The JAE GT21-1P-R is a retainer accessory for the GT21 series of connectors — a secondary lock that seats over the terminals inside a GT21 housing to prevent back-out under vibration or cable strain. It is not a housing or a terminal; it is the piece that goes in after the wires are crimped and inserted, locking each contact in its cavity. The gray polybutylene terephthalate (PBT) body matches the standard GT21 housing material for thermal and chemical compatibility. This retainer is designed specifically for use with GT21 housings, so the fit is confirmed: if your BOM calls out a GT21 housing, this retainer is the matching secondary lock.
