Lip seal

NBRV-ringcan

V-type combined oil seal is a reciprocating seal device specially used in hydraulic cylinders and gas cylinders. It is composed of multiple V-shaped cross-section sealing rings, usually including a support ring, several V-shaped sealing rings, and a pressure ring. This structural design enables it to have excellent adaptability and sealing performance, especially suitable for high pressure, heavy load and frequent working conditions. Multi-piece construction: Typically consists of a support ring, multiple V-shaped sealing rings, and a pressure ring. The number of sealing rings can be adjusted according to system pressure. V-shaped sealing lips: Designed with elastic structure that automatically expands under pressure, tightly contacting the shaft or cylinder wall for effective sealing. Replaceable segments: Each component is independent. If one is damaged, it can be replaced individually, improving maintenance efficiency. Clear installation direction: Each V-ring lip faces the pressure direction, forming a "pressure-activated" sealing system. ⚙️ II. Performance Features Suitable for high-pressure environments: Can withstand pressures up to 40 MPa (or even higher depending on material and design). Reliable sealing performance: Maintains a seal even at startup under low or no pressure; does not rely solely on system pressure. Tighter seal with higher pressure: Sealing rings expand automatically when compressed, enhancing contact and sealing performance.
