Constructed from stainless steel, this Eaton Aeroquip 2021 Series Male Connector transitions between SAE 37° flare and NPTF male connections in a straight adapter configuration. It is rated for use across hydraulic, instrumentation, and chemical processing systems, where corrosion resistance and reliable sealing under pressure are consistent requirements.
Dura-Kote plating provides an additional layer of corrosion protection suited to demanding service environments. The fitting meets SAE, ASA, and ASME certification standards and is engineered to support operating pressures above standard SAE thresholds. A minimum working temperature rating of -65°F extends its suitability to low-temperature applications. As part of the broad Aeroquip straight adapter range, it offers compatibility across a wide variety of connection configurations.

Question by: Judy H on Dec 26, 2025, 6:01 AM
got a stainless line with a 37 degree flare on it, is this the fitting that’ll let me go over to NPTF?
Answer by: Customer Support on Dec 27, 2025, 7:49 AM
It’s a straight adapter built for that exact kind of transition. The item type is SAE 37 male on one end and NPTF male on the other, and the body material is stainless steel.
