Aerospace Flexible Hoses

220 Series
RA170 (220 Series) is a lightweight 3000psi (207 bar) non-metallic aerospace hose assembly qualified to AS1975. The hose consists of an extruded smoothbore conductive PTFE innercore, reinforced with Kevlar® braid and covered by an integral Cordura® chafe sleeve. PTFE provides excellent chemical resistance and unlimited shelf life. RA170 is ideal for weight-critical 3000 PSI (207 Bar) applications within the temperature range of -65° to +275°F (-54°C to +135°C). Fire protection is available per AS1055 Class A with slip-on AS1072 firesleeve. Hybrid assemblies combining flex hose with multi-bend tube are a Titeflex specialty and provide improved vibration dampening, ease of installation, and maintenance over strictly rigid tube.
