CF to ASA Nipple — Flat & Grooved

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.
