- TSO-C140 Type IaB/IIa Class B
The RM190 (190 Series) is an aerospace low-pressure smooth bore hose qualified to AS4897. It is designed to meet the aerospace industry's demand for a lightweight, low-pressure PTFE hose. The operating pressures range from 1000 PSI (69 Bar) for smaller diameters to 750 PSI (52 Bar) for larger diameters. The hose features an extruded smoothbore PTFE inner core, reinforced with a single layer of CRES 304 wire braid, offering excellent chemical resistance from -65°F to +450°F (-54°C to +232°C) with unlimited shelf life. All assemblies include AS1055 Class A & B integral firesleeve. Standard fittings are CRES, and hybrid assemblies with flex hose and multi-bend tube are available for improved vibration dampening and ease of installation.
