[Jeff, Daniel]
I cleaned one of the 8" CF Flanges on a 5" long bellows from the Holometer from tape and tape residue. I then cleaned the other end and Jeff and I installed it on the open end of the reducing tee we just installed. The bolts have to be installed from the tee because of the ripple pattern on the bellows. The 2" long bolts can be inserted along side the 6" flange on the tee. I tightened the bolts to 23 Nm to get a steel to steel contact, 2 Nm more than the last 8" CF Thru flange connection.
