16FFS-10MFS STRAIGHT

Description & Features

A straight hydraulic fitting from Brennan Industries, the 16FFS-10MFS Straight is a two-piece assembly designed to connect a 1-inch OD tube on one end to a 5/8-inch OD tube on the other. The larger end carries a 1-7/16-12 thread, while the smaller end uses a 1-14 thread, a configuration suited to reducing connections in hydraulic lines where tube sizes transition between components. The 1.625-inch hex and 1.260-inch overall length make it compact while remaining practical to install with standard tooling.

Part of the Brennan FS2406 series, this fitting is built for reliable performance in hydraulic systems where a straight, male-to-male connection is required across differing tube sizes. The two-piece assembly design supports secure, leak-resistant joints in demanding industrial applications.
