Description & Features

Designed for hydraulic, instrumentation, and chemical processing systems, this Eaton Aeroquip 2041 Series straight bulkhead adapter provides a reliable union connection between two 1-1/16-12 Male JIC 37° flare fittings. The bulkhead configuration allows the fitting to pass through a panel or bulkhead wall, securing fluid lines across a partition without additional hardware.

The Steel Adapter, 1-1/16-12 Male JIC 37 deg Flare To 1-1/16-12 Male JIC 37 deg Flare, Straight Bulkhead is manufactured by Eaton Aeroquip and carries catalog number C1AY40. With an overall length (A) of 3.09 inches and a panel engagement dimension (B) of 1.75 inches, it suits standard bulkhead installations where consistent thread sizing on both ends is required. The 37° flare seating provides a metal-to-metal seal suitable for medium- to high-pressure hydraulic service.
