M25038/3-222219 x 34CopperNickel23.7 0.033  0.040.0544.1500-Wire size 20 AWG and 22 AWG shall be constructed with nickel-coated high-strength copper strands. -The conductor strands shall have an annular nickel coating, whose weight shall be not less than 27 percent of the total weight of the nickel-coated strand. -These wires shall comply with the sealing range requirements for firewall connectors as specified in MIL-DTL-5015, MIL-DTL-38999, and MIL-C-83723. -The 22H wire is defined as heavy-wall or thick-wall version of size 22 wire for use in specific applications. It is considered to be “light weight, small diameter” when compared with the normal weight size 22 of MIL-DTL-25038/1. The 22H wire should only be used with a size 20 type contact for MIL-DTL-38999 connectors.
