The TITEFLEX R157 (660 Series) hose assembly is qualified under several standards including SAE AS604, TSO C75 Type IIIB-S/P-F, and AS1055 Type IIa & IIb, Class A & B for integral and slip-on firesleeve.

Description:
The R157 (660 Series) is a robust aerospace hose assembly designed for 3000 psi (207 bar) applications. It features an extruded smoothbore PTFE inner core, reinforced with multiple layers of CRES 304 wire braid. The conductive PTFE inner core offers excellent chemical resistance across a temperature range of -65°F to +400°F (-54°C to +204°C) and has an unlimited shelf life. This series is ideal for applications with significant impulsing and outputs from hydraulic or pneumatic pumps. Standard fittings are made of CRES, with titanium options available. Fire protection is provided per AS1055 Class A & B, either as integral or slip-on AS1072 firesleeve. Chafe sleeves are available in various materials, and hybrid assemblies combining flex hose with multi-bend tube are offered for improved vibration dampening and ease of installation and maintenance.

Specifications:
The document provides detailed specifications for different hose sizes, including operating pressure, hose ID and OD, weight, bend radius, proof pressure, and burst pressures at room and high temperatures. For example, a size 4 hose has an operating pressure of 3,000 psi, a minimum hose ID of 0.2240 inches, and a minimum bend radius of 3.000 inches.
