Excellent Customized Low Pressure Resistant Convoluted Ptfe Bellow Hose

PTFE (F4),due to its excellent dielectric properties and chemical resistance, properties of water repellet, non-stick,non-conductive,low friction coefficent and non-aging,generally connected with flange,union connection fittings,threaded,quick connector, as well as connect with the pipe directly,fixed by pipe strap or wire,widely used in chemical,petroleum,
pharmaceutical etc.

Excellent Customized Low Pressure Resistant Convoluted Ptfe Bellow Hose
Polytetrafluoroethylene (PTFE) bellow hose is an engineered fluoropolymer.Outstanding resistance to chemicals is one of ptfe hose's primary attributes. 

A broad temperature range of -100℃ to 180℃ makes this convoluted ptfe hose mateirals suitable for the majority of fluids and ambient temperature conditions sound in most industries.With all types of ptfe bellow hose,increased working temperatures require a reduction in maximum rated working or burst pressure. Whenever excessive flexing,vibration,thermal fluctuations or rapid pressure impulsing is in evidence,further caution should be exercised in reducing the maximum working pressure. 

An extremely low coefficient of friction provides a non-stick surface.Water absorption of PTFE is negligible.and it is approved for food and pharmaceutical use. 

Additionally,convoluted PTFE hose will withstand flexing and vibration without failure from flex fatigue.PTFE bellow hose is chemically inert.It will not break down or deteriorate in service,and it has an unlimited shelf life because properties do not change with age or exposure to weather. Low pressure resistant PTFE hose can be used in aerospace,automotive,chemical and industrial applications. 

Fustar offers convoluted PTFE bellow hose in a variety of configurations.PTFE hose innercore is offered in smooth bore,convoluted,

smooth inner with a convoluted outer,conductive anti-static and non-conductive virgin.Type 304 or 316 stainless steel wire braid is the standard reinforcement with other specialty materials available.

Fustar can offer alternative PTFE hose covers for chafe resistance and silicone-covered hose for heat and fire resistance.Alternate braid materials include braided convoluted PTFE hose and braided high-pressure smoothbore PTFE hose. 

All stated burst pressure are static and are measured on samples at ambient temperature from which averages are recorded to create relevant specifications.Proof or test pressures are usually twice working pressure.All burst pressures are conservatively rated to provide a high margin of safety.Fustar 100% tests all assemblies.
