Expert engineering insights and technical guidance regarding design specifications, pressure ratings, thread tolerances, materials, and installation best practices for industrial Brass Pipe Double Nipple.
A Brass Pipe Double Nipple (often called an equal hex nipple) is an externally threaded fitting with male threads on both ends separated by a central hexagonal section. It is designed to connect two female-threaded fittings, valves, manifolds, or strainers together in a tight, rigid, in-line assembly.
A barrel nipple is unmachined pipe with threads cut at each end and no wrench flat, making it difficult to tighten without using a pipe wrench that gouges and weakens the pipe wall. A hex double nipple features an integral central hex shoulder that allows positive, damage-free torque application with a standard open-end wrench.
Operating pressure ratings range from 3,000 PSI (207 bar) for 1/8″ and 1/4″ sizes, 2,500 PSI for 3/8″, 2,000 PSI for 1/2″, down to 1,200–1,500 PSI for 3/4″ to 1″ sizes, tested with an engineered 4:1 burst safety factor.
Pioneer supplies double nipples with American National Pipe Taper (NPT per ASME B1.20.1), British Standard Pipe Taper (BSPT per ISO 7-1), and British Standard Pipe Parallel (BSPP per ISO 228-1 with machined undercut sealing faces).
Pioneer manufactures double nipples from high-grade extruded brass bar stock conforming to IS 319 Gr. 1, CW614N / CZ121, and ASTM B16 C36000, ensuring maximum tensile strength, dense microstructure, and zero internal porosity.
Yes. Brass double nipples are standard hardware in pneumatic FRL units, air compressors, diesel fuel filters, and lubricating manifolds due to their excellent vibration resistance and non-sparking characteristics.
Apply 2 to 3 wraps of high-density PTFE tape in the thread direction, thread the nipple finger-tight into the first female port, tighten 1.5 to 3.0 turns past finger tight using an open-end wrench on the hex flats, and then thread the second component onto the opposite end using a backup wrench.
Yes. While standard hex nipples have compact overall lengths, Pioneer manufactures extended-length double nipples (custom standoff lengths up to 150 mm) for applications requiring spacing between valves and manifolds.
Standard finish is natural bright brass. Optional bright nickel plating (5–8 µm) or electroless nickel plating (ENP, 10–25 µm) can be applied for superior atmospheric and chemical corrosion resistance.
All products are backed by EN 10204 Type 3.1 Mill Test Certificates verifying chemical composition, tensile properties, and 100% thread dimensional compliance.
