What is a Hex King nipple? -Cangzhou Hongxin

Product Specification

Product Overview

   A king nipple, also known as a KC nipple or a hose nipple, is a type of pipe fitting widely used in plumbing and fluid

transfer applications.  This fitting features male threads on both ends and a hexagonal middle section, resembling a

thick hexagonal nut.  King nipples are typically made from materials like stainless steel, brass, or galvanized steel to

withstand corrosion and ensure durability.  They are designed to provide a secure and leak-proof connection

between hoses or pipes with female-threaded openings.  King nipples are commonly used to connect hoses or pipes in applications such as fluid transfer, irrigation, and pneumatic systems.  The hexagonal middle section allows for easy installation and tightening using a wrench, ensuring a tight and reliable seal.

  Unlike standard king nipples, the hex king nipple includes a hex nut in the center, providing superior grip and torque resistance during assembly. This design ensures tighter connections and greater reliability in high-pressure or high-vibration environments.

Applications of Hex King Nipples

Hex king nipples are widely used in:

Industrial Pipelines: Connecting valves, pumps, and equipment to flexible hoses.

Liquid Transport Systems: Suitable for water, oil, chemicals, and gases.

Agriculture & Irrigation: Linking rigid pipes to hose-based watering systems.

Petrochemical & Food Industries: Compatible with stainless steel variants for corrosive or sanitary applications.

Note: We do not recommend hex king nipples for high-temperature steam systems unless explicitly rated for such use.

How to install the hex king nipple?

Threaded End: Screw the male thread into a female-threaded pipe or fitting.

Hose End: Attach a flexible hose to the hose shank and secure with a clamp.

Hex Nut: Use a wrench to tighten the hexagonal center for a leak-proof connection.
