1) In applications where contamination control is critical, military connectors require additional processing for contamination control due to outgassing. Processing generally consists of a bakeout of 125°C and some level of vacuum. A vacuum level of at least 10^-6 torr is preferred. Processing should also include removal of lubricant and replacement with a low outgassing lubricant such as Apiezon-M (manufactured by Metropolitan-Vickers). Removal of ink color bands on contacts may also be required. Some military QPL suppliers offer special low outgassing connectors under commercial part numbers.

2) Connectors may be used in Level 1 and 2 applications.

3) Accessories such as strain relief backshells and seal plugs must be provided separately. Refer to MIL-C-85049 for a selection list of backshells. Use of MS27488 seal plugs in unused contact cavities is recommended.

4) Series I, II, III and IV connectors are not intermateable.

5) Connectors are supplied with contacts. Refer to MIL-C-39029 for a selection of replacement contact part numbers.

6) Consult the latest MIL-DTL-38999 Qualified Products List (QPL) for availability. Other insert arrangements are available but are not preferred due to limited availability.
