Ordering Information

   Typical Part#:     SmallerWGSize/LargerWGSize -Length(In) -SmallerFlange -LargerFlange
It is possible to change the flanges on the standard model number, but the order you specify them in is important.  The first flange corresponds to the smaller WG size and the second flange corresponds to the larger WG size.  In order to change the length of a standard model consult factory for more information.

 

Example:  P/N 284/340-11.5-6-2 is a:

WR284 to WR340 transition -11.5 inches long - Cover flange on WRD250 - CPRF flange on WG340

 

See ATM Flange page for more information on flanges.
