SECO holds 6 NSN-identified M939 parts in FSC 6680, Liquid and Gas Flow, Liquid Level, and Mechanical Motion Measuring Instruments., on our own shelf in Augusta, GA — counted, condition-coded and quoted the same business day; 4 are photographed and priced for card checkout.

A part is listed here when its federal item name, SECO's description or its store listing names the M939 or one of its models (M939, M923, M924, M925, M926, M927, M928, M929…). Not every part that fits says so — if yours isn't here, search the full catalog by NSN or part number.
