PTFE hose/Teflon hose have two kind tube, one is Smooth tube, another is Corrugated tube, please see below detail introduction:

Smooth Bore PTFE Hose With Braids

PTFE Hose is a smooth bore PTFE hose with a stainless steel braiding, available up to 2" diameters. The diameters listed reflect nominal sizing.It is lightweight, and handles a very broad range of chemicals atrelatively high temperatures and pressures, and will not deteriorate in service. It is used in countless tough industrial applications where continual large bending is not required.Commonly provided with JIC, NPT or many other fittings.

Also available with a convoluted PTFE core for tighter bends.

Corrugated PTFE Hose With Braids

PTFE Hose is a convoluted PTFE hose with a stainless steel braiding, available up to 4" diameters.The convolutions provide a far tighter bend radius than most smooth bore alternatives.It is lightweight, and handles a very broad range of chemicals at relatively high temperatures and pressures, including full vacuum It is used in countless tough industrial applications where a smooth bore is not required.Also available in conductive PTFE.Commonly provided with JIC, NPT or many other fittings.

Construction:

• Tube: smooth bore or Corrugated PTFE
• Shape of hose: Smooth bore or corrugated
• Cover: SS304/SS316 Braided
• Temperature:-65℃ to +260℃

Application:

• Mainly used for conveying various chemicals, ships, automobiles, Marine industry machinery hydraulic system etc.
• Coil length:10m-200m(Random Length).
• Standard: SAE100 R14
• Connector: JIC,NPT,BSP Fitting, flange etc.The middle layers viscosity-strengthen
• rubber between reinforcements to provide high dynamic capability

• High temperature resistance-the highest temperature up to 250 degrees.
• Low temperature resistance-has good mechanical toughness,-54 degrees can also
• maintain 5% elongation.
• Excellent anti-sticking--it is not easy to adhere any substance on the inner wall of the tube.
• Resistance to strong alkalis-Almost good inertness to almost all chemicals and solvents.Climate resistance-excellent aging resistance, can be used outdoors for a long time.
• Excellent electrical insulation performance: the dielectric constant is about 2.0, Class C electrical insulation material.
