304 Stainless Steel Extension Nipple – Threaded Pipe Fitting for Extension & Connection

Our 304 Stainless Steel Extension Nipple is a precision-engineered pipe fitting designed to extend pipe runs or connect two female-threaded pipes or fittings within a piping system. Manufactured from high-quality 304 stainless steel, this nipple offers excellent corrosion resistance, reliable threaded connections, and long service life across a wide range of plumbing, industrial, and commercial applications.

The fitting features male NPT (National Pipe Taper) threads on both ends, ensuring leak-proof seals when properly installed. The hexagonal body design provides increased leverage for installation and removal using standard wrenches .

Key Features & Benefits

• Male NPT Threads on Both Ends: Tapered threads create tighter, leak-resistant seals than straight threads, compliant with ASME B1.20.1 standards

• Hexagonal Body Profile: Provides convenient wrench flats for secure installation and disassembly without damaging threads

• Schedule 40 Wall Thickness: Standard industrial wall thickness offering balanced strength and flow capacity
