Pusher Seals
Pusher seals, also known as piston seals, are used to seal pistons and rods in hydraulic and pneumatic systems.

Bellows Seals
Bellows seals are used to seal rotary shafts and prevent the escape of gases or liquids, and are often used in high-temperature or high-pressure applications. 

Non-Contracting Gas Seals
Non-contacting gas seals are used to seal rotary shafts in gas-lubricated systems and use a thin film of gas to separate the sealing surfaces.

Cartridge Seals
Cartridge seals are pre-assembled sealing units that can be easily installed in equipment without disassembling the system.

High-Pressure Seals
High-pressure seals are designed to withstand high pressure and are often used in hydraulic systems and pumps. 

High-Temperature Seals
High-temperature seals are designed to withstand high temperatures and are used in high-temperature environments such as ovens and furnaces.

Split Seals
Split seals are designed to be easily installed and removed from equipment, allowing for maintenance or repairs without disassembling the system.

Sever Duty Seals
Severe duty seals are designed to withstand harsh operating conditions such as high pressure, high temperature, or abrasive environments.
