Aeroquip® 1,500 psi PTFE Hose and Assemblies E;T*N Powering Business Worldwide

Chemical Resistance Eaton's Aeroquip 666/667 medium pressure PTFE hose is used in hydraulic and pneumatic applications at pressures up to 1500 psi (10,342.5 kPa). The hose is unaffected by all fuels, oils, alcohols, coolants, or solvents commonly used in aircraft. In addition, it is inert to acids both concentrated and diluted. Eaton's non-conductive version (AE116) is suitable for oxidizers and propellents used in the missile field. The PTFE liner has sufficient conductivity to prevent electrostatically induced hose failures. The tube is capable of conducting a direct current equal to or...

Compression Crimp Fittings For Use With Aeroquip 666/667 Medium Pressure PTFE Hose Compression crimp fittings are available in both flared and flareless types to mate with (AS4395) and (AS4375) end connections. In addition, elbow fittings are available in standard 45° and 90° styles. Special elbows, crosses, tees, wyes, adapters, bosses, etc. may be made for customer installations. The unique combination of the ramped nipple and the crimping pattern used on the compression crimp fitting results in superior fitting retention under pressure. Burst pressure tests indicate that extreme...

Basic Assembly Numbers The basic part number shown here represents standard configurations with materials, markings, and cleaning requirements confirming to MIL-DTL-25579. If your requirements differ from these standards, the hose assemblies you order will be assigned new number by Eaton. Hose Letter Code Rotational Angle Measurement On assemblies with an elbow fitting on each end, measure the position angle as shown above and suffix the angle to the basic style number. In all cases, the angle should be expressed in 3 digits. For example, 35° should be written as 035. If the angle desired...

In Accordance with MIL-DTL-27272 The "super gem"fitting provides permanent protection against leakage, even after high temperature aging and impulsing. The reason for this performance lies in the separation of the sealing function from the retention function. A lip seal is formed by the separation of the PTFE tube in an annular chamber, while positive grip on the wire reinforcement between socket and nipple sleeve provides permanent protection against fitting blow-off. Adjustable Elbows "super gem"adjustable elbow fittings are easily positioned through 360° to the desired relative angle...
