MIL-C-5015 Standard Circular BFH/TBFH The BFH is a hermetically sealed version of the BFR bulkhead fitting. The TBFH-100 is a jam nut-mounted, thru-bulk- head receptacle for panel thicknesses of .187 (4.75) thru .312 (7.92). Sealing against the bulk- head is accomplished by an O ring seal. The TBFH-200 is similar to the TBFH-100 with a longer overall length for panel thicknesses of .375 (9.52) thre .750 (19.05). The TBFH-110 is the hermetically sealed version of the TBF thru-bulkhead receptacle. It is flange mounted and mates with 3106, 3107 and 3108 plugs. Contacts are sealed to achieve hermeticity preventing air leakage in excess of one micron cubic foot per hour at a pressure differential of one atmosphere. Receptacles with leak rate of .001 micron cubic foot per hour. and lower, are also available. Materials and Finishes Contact and shells are steel. Standard finish is clear chromate over cadmium. Other finishes are available for high temperature and special applications.
