MIL-C-5015 Firewall Connectors
MS-K firewall connectors have met and are qual-
ified to the fireproof test of MIL-C-5015. This test
requires that a connector mounted to a firewall will
continure to operate for 5 minutes in case of fire and
prevent the passage of flame for 20 minutes. These
connectors are not environmentally sealed but oper-
ate continuously at temperature up to +177˚C
(+350˚F). MS-K connectors have crimp type con-
MS-K
tacts; thermocouple contacts must be orderd sep-
arately and are solder type unless otherwise re-
quested on order. Cavities that will contain the
thermocouple contacts and contact material must
be specified when ordering.

Assembly Instructions
Recommended Procedures
* 1. Remove Formica retaining ring (or the ce-
ramic retaining ring) from contact (Figure 1).
2. Crimp contact to wire.
3. Slip endbell (or junction shell), retaining ring,
and washer over wire bundle.
4. Push contact thru rear insulator. (Contact
should extend sufficiently to accomplish
Step 5.)
5.
MS-K
Attach Formica retaining ring onto the con-
tact (see Figure 1).
6. Seat each contact securely in rear insulator.
7. Assemble front insulator on engaging end of
contact.
8. Slide insulator assembly into hardware.
9. Slide washer and insulator retaining ring into
place, making sure that insulator retaining is
fully seated in groove.
10. Slide endbell or junction shell down wire
bundle and attach to shell (or barrel).

*NOTE: For MS-K Assembly it is not neccessary to remove the ceramic retaining ring used on sizes 16
and 12 contacts for MS-K
providing
that the crimp tool M22520/1-01 is used with the TH119 turret.
However, the formica ring must be removed if using the crimp tools listed below.
When using the MS3191-1 (or CCT-1612) crimp tool with property locator, both the ceramic or formica
retaining ring for sizes 16 and 12 contacts must be removed. For sizes 8, 4, and 0 contacts, the
ceramic or formica retaining rings must be removed before crimping.
