Ask A Question

Description & Features

Designed for straight-thread to flare connections in hydraulic lines, the Danfoss / Eaton -12 Stc Male x 12 Male Jic fitting provides a reliable transition between STC (straight thread connector) and JIC 37° flare configurations. Both ports are sized at -12, making this a same-size adapter suited for applications where these two thread standards meet within a hydraulic circuit.

Manufactured under the Aeroquip brand, this fitting is built to the standards associated with Eaton's hydraulic connector line. It is a practical choice for maintenance, repair, and original equipment assembly where STC male and JIC male interfaces need to be joined without additional components.

So this is just a straight adapter, right? Both ends are the same size?
Answer by: Customer Support on Aug 3, 2025, 6:10 AM
That's correct. This Danfoss/Eaton fitting adapts a -12 STC male to a -12 male JIC, so it's the same size on both ends.
