RM 190 (190 SERIES)

Aerospace low pressure smooth bore hose qualified to AS4897. The 190 Series is designed to answer the aerospace industry’s need for a weight-saving low-pressure smooth bore PTFE hose. Operating pressures range from 1000 PSI (69 Bar) in the smaller diameters to 750 PSI (52 Bar) in the largest diameter. The hose consists of an extruded smoothbore PTFE innercore, reinforced with a single layer of CRES 304 wire braid. PTFE provides excellent chemical resistance over a temperature range of -65ºF to +450ºF (-54ºC to +232ºC) with unlimited shelf life. All 190 Series hose assemblies are furnished with AS1055 Class A & B integral firesleeve. Qualified standard fittings are CRES. 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.
