-pressure, and dust-heavy environments.
