The Brass Close Nipple is a compact, threaded pipe fitting designed specifically for connecting two female threaded pipes in very close proximity. Made from high-quality brass, this fitting ensures excellent corrosion resistance, durability, and reliable sealing for plumbing, HVAC, and industrial piping applications. It is primarily used where a short connection is required without any leak path between the joined pipes. The Brass Close Nipple is available in various nominal sizes, following standard pipe thread types such as NPT (National Pipe Taper) and BSP (British Standard Pipe), making it compatible with a wide range of piping systems. Some variations feature a hexagonal middle section to facilitate easier tightening with wrenches. This product meets industrial standards for precise thread cutting and dimensional accuracy, ensuring leak-proof performance in fluid handling systems.

Country Of Origin: India
A brass close nipple is a short, threaded pipe fitting used to connect two female threads in close proximity. Here are the typical sizes available:
Standard Sizes for Brass Close Nipple
Close nipples are usually specified by:
Nominal Pipe Size (NPS) – The diameter designation
Thread Type – Typically NPT (National Pipe Taper) or BSP (British Standard Pipe)
Common Sizes (NPT Threads)
Size (inches) Threads Per Inch (TPI) Approx. Length (inches)
1/8" 27 ~0.5"
1/4" 18 ~0.6"
3/8" 18 ~0.7"
1/2" 14 ~0.8"
3/4" 14 ~1.0"
1" 11.5 ~1.2"
Other Variations
BSP (British Standard Pipe) Threads – May have different TPI (e.g., 1/2" BSP is 14 TPI but with a different thread angle).
Hex Close Nipple – Some have a hexagonal middle for easier tightening.
Different Materials – While brass is common, stainless steel, galvanized, or black iron versions also exist.
