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

Description & Features

A straight union adapter from Eaton Aeroquip's 2027 Series, the Steel Adapter, 1-5/8-12 Male JIC 37 deg Flare To 1-5/8-12 Male JIC 37 deg Flare, Straight connects two male JIC 37° flare ends of the same thread size in a single, in-line fitting. Both connection ends carry a 1-5/8-12 thread, and the overall assembly length measures 2.43 inches.

Constructed in steel, this union adapter is suited for hydraulic, instrumentation, and chemical processing systems where a same-size, same-standard inline connection is required. The 37° flare seating geometry provides a reliable metal-to-metal seal consistent with SAE J514 JIC standards. Its straight configuration makes it a practical choice for rejoining or extending lines without introducing a change in direction or thread type.

Question by: Diane E on Aug 21, 2025, 12:00 PM
i’ve got two lines that are both 1-5/8-12 JIC, is this basically just a straight union to tie em together?
Answer by: Customer Support on Aug 23, 2025, 7:38 AM
Function-wise, it is a straight union adapter that connects a 1-5/8-12 male JIC 37 degree flare on one side to a 1-5/8-12 male JIC 37 degree flare on the other, so it’s meant for joining two matching JIC 37 flare connections in-line.
