Style 741

Style 741 Vic-Flange® adapter is designed for directly incorporating flanged components

with ANSI CL. 125 or CL. 150/PN10 and PN16 bolt hole patterns into a grooved pipe

system. Sizes 2 – 12"/50 – 300 mm are hinged for easy handling with integral end tabs

which facilitate assembly. Sizes 14 – 24"/350 – 600 mm are cast in four (4) identical

segments which are interconnected as assembly is completed.

The design incorporates small teeth inside the key shoulder I.D. to prevent rotation

(excluding 159 mm size). These teeth should be removed when Vic-Flange adapter is

utilized with a Victaulic Series 700 grooved end butterfly valve, Schedule 5 pipe or

plastic pipe.

Vic-Flange adapters may only be used on Vic-300® butterfly valves on one side in 2 –

8"/50 – 200 mm sizes. They are not recommended for 10 and 12"/250 and 300 mm

sizes.

Vic-Flange adapter Style 741 is not recommended for use with Victaulic Series 709

butterfly valves (contact Victaulic for recommendations). They may only be used on one

side of Victaulic Series 700 butterf ly valve, sizes 2 – 4"/50 – 100 mm fitted with standard

or lever-lock handles. Vic-Flange adapter must be assembled so it does not interfere with

handle operation.

Style 743

Vic-Flange Style 743 flange-to-groove adapter permits direct connection of ANSI Class

300 flanged components into a grooved system. The two-piece, hinged housing engages

into the pipe groove and bolts directly to any standard flanged component. The

conventional bolt hole pattern allows for easy, fast assembly. Style 743 rotates 360° for

proper alignment of bolt holes before tightening. Vic-Flange gaskets utilize the Victaulic

pressure-responsive design, sealing on the pipe end and directly to the opposing flange

face. No standard flange gasket is required.

Style 743 is designed to mate with raised-face flanges, but can be used with flat-face

flanges by removing the raised projections on the outside face of the flange.

VIC-FLANGE NOTES Because of the outside flange dimension, Vic-Flange should not be used within 90° of one another

on a standard fitting. When wafer or lug-type valves are used adjoining a Victaulic fitting, check disc

dimensions to assure proper clearance.

Vic-Flange adapters should not be used as anchor points for tie-rods across non-restrained joints.

Mating rubber faced flanges, valves, etc., requires the use of a Vic-Flange washer.

Vic-Flange gaskets must always be assembled with the color coded lip on the pipe and the other lip

facing the mating flange.

8/8/2019 741 Flange


1. The Style 741 (2 – 12"/50 – 300 mm) design incorporates small teeth inside the key shoulder

I.D. to prevent rotation. These teeth should be removed when Vic-Flange adapter is utilized with

a Victaulic Series 700 grooved end butterfly valve, Schedule 5 pipe or plastic pipe. Vic-Flange

adapter Style 741 may only be used on one side of Victaulic Series 700 butterfly valve, sizes

2 – 4"/50 – 100 mm fitted with standard or latch-lock handles.

2. Vic-Flange adapter must be assembled so it does not interfere with handle operation. Because of

the outside flange dimension, Vic-Flange adapter should not be used within 90° of one another on

a standard fitting. When wafer or lug-type valves are used adjoining a Victaulic fitting, check disc

dimensions to assure proper clearance.

3. Vic-Flange adapters should not be used as anchor points for tie-rods across nonrestrained joints.

Mating rubber faced flanges, valves, etc. requires the use of a Vic-Flange washer.

4. Area A-B noted in the above drawing must be free from gouges, undulations or deformities of any

type for effective sealing.

5. Vic-Flange adapter gaskets must always be assembled with the color coded lip on the pipe and

the other lip facing the mating flange.

6. Vic-Flange hinge points must be oriented approximately 90° to each other when mated.

7. Flange Washers: Vic-Flange adapters require a smooth hard surface at the mating flange face for

effective sealing. Some applications for which the Vic-Flange adapter is otherwise well suited do

not provide an adequate mating surface. In such cases, it is recommended that a metal (Type F

phenolic for Style 641 with copper systems) Flange Washer be inserted between the Vic-Flange

adapter and the mating flange to provide the necessary sealing surface.

Typical applications where a Flange Washer should be used are:

A. When mating to a serrated flange: a flange gasket should be used adjacent to the serrated

flange and then the Flange Washer is inserted between the Vic-Flange adapter and the f lange gas-

ket.

B.When mating to a wafer valve: where typical valves are rubber lined and partially rubber faced

(smooth or not), the Flange Washer is placed between the valve and the Vic-Flange adapter.

C. When mating a rubber faced flange: the Flange Washer is placed between the Vic-flanges and

the rubber faced flange.

D.When mating AWWA cast flanges to IPS flanges: the Flange Washer or Transition Ring is placed

between two Vic-Flange adapters with the hinge points oriented 90° to each other. If one flange

is not a Vic-Flange adapter (e.g., flanged valve), then a flange gasket must be placed adjacent to

that flange and the Flange Washer inserted between the flange gasket and the Vic-Flange adapter.

Transition rings rather than Flange Washers must be used when mating Style 741 to Style 341

Flange Adapters in sizes 14 – 24"/350 – 600 mm.

E. When mating to components (valves, strainers, etc.) where the component flange face has an

insert: follow the same arrangement as in Application 1.

When ordering Flange Washers, always specify product style (Style 741, 743, 341, 641, 994) and

size to assure proper Flange Washer is supplied.
