a

 

flange,

 

select

 

a

with

 

a

 

thread

 

that

 

is

 

above

 

the

 

plane

 

of

 

the

 

flange.

  

 

a.

 

The

 

LVU2818,

 

LVU2826

 

&

 

LVU2832

 

series

 

works

 

well

 

with

 

Flange

 

installations.

 

b.

 

Avoid

 

the

 

use

 

of

 

blind

 

flanges

 

with

 

tapped

 

threads

 

or

 

flanges

 

where

 

the

 

threads

 

are

 

even

 

with

 

the

 

plane

 

of

 

the

 

flange,

 

such

 

as

 

the

 

Banjo

 

1"

 

Poly

 

ANSI

 

Flange

 

(series

 

AF100).

  

c.

 

Use

 

a

 

flange

 

with

 

a

 

2”

 

thread

 

and

 

add

 

a
