MALE PIPE X MALE PIPE HEX NIPPLE

Description & Features

Constructed from straight steel, this 2-1/2-8 Male Pipe x Male Pipe Hex Nipple provides a double-ended male NPTF connection for joining two female-threaded fittings in a single inline assembly. Both threaded ends conform to SAE J476, making it suitable for hydraulic and industrial fluid systems where a secure, pressure-resistant pipe connection is required.

The hex body allows for standard wrench engagement during installation and removal, simplifying assembly in tight or high-torque applications. At approximately 3.95 inches in overall length, this Brennan Industries Series 5404 fitting is well-suited for close-coupled connection points where space is a consideration.
