The /21 shell style is the hermetic box-mounting receptacle of MIL-DTL-38999 Series III, identified by its glass-to-metal sealed insert and eyelet or solder contact terminations rather than crimp. Hermetic versions are used where the connector itself must hold a pressure differential — pressurised instrument bays, cryogenic systems and high-altitude platforms. Class Y denotes a passivated stainless steel shell, and shell 17 arrangement 35 carries 55 size 22D contacts.
