Description & Features

A straight male pipe to female face seal adapter from Brennan Industries, the FS6505-20-20 connects a 1-1/4-11-1/2 male NPT thread to a 1-11/16-12 female face seal port in a single inline configuration. With a 1-1/4 in. tube OD rating, this adapter is suited for high-pressure hydraulic line connections where a leak-free face seal termination is required on one end and a tapered pipe thread on the other.

Overall length is 2.900 in., with a 1.875 in. C hex and a 1.750 in. H hex for wrench engagement during installation. Port A has a 1.250 in. hole diameter and port B measures 1.024 in., providing clear bore geometry consistent with the Brennan FS6505 series standard.
