MIL-C-5015 Type Firewall Connectors FRF/FVF/FRA/FVA FRF/FVF Fire wall connectors are designed to meet electrical circuits, and still maintain the integrity of the requirements of MIL-C-5015 and prevent the the flame barrier requiements of the aircraft fire- passage of +1093C (+2000F) flames for 20 wall. These connectors provide protection against minutes. They incorporate the latest sophisticated high temperatures, emergency fire-retardant condi- design imporvements nessary to meet the exact- tions, moisture, atmospheric changes, and are re- ing demands of supersonic flight applications. Some sistant to fuels, cleaning agents, coolants, and of these features are temerature capabilities to hydraulic fluids. Materials of connector arrange- +204C (+392F) for more than 1000 hours, ments are designed to meet the requiremetns of lighter weight, small than other MIL-C-5015 fire- MIL-C-5015 Class K connectors. wall connectors, and crimp front release contacts. The maximum operating temperature noted for these connectors is the maximum internal hot spot Firewall connectors fulfill the very important appli- resulting from any combination of electrical load cation of providing a means to penetrate the engine and ambient conditions. firewall of military and commercial aircraft with How to Order FRF 6 E 12S 3 P X -01 FVF 0 A 12S 3 S X FRA 0 - 12S 3 P FVA 6 - 12S 3 S F0 SERIES PREFIX SHELL STYLE ACCESSORY HARDWARE SHELL SIZE CONTACT ARRANGEMENT CONTACT TYPE INSERT PLARIZATION LESS CONTACTS MODIFIERS SERIES PREFIX CONTACT ARRANGEMENT MODIFIERS (continued) FRF - Flurosilicone elastomers, steel hardware See pages 216-217 12 - Combination 07 and 10 codes with clear chromate (A105) finish 13 - 01 code, with safety wire holes on cou- CONTACT ARRANGEMENT pling nut FVF - Silicone elastomers, steel hardware with P for pin S for socket 14 - 90 endbell (with saddle clamp and clear chromate (A105) finish INSERT POLARIZATION ferrule) FRA - Same as FRF except aluminum hardware W, X, Y or Z in accordance with MIL-C-5015.
