Oil seals V
V-ring seals are axial seals that are fitted directly onto the shaft and protect against dust, dirt and moisture. Unlike conventional seals, V-ring seals do not require a special housing recess. They are fitted onto the shaft and seal by contact with a flat surface or another V-ring. They are often used as an additional seal to extend the service life of the assembly. At Hydraulic Seals Store, you’ll find V-rings made from NBR and other elastomers, available from stock with fast delivery in Romania.
Features of V-rings and their role in sealing
V-rings are designed for axial sealing. The rubber lip of the V-ring makes contact with a flat surface and ensures effective sealing even at high rotational speeds. They are easy to fit by pressing them onto the shaft, without the need for a special bore in the housing.
Features of V-seals
Specific profile for protection and sealing
The special shape of the V-ring helps it to adapt to the sealing surface and compensate for minor misalignments or radial runout of the shaft. The elastic material, usually NBR, ensures constant and effective contact.
Use in applications where additional protection is required
V-seals provide additional protection for the main seals, preventing dust, mud or water from reaching the main seal. They are widely used in agriculture, construction and industry.
Where are V-seals used?
- bearings and shafts exposed to dust or moisture;
- agricultural machinery (axles, drive wheels);
- construction machinery (wheels, drums, shafts);
- industrial equipment with rotating shafts;
- as an additional seal alongside the main oil seal.

Frequently Asked Questions
What are V-rings?
V-rings are axial rubber seals fitted directly onto a shaft. They seal by contact with a flat surface and are used to protect against dust, dirt and moisture.
Where are V-rings used?
V-rings are used on bearings, shafts exposed to contaminated environments, and agricultural and construction machinery, as an additional seal upstream of the main seal.
How do I choose the right V-ring seals?
Select the V-ring seal based on the shaft diameter and the required width. The standard material is NBR; FKM is recommended for high temperatures.
What materials are used for V-seals?
V-ring seals are usually made from NBR (for standard conditions) or FKM (for high temperatures or aggressive environments). The choice of material depends on the operating conditions of the shaft.
