Constructed from stainless steel, this straight adapter is built for hydraulic, instrumentation, and chemical processing systems where corrosion resistance and reliable sealing are essential. It features an NPT end (3/8 in.) on one side and an NPTF end (3/4 in.) on the other, providing a straight male-to-male connection between differing thread sizes. Dura-Kote plating adds a further layer of corrosion protection suited to demanding service environments. The Male Connector is part of the Danfoss Power Solutions (Aeroquip) 2021 Series, which covers hundreds of adapter styles, supporting broad configuration flexibility across system designs. Operating pressures exceed SAE standards, and the working temperature range extends down to -65°F. Certified to ASA, ASME, and SAE standards, this fitting is a dependable choice for industrial fluid power applications.
