King Combination Nipple 3/4"" Fitting

King Combination Nipple 3/4"" Fitting

The 3/4-inch King Combination Nipple, often referred to as a KC nipple, is a versatile hose fitting designed for low-pressure fluid applications on concrete mixer trucks. It features a 3/4-inch hose shank (barb) on one end that inserts into a 3/4-inch ID hose, and a 3/4-inch Male NPT thread on the opposite end for connecting to valves, pumps, or plumbing fixtures. In concrete equipment, these fittings are essential for routing water lines, assembling washout hoses, and connecting slump meters. The barbed end requires a hose clamp or crimp collar to secure the hose and prevent leaks during operation. This fitting provides a reliable, leak-resistant transition between flexible hoses and rigid threaded components in general mixer applications.
