Hoses with NW and ISO flanges are also available In 10, 20 and 40 Inch (metric equivalent) lengths. CF and ASA flanged hoses have one rotatable and one nonrotatable flange for ease of bolt hole alignment. ASA flanged hoses may require an O-ring groove on one flange for proper installation. Be sure to specify. NW to CF adapter hoses provide a flexible transition between components with NW and CF flanges. NW hoses are available in medium wall ?FH-?
