TITEFLEX R270 (510 Series) SERIES QUALIFICATIONS Qualified to numerous aerospace application specific requirements. DESCRIPTION R270 (510 Series): low-pressure PTFE hose with non-metallic braid for specialized aerospace applications. The hose consists of convoluted (tape wrap) PTFE innercore, similar to the 410 Series, except the 510 Series is reinforced with a braid of Nomex© instead of CRES. This construction provides an exceptionally tight bend radius, and light weight. Standard fittings are aluminum. Operating pressures range from 300 PSI (21 Bar) in the smaller diameters to 200 PSI (14 Bar) in the larger diameters. Fire protection is available with AS1055 Class A slip-on AS1072 firesleeve. Popular applications for the R270 (510 Series) include breathing oxygen, and electronic cooling fluids. 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.
