CF vacuum half nipple rotatable are mainly used in ultra-high vacuum systems,
A series of tests are required before shipment, including vacuum sealing testing, dimensional accuracy testing, etc., to ensure the quality and performance of the joints.
The packaging before shipment usually uses anti-static packaging to protect the joints from static electricity damage.
When assembled and used, CF vacuum half nipple are usually connected by metal sealing to ensure the vacuum degree and sealing of the system.

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.
