In certain extreme applications, a part made of individual segments may meet your critical performance requirements better than a single-piece unit.
QUALISEAL® CONTROLLED GAP/BUSHING
Really two pieces in one, Qualiseal® Controlled Gap/Bushing seals are the best solution when pressure is an issue.
Controlled gap or bushing seals are comprised of a carbon insert that is shrink-fitted into a separate retaining band. This floating circumferential ring assembly grows at a rate similar to that of the shaft when exposed to elevated temperatures.
Under normal operating conditions, the pressure on the airside is higher than the pressure on the oil side. This creates some air leakage through the controlled gap between the carbon ring and shaft. The differential air pressure, along with the spring load, provide the closing force necessary to maintain contact between the carbon and housing secondary sealing face. Meanwhile, the shaft turns freely within the carbon ring.
The seal design also features a unique stabilizer ring with fins which minimize stress on the carbon ring, thereby maintaining the roundness of the circumferential ring assembly. The dimensional tolerance of the critical inside diameter of the bushing ring is tightly controlled to minimize leakage variations.
Product Applications
- Aerospace Industry

- Available in a wide variety of materials suitable to a broad range of applications
- Often paired with other seals to create sealing systems that meet demanding requirements
Design Configurations:
- Single seal for dual pressure conditions
- Spring-loaded double back-to-back seal
- Separable designs to facilitate replacement and/or rework of internal components
- Double tandem seal arrangement for sealing a combination of liquids and gases
- Multiple labyrinth ring assemblies
- Housing for mounting directly onto equipment case
QUALISEAL® SEGMENTED SEALS
Segmented seals ride directly along the shaft and are primarily used in low-pressure applications.
These seals contain a series of segmented carbon rings which contact the shaft or rotor. Segments inside the seal housing are kept in the proper location by anti-rotation keys or pins. A secondary seal is formed by the axial spring loading of the seal rings against the internal surface of the housing face. During movement, a continuous seal is always in contact with either the primary or secondary sealing surfaces.
Product Applications
