The K77 suffix denotes a Series 77 kit/accessory designation in Ross Controls' model-number structure, and this designation is shared with other Series 77 components such as 893K77 (1/4 in NPTF Female Port Block) and 743K77 (Valve Body Kit), which illustrates the range of compatible accessories in the same catalog family.
