The Difference between Forged and Brazed Hydraulic Fittings

Air-Way is pleased to offer two manufacturing styles of hydraulic fittings, both forged and brazed. While there are similarities between the two, there are also several noteworthy differences. Below, we’ll dive deeper into what forged and brazed fittings are and how they differ.

Forged Hydraulic Fittings 

Forged hydraulic fittings and adapters are machined out of one piece of metal. Since forged fittings are one piece, they can typically be manufactured with less material, resulting in a smaller wrench flat, and ultimately a more compact design.  The general drawback of forged fittings, however, is less flexibility and increased material waste.  Forgings also require volumes that justifies the cost of the forge tooling.  As a global hydraulic fitting manufacturer, Air-Way does have a location in China, which produces forged fittings and adapters. We also keep an inventory of forged fitting blanks in our US based inventory so we can machine them to spec, when needed.

There are two main types of forging: hot forging and cold forging. While hot forging involves heating metal above its recrystallization temperature, cold forging involves heating metal at room temperature or any temperature below recrystallization.  While Air-Way does produce some components and plugs incorporating the cold forge process (cold heading), the majority of our forged adapters are hot forged.

In addition two different types of forging, there are various processes for it. These processes include:

  • Open die forging: Open die forging occurs when flat dies with no precut profiles participate in forging. 
  • Closed die forging: Also known as impression die forging, closed die forging uses molds, which are attached to an anvil while a hammer directs heated metal to flow into the die’s cavities.  
  • Press forging: During press forging, the metal sits on a stationary die while a compression die applies pressure to achieve the ideal shape. 
  • Roll forging: Roll forging focuses on increasing rods or wires in length. Heated metal bars are placed between two rotating rolls that apply continuous pressure to shape the metal. 

Adapters supplied by Air-Way Global Mfg. are processed through the closed die or press forging method.

Brazed Hydraulic Fittings & Adapters

Brazed adapters are created from multiple machined components that are combined together, resulting in a finished part. As compared to forged fittings, brazed fittings allow for more customizations with different components. Low volume solutions, as well as customizations can become cost effective using brazed adapters.  There are different processes for brazing including:

  • Torch brazing: This is the most common type of mechanized brazing, torch brazing consists of three categories: machine, manual, and automatic. 
  • Furnace brazing: Furnace brazing is widely seen in industrial environments as it can generate large amounts of parts and involves a continuous belt, with controlled atmosphere and heat cycle.
  • Silver brazing: Silver brazing uses a silver alloy based filler and is often referred to as silver soldering or hard soldering. 
  • Braze welding: Braze welding uses a bronze or brass filler rod with flux to join the pieces together. 

All brazed adapters supplied by Air-Way Global MFG. are manufactured through furnace brazing

Both forged and brazed hydraulic fittings offer advantages depending on the application requirements. Whether you’re looking for a solid forged hydraulic fitting, or need a custom hydraulic fitting to meet your exact specifications, a brazed fitting may be in order. No matter what your hydraulic application is, Air-Way delivers exceptional flexibility by offering standard and custom adapters. Both brazed and forged styles of our adapters are qualified to the same working pressures and performance standards, meeting the SAE specifications.

  • Importance of Pressure Ratings and Testing for Hydraulic Fittings

    It can be difficult to find the right hydraulic fitting or adapter. With so many options available, it can be overwhelming to choose the one that is ideal for your application. While you can simply pick one and hope for the best, we recommend paying attention to pressure ratings as pressure is one of the most important things to consider when you’re evaluating hydraulic adapters and systems.
