Danfoss / Eaton STC MNPT X FM STC

Description & Features

Constructed from carbon steel with Dura-Kote plating, this 3/4 inch NPTF male to 3/4 inch female STC straight adapter is built for reliable performance in demanding hydraulic systems. The Dura-Kote finish provides superior corrosion resistance, extending service life in harsh or high-cycle environments. The adapter is rated for operating pressures above SAE standards, making it a capable choice where higher-pressure requirements exceed conventional fitting specifications.

The Danfoss / Eaton STC MNPT X FM STC belongs to the Aeroquip FF3089 Series, which offers hundreds of configuration styles to support broad design flexibility across hydraulic circuit layouts. With a minimum working temperature of -40°F, it maintains integrity in cold-temperature applications. The straight adapter configuration suits inline connections where thread-to-STC transitions are required without angular offset.

If it's got that Dura-Kote, does that mean it'll hold up okay outside?

Dura-Kote plating does give this adapter superior corrosion resistance, which should help it last longer, even in harsher environments.
