Danfoss / Eaton Weatherhead 691X4 90° Male Elbow Male 7/16-24 Line/Hose/Tube Male 1/8-27 NPTF Brass

Description & Features

A brass 90° elbow adapter designed for instrumentation, hydraulic, and pneumatic systems, the Danfoss / Eaton Weatherhead 691X4 90° Male Elbow Male 7/16-24 Line/Hose/Tube Male 1/8-27 NPTF Brass connects a 1/8-27 NPTF male thread to a 7/16-24 male line/hose/tube end at a right angle. The brass construction provides reliable performance across a wide temperature range, rated down to -65°F minimum.

Part of Eaton Aeroquip's elbow adapter line, this fitting features Dura-Kote plating for corrosion resistance and is built to handle operating pressures above SAE standards. The 90° orientation makes it well suited for routing in space-constrained assemblies where a straight adapter would not fit. With a hex size of 0.500 in. on the line/hose/tube end, installation is straightforward with standard tooling.

Product Questions & Answers (2)

Question by: Rusty B on May 5, 2025, 6:06 AM
Will this brass elbow hold up okay in a hydraulic system, or is it more for like, air lines and stuff?
Answer by: Customer Support on May 6, 2025, 6:06 AM
Brass construction makes this 90-degree elbow adapter suitable for both instrumentation and hydraulic/pneumatic systems.
Question by: Chad H on Jun 10, 2025, 10:26 AM
does this fitting work for both hydraulic and pneumatic lines, or is it just one or the other?
Answer by: Customer Support on Jun 11, 2025, 5:25 PM
Rated for both hydraulic and pneumatic systems, so you're not limited to one application. It also covers instrumentation setups, which makes it a solid pick when you're working across different line types on the same job.
