SELECTION & APPLICATION GUIDE
How to specify ISO Flanges & Components
ISO-K and ISO-F components are designed for large-diameter vacuum piping where conductance and serviceability are important. ISO-K uses claw clamps for rapid assembly; ISO-F uses bolted flanges for a more permanent connection. Tube size, seal material, clamp arrangement, pressure differential and mechanical support should be reviewed together.

Technical questions
What is the difference between ISO-K and ISO-F?
ISO-K is clamp-connected for serviceability; ISO-F uses bolts for rigid, permanent piping.
Where are ISO flanges typically used?
Large pumping lines, coating systems, furnaces and industrial high-vacuum equipment.
APPLICATIONS
