Description 

Steel is cast into ingots in the conventional way (airmelted). 

Individual ingots are then remelted in an EFR unit as 

shown in the diagram. This significantly increases the final 

steel quality attainable. 

Rapid heat extraction by the controllable melt rate 

permits the elimination of the gross macro segregation 

and inhomogeniety inherent in all conventionally cast 

ingots and gives excellent uniformity of structure. 

Strict control of remelting parameters allows a substantial 

reduction in total inclusion content. The EFR process virtually 

eliminates all harmful brittle oxide stringers 

(B types in ASTM E45 cleanness assessment) and any remaining 

oxides are small round ‘D’ types. Because the steel has had 

impurities removed and has a superior homogeniety, its mechanical 

properties are improved 

(e.g. ductility and impact resistance in the transverse direction) and 

are remarkably consistent. 

The austenitic grade 316LN, which MDC Vacuum uses, has a 

nominally nil content of ferrite and very low magnetic permeability 

making it suitable for the most demanding UHV applications. 

All MDC Vacuum 316LN Euro Conflat ® CF series flanges are 

Electroflux refined.

CF Flange and tube sizes 

Standard series CF flanges are fully compatible with, and can be 

sealed to,Varian Conflat ® (CF) types and similar flanges made by 

Balzers,VG and others. They are designed to accept standard ‘inch 

outside diameter’ stainless steel tubes which are detailed in the 

adjacent chart. 

MDC Vacuum follows the widely used convention of categorising 

different sizes of UHV flange by using a ‘DN’ specification.‘DN’ is 

the acronym of the French term ‘Diamètre nominal’ which 

translates as ‘Nominal bore’. The bore referred to is that of the 

tube that fits inside the designated flange. The bore is ‘nominal’ 

because of the variation in tube wall thickness. 

Euro CF series 

Euro CF fittings use the ‘oversize’ tubes which allow greater 

internal diameters than conventional fittings. 

MDC Vacuum reference for CF flanges 

a bored flange is described as CF(X)-(Y) where 

a blank flange is described as CFB(X) 

a tapped flange has suffix ‘T’ 

a spigotted flange has suffix -S 

Rotatable flanges are described: CFR(X)-(Y) 

CFBR(X) 

316LN flanges are described: CFL 

X outside diameter in mm 

and 

Y outside diameter of the matching tube in mm 

DN nominal inside diameter of tube

General specifications 

MDC Vacuum Limited offers two types of CF flange in either 304 

or 316LN for applications where very low magnetic permeability is 

required. 

The OFE copper metal seal 

The reliable sealing performance of CF flanges is a result of the 

geometry of the design which ‘captures’ the gasket material. When 

the conical sealing edge of the flange is pressed into the OFE 

(oxygen-free electronic grade) copper gasket, a lateral cold flow of 

the gasket material occurs. This cold flow is limited by the vertical 

flange wall. Further material flows away from the seal area is 

severely limited and high interface pressures are developed. These 

pressures cause gasket material to fill surface imperfections and 

produce a highly reliable seal.

UHV Series 

Description 

CF double-sided flanges are designed to be inserted between two 

flanges of the same size. This provides a simple method for adding 

thermocouple gauge tubes or up-to-air valves to a system with 

virtually no change in conductance or pumping speed. 

All CF double-sided flanges are made of 304ss material. Each 

assembly requires two gaskets and longer-length bolts. 

MDC Vacuum does not recommend stacking more than one 

double-sided flange in a single assembly.

Tubulated CF flanges 

UHV Series 

Tubulated CF flanges Half nipple 

Description 

MDC Vacuum CF tube fittings are convenient building-block 

components. They offer great flexibility in the design and 

construction of high and ultra-high vacuum systems. All fittings are 

fabricated from stainless steel drawn and welded vacuum tubing. 

Features 

■ Weldable fitting 

■ Fixed or rotatable CF flanges 

■ Custom lengths available on request 

Features

■ High temperature rated to 450°C

See table 

To facilitate assembly alignment, a rotatable flange is supplied 

opposite a non-rotatable flange on each axis. Elbows are supplied 

with two rotatable flanges. 

In general, reducers are used for a change in size of flanges within 

a single method of sealing, such as CF to CF. Reducers may be 

either zero-length or include a section of tubing between flanges. 

Non-zero-length reducers are also called nipple reducers and have 

either a straight tube or a conical section between flanges. 

In general, hybrid adaptors provide a transition between two 

different methods of creating a vacuum seal, such as metal seal CF 

to elastomer seal ISO. 

Reducing tees and crosses have a single main tube with main 

flanges and a smaller diameter reducer tube with a reducer flange 

or flanges. 

Main flanges: 

1 fixed 

1 rotatable 

Reducer

■ Main flanges are on the larger tube 

■ Reducer flange is on the smaller tube 

■ In general, each axis includes one rotatable and one non-rotatable flange

The tapped flange adaptor is a nipple with a minimum length 

for mating two tapped flanges. Studs must be screwed into 

each tapped flange prior to installing the adaptor. The tapped 

flange adaptor has clearance holes on each flange which slip 

over the studs. Nuts are then fixed to the studs to complete 

installation. Studs, nuts and washers are provided with the 

adaptor.
