Flexible Hose
Polytetrafluoroethylene (PTFE) is an engineered fluoropolymer. Oustanding resistance to chemicals is one of its primary attributes. A broad temperature range of -67°F to 400°F (-55°C to 204°C) make this hose material suitable for the majority of fluid and ambient temperature conditions found in industry. An extremely low coefficient of friction (0.05 to 0.20) provides a non-stick surface. Water absorption of PTFE is negligible, less than 0.01% by ASTM test. Additionally, PTFE will withstand flexing and vibration without failure from flex fatigue. PTFE is chemically inert; it will not break down or deteriorate in service and has an unlimited shelf life because age and exposure to weather do not change its properties.
Titeflex offers PTFE hose in a variety of configurations. Titeflex PTFE hose innercore is offered in smooth bore and convoluted, conductive (carbon black added) and non-conductive. Type 304 stainless steel wire braid is the standard reinforcement with other specialty materials available. Titeflex offers sleeves for chafe resistance and silicone-covered hose for heat and fire-resistance. Alternate braid materials include Nomex braided convoluted hose and Kevlar braided high-pressure smooth bore hose.

Smooth Bore
As the innovator in PTFE hose technology, Titeflex has pioneered the production and utilization of smooth bore PTFE hose throughout a wide spectrum of demanding aerospace applications. The first to produce extruded PTFE hose in 1955, Titeflex remains the leader in smooth bore PTFE extrusion. Titeflex smoothbore PTFE hose innercore is vertically extruded to maintain the highest quality of concentricity and is manufactured from Dupont type 62 fine grade resin or equivalent with type 304 stainless steel wire braid reinforcement. Titeflex smooth bore innercore is available in both conductive and non-conductive configurations.
Convoluted
Titeflex began production of convoluted PTFE hose in 1965, and remains a leader in this lightweight and flexible hose. Titeflex convoluted PTFE hose consists of PTFE tape externally reinforced with PTFE impregnated fiberglass and type 304 stainless steel wire braid. The tube is convoluted in a forming die and then heated to bond the layers. Titeflex convoluted innercore is available in both conductive and non-conductive configurations.
Annular Convoluted Flexible Metal Hose
Titeflex convoluted metal hose is the premier and proven all-metallic aerospace hose, qualified to AS1424. It performs in extreme hot and cold, beyond the range of all thermoplastic hoses. It is used extensively on space vehicle and launch vehicle applications as well as hot sections of turbine engines where performance and reliability are critical. Titeflex can mold a proprietary silicone on these hose assemblies, encapsulating braid and innercore, for service in severe vibration applications.
