Product Introduction

Vacuum flange is a type of mechanical component that plays a crucial role in the construction of high-vacuum systems, particularly those used in the fields of physics, chemistry, and engineering research.

Helium leakage test passed before shipping

Plastic flange protective cap is included to avoid flange scratching during transportation

CF vacuum flanges come in various sizes and shapes to accommodate different system configurations. Commonly, they feature a threaded or unthreaded design with standard or custom flange faces.

Assembly Instructions for CF Flanges

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 edege counterbore of nonrotatable flange.

5. Align the mating hole pattern and leak test grooves.

6. Install the proper bolts and tighten had tight. Check to see that the flange faces are parallel.

7. Tighten the bolts 1/4 to 1/2 turns using a star pattern until the flange faces are metal to metal.
