MIL-C-5015 Bulkhead Receptacles
How to Order
TBF and BFR pressurized bulkhead receptacles
mate with standard MS type plugs (3106,3107 and
3108) if contact arrangements correspond. Both
the BFR and TBF have resilient insulators. The TBF
(thru-bulkhead fitting) version has a double-faced
contstruction allowing mating from both ends. An O
ring is supplied as standard on both the BFR and the
TBF. Contacts are silver plated copper or brass
alloy. Shells are aluminum alloy.

TBF thru-bulkhead fittings have pressurized resil-
ient insulators. Special douple-face pin and socket
contact construction permits cable components to
be wired and tested in the shop and then to be
plugged into the mounted TBF plug to complete the
installation. The TBF mates with 3106, 3107 and
3108 plugs.
