Description & Features

A carbon steel straight adapter connecting 1/8" NPTF male to 3/4" SAE 37° male (JIC) threads, the Danfoss / Eaton Adpt 1/8 Mp 8 Mjic is part of the Eaton Aeroquip 2021 Series and is certified to SAE 070102. Its straight configuration suits inline connections where both thread types need to interface without angle offset.

Dura-Kote plating provides corrosion resistance suited to demanding service environments, including marine, military, offshore drilling, chemical processing, food and beverage, and pulp and paper applications. The adapter is rated for a minimum working temperature of -40°F and is engineered to support operating pressures above standard SAE thresholds. With hundreds of available styles in the 2021 Series, design flexibility is maintained across a wide range of system configurations.

trying to swap out an old fitting, is this one the straight adapter that goes from 1/8 NPTF male to a 37 degree flare male?
Answer by: Customer Support on Jun 14, 2025, 6:16 AM
it is a straight adapter with a 1/8 in NPTF male on one end and an SAE 37 degree male flare on the other. It is listed as an NPTF Male to SAE 37 degree Male straight adapter.
Question by: Brett R on Mar 8, 2026, 2:31 PM
what industries is this adapter rated for? got some chemical processing lines and want to make sure it'll hold up before I order a bunch
Answer by: Customer Support on Mar 10, 2026, 6:07 AM
Carbon steel construction with Dura-Kote plating gives this fitting solid corrosion resistance, and it carries certifications under SAE 070102. Chemical processing is one of the listed application areas, along with marine, military, pulp and paper, food and beverage, and offshore drilling. That covers a pretty wide range of demanding environments, so chemical line use fits squarely within what this adapter is built for.
