Brass Hexagon Nipple M X M - 3/8"

Brass Hexagon Nipple M X M - 3/8"

The 3/8" Brass Hexagon Nipple is a precision-threaded fitting used to join two female-threaded components of the same size. This fitting is a staple in oil-fired heating systems, compressed air lines, and specialized plumbing where a compact, high-pressure connection is required.

Featuring a hexagonal center, this nipple allows for a secure grip with a spanner or wrench, ensuring you can apply the necessary torque to create a gastight or watertight seal without damaging the threads.
