Steel Adapter, 1-5/8-12 Female JIC 37 deg Flare Swivel To 1-5/16-12 Male JIC 37 deg Flare, Straight

Description & Features

Part of the Danfoss Power Solutions (Aeroquip) 221501 Series, this fitting connects a 1-5/8-12 female JIC 37° flare swivel end to a 1-5/16-12 male JIC 37° flare end in a straight configuration. Both ends use SAE 37° flare seating, providing a reliable metal-to-metal seal suited for high-pressure hydraulic lines. The reducer design accommodates two different thread sizes within a single inline adapter, eliminating the need for additional fittings when transitioning between line sizes.

Constructed from steel, this adapter carries a minimum working temperature rating of -65°F, making it suitable for demanding low-temperature environments. No thread sealant is required given the flare-type sealing method. The catalog reference for this part is C1BC68, and it is classified under EAR99 for export purposes. The Steel Adapter, 1-5/8-12 Female JIC 37 deg Flare Swivel To 1-5/16-12 Male JIC 37 deg Flare, Straight is a standard component used across a range of industrial hydraulic assemblies.

i’ve got a hose end that’s 1-5/8-12 female JIC swivel, will this adapter step it down to a 1-5/16-12 male JIC and stay straight?

For stepping down JIC sizes, this part is a straight steel reducer adapter with a 1-5/8-12 female JIC 37 degree flare swivel on one end and a 1-5/16-12 male JIC 37 degree flare on the other.

Hey, I'm trying to replace an adapter on my Danfoss system. Is this the right one for a 1-5/8-12 female JIC to 1-5/16-12 male JIC connection?
Answer by: Customer Support on Oct 22, 2025, 6:11 AM
This Eaton Aeroquip adapter is indeed designed for that exact connection type. It’s a straight steel adapter going from a 1-5/8-12 Female JIC 37 deg Flare Swivel to a 1-5/16-12 Male JIC 37 deg Flare. Double-check those sizes, though, just to be sure.
