Product Description

CF Flange Overview

CF flanges are available with tapped or untapped holes. Tapped flanges are available in UNC/UNF or metric threads. Tapped flanges have through holes, so bolts may protrude slightly from the back of the flange when fastened to an untapped flange. Untapped CF flanges can be fastened to each other with stainless steel bolts and hex nuts or plate nuts. Silver plated bolts eliminate the need for anti-seize compound in clean room environments.

Assembly Instructions:
  1. Apply a small amount of high temperature anti-seize compound to the bolt threads.
  2. Check that both flange surfaces are clean and sealing edges are free from nicks and scratches.
  3. Using clean, lint free gloves, unpack gasket.
  4. Place gasket in the knife edge counterbore of nonrotatable flange.
  5. Align the mating hole pattern and leak test grooves.
  6. Install the proper bolts and tighten hand tight. Check flange faces are parallel.
  7. Tighten bolts 1/4 to 1/2 turns using a star pattern until metal-to-metal contact.
  8. Torque the fasteners to the listed value using the same pattern.

Product Detail

* U.S. manufacturers of CF flanges name them according to their outer diameter measured in inches (e.g., CF600 is approx. 6 inches OD).

* European identification varies; measurements are based on outer diameter (mm), inner diameter counterbore, or inner diameter of the largest through bore.

* U.S. and Metric CF flanges are compatible. The design difference lies in the metric bolt thread machined into tapped bolt holes.
