Ask A Question

Description & Features

Rated to 3,000 PSI dynamic pressure, this straight steel hex nipple connects 1-11½ Male Nptf (SAE J476) on one end to 3/8-18 Male Nptf (SAE J476) on the other, making it a reliable reducer fitting for hydraulic lines requiring a transition between these two thread sizes. The hex body provides a secure wrench grip during installation and removal.

The 16Mp-06Mp Hex Nipple is manufactured from straight steel and belongs to Brennan's 5404 Series. Both thread ends conform to SAE J476, ensuring compatibility with standard Nptf fittings used across industrial hydraulic systems. At an overall length of 1.960 mm, the compact profile suits tight-clearance installations where space is limited.

Question by: Roy R on Dec 28, 2025, 7:14 AM
Will this here fitting hold up okay for a hydraulic system runnin' around 2800 PSI?
Answer by: Customer Support on Dec 30, 2025, 6:33 AM
This straight steel hex nipple is rated to handle dynamic pressures up to 3,000 PSI, so it should work fine in a hydraulic system with 2800 PSI.
