A nippled metal hose, also known as a beaded metal hose, is a flexible connector designed for dynamic applications requiring movement, vibration dampening, and stress relief. Its defining feature is the cylindrical ends (nipples or beads) which allow for the use of clamps, bands, or flanges to secure the hose onto matching pipe stubs or fittings.

This connection method offers versatility and ease of installation, making nippled hoses a popular choice for lower to medium pressure services. The corrugated metal body, often made of stainless steel, provides excellent flexibility and resistance to corrosion, temperature extremes, and fatigue.

Common applications include connecting to equipment like pumps and compressors, in HVAC systems, for exhaust lines, and in various industrial machinery where absorption of movement is critical. They are particularly valued in situations where a welded or threaded connection is not desired or practical.
