10FFSS-12MJ STRAIGHT

Description & Features

A straight face seal fitting designed for connecting 3/4 inch OD tube (JIC male) to a 5/8 inch OD tube (female face seal) end, the 10FFSS-12MJ Straight from Brennan Industries is built for reliable performance in hydraulic line connections where leak-free face seal integrity is required. The straight configuration simplifies in-line routing where directional changes are not needed.

Thread sizes are 1-1/16-12 on the male JIC end and 1-14 on the female face seal end, with a hex dimension of 1.125 inches on both ends and an overall length of 2.354 inches. Part of Brennan's FS6504 series, this fitting is suited for medium- to high-pressure hydraulic systems where a secure metal-to-metal seal is essential.
