A nipple is a short pipe with external threads at both ends, used to connect two internally threaded fittings, valves, or equipment. The hexagonal tube section (Hex Nipple) features a hexagonal cross-section in the middle, providing a convenient clamping point for wrenches during installation. This design allows for easier torque application and more reliable sealed connections.

This fitting uses BSP (British Standard Pipe Thread), a widely adopted standard in Europe and Commonwealth countries. The 55° tooth profile angle design works with both taper threads (BSPT) and parallel threads (BSPP). Threaded connections eliminate the need for on-site welding, offering convenient installation and disassembly - an ideal solution for low-pressure piping systems.

The choice between 304 and 316 stainless steel depends on environmental corrosiveness. While 304 is cost-effective for conventional environments (water, air), 316 offers superior resistance to chloride corrosion and pitting - making it ideal for seawater, salt spray, or chemical applications. The molybdenum content in 316 provides enhanced durability and reliability in corrosive conditions.

The Class 150 hexagonal pipe joint serves as a fundamental component for low-pressure threaded pipeline connections. Its 1/2 inch diameter makes it ideal for connecting instruments, valves, filters, and small equipment. The 316 material extends its use beyond conventional water systems to industrial pipelines, marine applications, and chemical processing - offering versatile, easy-to-install connectivity solutions.
