Stanley Aviation Sierracin Harrison
Stanley Aviation Sierracin-Harrison offers a comprehensive line of hydraulic high pressure fittings for commercial and military fixed-wing aircraft, and also helicopters, satellites, and land vehicles.
Harrison Hydraulic Fitting
In 2003, Stanley Aviation completed the acquisition of the Harrison division of the Sierracin Corporation, and subsequently became part of the Eaton corporation. Harrison does complete research, development, and production operation for high-pressure hydraulic fittings, serving as a unique industrial resource in the manufacture of high technology products for such diverse markets as aircraft, missiles, satellites, and land vehicles.
Sierracin Harrison also manufactures and provides tooling that ensures the proper installation of fittings on all types of tubing. Herber Aircraft Service can supply you with internally and externally swaged hydraulic fittings and also the tooling.
Internally Swaged Hydraulic Fittings
Sierracin Harrison has internally swaged hydraulic fittings that are mechanically fastened on the ends of removable (non-permanent) tube assemblies. These tube assemblies are used in hydraulic and high-pressure pneumatic applications. Internal Swage fittings are attached to the end of tubes by either elastomeric or roller swaging and include sleeves, unions, nuts, and bulkheads. They come in 2-groove and 3-groove versions and can be manufactured from CRES, titanium, aluminum, and other exotic metals.
SierraSwage™ externally swaged Hydraulic Fittings
These fittings are used in permanent applications to join two or more tube assemblies in similar systems. This type of fitting allows in-aircraft installation of straight "shape fittings" such as elbows and tees. The SierraSwage™ fittings are available in CRES, titanium and aluminum, and they can attain sealing pressures of up to 5,000 psi.
Herber also provides a complete line of portable, semi-automatic, and fully automatic swage machines. Portable hand swage tools are used for tube repair, low to medium volume production of tube assemblies, and experimental/prototype operations. Semi-automatic and fully automatic swage machines are designed for high-volume manufacturing. They come housed in mobile steel carts that attach fuel, hydraulic, and pneumatic fittings to CRES, aluminum or annealed titanium tubing in sizes from ¼ inch to 4 inches in diameter.
