Vacuum flange adapter
ISO A&N Corporation

There are two main styles of hybrid adapters:

Flange-to-Flange adapters: These fittings allow transitions between two dissimilar flange families - for example a CF flange to an ISO-QF. Common applications for these fittings include retrofitting an existing vacuum system or adding gauges and instrumentation. A&N produces the following vacuum flange families:

-- CF (Conflat, Del-Seal)
-- ISO QF (NW, KF) and ISO LF (ISO K)
-- ASA/ANSI (ASA 150)
-- ULRIC

Flange-to-Fitting adapters: These fittings allow transitions between standard vacuum flanges and a variety of specialty fittings employed in a vacuum system. An example of this is a QF flange to VCR® fitting. Common uses for these fittings include the introduction of process gases into a chamber or the addition of gauges or instrumentation. These specialty process fittings include:

-- Hose adapters NPT
-- Swagelok®
-- VCR®, Male and Female
-- VCO®, Male and Female
-- Quick Disconnects
-- Baseplate adapters
-- Ball sockets
-- Welch pump adapters
