20FFS-12MFS ST

Description & Features

A straight hydraulic fitting designed for reducing applications, the 20FFS-12MFS ST connects a 1-1/4" OD tube on one end to a 3/4" OD tube on the other, using 1-11/16-12 and 1-3/16-12 male face seal threads respectively. The two-piece assembly from Brennan Industries belongs to the FS2406 series and is built to handle the thread engagement and sealing demands typical of face seal hydraulic connections.

With an overall length of 1.320" and a 1.875" hex, the fitting is compact while still providing adequate wrench access for installation in tight hydraulic assemblies. The 0.609" A2 drill dimension is consistent with the 3/4" port side of the fitting. This part is well-suited for hydraulic circuits requiring a straight, inline reduction between two different tube sizes.
