MIL-C-5015 Type Firewall Connectors
FRF/FVF/FRA/FVA
How to Order
FRF/FVF Fire wall connectors are designed to meet
the requirements of MIL-C-5015 and prevent the
passage of +1093˚C (+2000˚F) flames for 20
minutes. They incorporate the latest sophisticated
design imporvements nessary to meet the exact-
ing demands of supersonic flight applications. Some
of these features are temerature capabilities to
+204˚C (+392˚F) for more than 1000 hours,
lighter weight, small than other MIL-C-5015 fire-
wall connectors, and crimp front release contacts.
Firewall connectors fulfill the very important appli-
cation of providing a means to penetrate the engine
firewall of military and commercial aircraft with
electrical circuits, and still maintain the integrity of
the flame barrier requiements of the aircraft fire-
wall. These connectors provide protection against
high temperatures, emergency fire-retardant condi-
tions, moisture, atmospheric changes, and are re-
sistant to fuels, cleaning agents, coolants, and
hydraulic fluids. Materials of connector arrange-
ments are designed to meet the requiremetns of
MIL-C-5015 Class K connectors.
The maximum operating temperature noted for
these connectors is the maximum internal hot spot
resulting from any combination of electrical load
and ambient conditions.

NOTES
1. _{Modifier 01: Used for high vibration/shock}
applications
2. _{Less Contacts: Use the Modifier "-FO" or}
"L". The modifier will not be stamped on
the connector. Modifier "-FO" is perferred.
3. _{Numerical FRA/FRF modifiers are assigned}
consecutively as needed and there is no
significance to numerical order.
4. The basic FRA and FRF connectors were
designed for use without ferrules. Ferrules
are suggested when undersized wire is used
so that the grommet seals will not spread
apart (i.e. opened) when the wires are
flexed as the wire maybe too stiff for its
bend to be completely damped out by the
endbell cable clamp.
Dimensions are shown in inches (millimeters).
Dimensions subject to change.
