King Combination Nipple, also known as a KC Nipple, is a versatile hose coupling for transitioning from a hose to pipe, equipment, valves or strainers. These end connections are for low-pressure fluid service only. NPT male thread is standard. KC nipples are also available in a grooved end or with a beveled end for welding. Plated steel prevents rust and weathering. Install directly on equipment and then slide the hose onto the stem to eliminate the need for a female swivel in permanent installations.
