Product Questions & Answers

got a line that’s 1/4 npt on one side and a 4 mjic on the other, is this the right straight adapter?

Question by: Shawn A on May 16, 2025, 8:38 AM

Function-wise, it’s a straight adapter meant to connect a 1/4 inch male NPT end to a 4 MJIC (37 degree flare) male end. It’s part of the Danfoss Eaton 2021 Series straight adapters.

Application-wise, this adapter is certainly suitable for hydraulic systems. It's also designed for instrumentation and chemical processing, so farm equipment should be well within its capabilities.
