M85049/79-17W03 is a 90° EMI/RFI environmental backshell from the M85049/79 slash sheet (AS85049/79), used to terminate a cable screen and seal the rear of a MIL-DTL-38999 Series III or IV connector while turning the cable through a right angle. Shell size is 17 (shell letter E), variant 03, finish W — olive drab cadmium over electroless nickel — in aluminium alloy, QPL qualified. The 79 sheet carries a dash number equal to the shell size, followed by the finish letter and a two-digit variant; 17W03 therefore reads shell 17, finish W, variant 03. Also specified against EN3645 in European programmes.
