Extruded Fittings
All BrassCraft extruded fittings are shaped from a single piece of bar stock by 22 different machining operations. The result is a one-piece, solid brass fitting without seams or brazed joints.

To create each fitting, bar stock is extruded into the required configuration. Then it’s drawn to size, straightened and cut to length. This process involves heating a solid round billet (8 to 12 inches in diameter) to the pliable state and forcing it with 80,000 pounds per square inch of pressure through a die. Next, the formed bar is cooled and drawn through dies to the desired external size, straightened, and then cut to length.

This BrassCraft Mfg extrusion process produces a fitting’s material that’s dense, nonporous and stronger in its longitudinal direction.

Forged Fittings
To produce forged fittings, material is extruded into round bars, cut to length and straightened, creating forging rod that differs from extruded machinable bars in its temper and chemical composition. Then the bars are cut again into short-length slugs, reheated to the pliable state and pressed between dies under 25,000 pounds per square inch pressure. Next, they are cooled, the flash is trimmed and the forging blank is machined into its finished form.

Forming fittings under extreme pressure produces a uniformly dense material with high impact strength and resistance to mechanical shock and vibration.
