CF to ISO Adapter Flanges

Adapter flanges allow the mating of one type of flange system to another. All of our flange adapters are manufactured from 304 series stainless steel tubing and flanges.

NOTE: Mixing flange types using adapters is possible but not recommended unless necessary to match existing components or fittings. However, using one flange type for chamber-mounted components and another type for foreline components is common practice.
