Constructed from brass, this 3/8 in. straight-through coupler is designed for industrial fluid line connections requiring a male NPT threaded interface. The straight-through configuration allows unrestricted flow without internal valving, making it well-suited for applications where full flow passage and minimal pressure drop are priorities.
The 3/8 Straight Thru Cplr, 3/8 MNPTF Brass from Dixon Valve & Co features male NPTF threading, which provides a dry-seal connection that relies on thread interference rather than a separate sealant for leak resistance. Brass construction offers good corrosion resistance and compatibility with a range of hydraulic and pneumatic media commonly found in industrial environments.

Reckon this'll hold up alright with hydraulic oil? Don't wanna use somethin' that'll just eat away.

Brass offers good corrosion resistance and is generally compatible with hydraulic and pneumatic media, so it should work well for hydraulic oil applications.
