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

Description: Patent Pending. The VRD-ANB-CD vacuum regulator sets an industry standard for both miniaturization and light weight. It designed to control output vacuum from 0 psig to full vacuum. It is particularly useful when space and weight are critical. The VRD weighs approx. 25 grams in brass and stainless steel.
Both the inlet and outlet ports are tapped 10-32 UNF. Its lightweight design allows convenient in-line mounting however a 10-32 threaded panel mount option is also offered. Applications include medical equipment, instruments, laboratory equipment, ink jet print engines, and semiconductor manufacturing equipment.
Material: Brass or 303 stainless steel.
Seals: Buna-N. Optional materials: EPDM and Viton®

General description :
The M 20 RC System of Vacuum Regulators is designed for dosing gas chlorine and with minor alterations also for other gases, working on the indirect vacuum principle.
The M 20 RC System consists of an M 20 C vacuum regulatorwith dosing valve and an M 300 C ejector.
Dosing can be set manually by means of the dosing valve on the regulator. It starts or stops when the ejector pump switches on or off .

The Fairchild Model 17 Vacuum Regulator is designed for systems that require system vacuum control up to full vacuum. The Model 17 control diaphragm is balanced by a set of three range springs to provide the most stable, responsive and reliable operation. Stability of regulated vacuum or pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the inner valve in accordance with the flow velocity. The Model 17 pneumatic vacuum regulator features control sensitivity of 1/2" water column and a balanced supply valve to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions. In fact, it will deliver this performance with a vacuum supply effect of less than 0.15 of any change in supply vacuum. The Fairchild Model 17 will handle a 40 in Hg, 762 Torr, 102 kPa maximum supply vacuum and offers three (3) output vacuum ranges from 0-5 in Hg, 0-127 Torr, 0-17 kPa, up to 0-30 in Hg, 0-762 Torr, 0-102 kPa. The Fairchild Model 17 pneumatic vacuum regulator offers up to 12 SCFM, 20.4 m3/hr flow capacity.
Features
* Full vacuum capability
* Control sensitivity of 1/2" water column
* High flow capacity
* Balanced vacuum Valve
* Aspirator Tube
* Separate Control Chamber
* Unit construction
