DANFOSS / EATON ADAPTERS

Description & Features

Designed as a 45° elbow configuration, this carbon steel adapter connects a 1-inch SAE split flange (Code 62) end to a 1-inch SAE 37° male flare, making it well-suited for hydraulic systems in demanding environments such as marine, military, offshore drilling, chemical processing, and food and beverage or pulp and paper facilities. The flanged-to-flare geometry accommodates routing changes where straight fittings are not practical.

Part of the Eaton Aeroquip Danfoss / Eaton Adapters FF5539 series, this fitting features Dura-Kote plating for corrosion resistance across a broad operating temperature range, with a minimum rated working temperature of -65°F. The series is built to exceed standard SAE pressure thresholds and is certified to SAE J514. With hundreds of styles available across the product line, it supports broad design flexibility for complex hydraulic circuit configurations across industrial and specialty applications.

Question by: Harvey C on Oct 16, 2025, 2:13 PM

What's the temperature range on this Eaton adapter?

Answer by: Customer Support on Oct 18, 2025, 9:09 AM

This adapter is rated to handle minimum working temperatures down to -65°F, so it should hold up even in pretty cold conditions.

Got a tight routing situation on a hydraulic line and can't run straight through, does this fitting actually change direction, or is it more of a straight adapter with a slight offset?

Answer by: Customer Support on Oct 16, 2025, 9:37 PM

A 45-degree elbow is what you're getting here, so it does give you a real directional change, not just a minor offset. One end connects to a 1-inch SAE split flange using Code 62 flanged geometry, and the other end is a 1-inch SAE 37-degree male flare. That combination lets you transition between a flanged connection and a flared fitting while also changing the line direction, which is exactly what comes in handy when you're working in tight or congested areas where a straight adapter just won't get the job done.

Question by: Lee C on Jun 16, 2025, 6:53 AM

got a tight spot on a hydraulic line, is this the kind of fitting that lets you turn the run without going straight out?

Answer by: Customer Support on Jun 17, 2025, 3:37 PM

For routing changes where a straight fitting will not work, the 45 degree elbow layout gives you a turn while still adapting between a 1 inch SAE split flange end (Code 62) and a 1 inch SAE 37 degree male flare.
