ISO Flanges & Fittings are standardized vacuum components used for low, medium, and high vacuum applications. ISO flanges are ideal for larger diameter vacuum systems and provide modular, reusable, and easy-to-assemble solutions.
Common ISO Fittings
ISO Elbows
- 90° and 45° elbows for changing the direction of vacuum lines.
ISO Tees and ISO Crosses
- Used to create branch lines or connect multiple vacuum components.
ISO Adapters
- Connect ISO flanges to other flange systems, such as CF or KF flanges.
Blank Flanges
- Used to seal off unused ports.
ISO Reducers
- Transition between different ISO sizes (e.g., ISO100 to ISO63).
Flexible Hoses
- Corrugated stainless steel hoses for vibration damping or system flexibility.
Advantages of ISO Flanges & Fittings
- Modular and Flexible: Easy to assemble, disassemble, and reconfigure using clamps (ISO-K).
- Reusable: Components, including flanges, clamps, and seals, can be reused multiple times.
- Suitable for Large Systems: Ideal for larger-diameter vacuum lines, ranging from ISO63 to ISO630.
- Reliable Sealing: O-ring seals ensure a robust and leak-tight connection.
- Quick Assembly: ISO-K systems allow for rapid installation and maintenance.
- Cost-Effective: More affordable compared to CF flanges for applications not requiring UHV.
