1/4" Male NPT X 4" Long Pipe Nipple 3" Extension Threaded Fitting Brass

1/4" Male NPT x 4" Long Brass Pipe Extension Nipple

This brass pipe nipple features two 1/4" male NPT (MNPT) threaded ends and measures 4 inches in total length. While the overall length is 4", the actual extension between the threads — the unthreaded middle portion — is 3" in length, providing a 3" extension between connections when installed. This can fluctuate slightly based on how far the connections are threaded together during installation.

Constructed from durable, corrosion-resistant yellow brass, this fitting is well-suited for water, air, gas, oil, and other non-corrosive fluids or media. This fitting is compatible with brass, bronze, copper, steel, aluminum, and iron pipe systems. Made of durable brass, it offers fair vibration resistance and a broad operating temperature range.
