Fuel, coolant, lubricant and hydraulic lines in vehicles, ships, aircraft and space systems must be light, flexible and extremely pressure-resistant at the same time, while carrying fuels, gases and aggressive chemicals safely. Heavy rubber hose and rigid metal tube both have limits in these installations. JINGCHENG's PTFE Steel Wire Spiral Wound Braided Hose (series JCC-03100-PTFE) solves this. An inner PTFE straight tube is reinforced with one or two layers of copper-plated steel wire winding and an outer 304 stainless steel braid, delivering lightweight construction, flexible bending and very high pressure ratings from -65°C to +220°C.
In transport, hydraulic and aerospace systems, a hose failure can stop equipment or create a safety hazard. Common failure modes include:
Pressure and pulsation: pumps and actuators create high pressure and pressure surges that fatigue weak hose walls
Chemical and fuel attack: fuels, strong acids, strong alkalis and organic solvents degrade rubber and many plastics
Weight and space limits: heavy hose adds mass and is hard to route in compact engine bays and airframes
Vibration: engines, pumps and moving structures wear out rigid lines and poorly reinforced hose
A spiral wound braided PTFE hose combines PTFE's chemical resistance with steel wire winding and stainless steel braid for high pressure capacity in a light, flexible hose.
The JCC-03100-PTFE hose uses an inner PTFE (Teflon) straight tube that is light in weight and offers flexible bending performance. The middle layer is reinforced with one or two layers of copper-plated steel wire winding, which carries the main pressure load. The outer layer is a 304 stainless steel braided wire that adds strength and protects the winding. Four catalog sizes cover 1/2" to 1" ID.
Temperature range: -65°C to +220°C
Very high working pressure: up to 44 MPa (6394.5 psi on the 1/2" size), depending on diameter
Very high burst pressure: up to 176.4 MPa (1/2" size)
Transmission media: fuel, gas, strong acids, strong alkalis and various organic solvents
Lightweight and flexible: PTFE straight tube with good bending performance
Certifications listed for this series: ISO 9001:2015, US FDA 21 CFR 177.1550 and SGS
The catalog lists this hose for the transmission of various hazardous chemicals, fuel, coolant and lubricant delivery pipelines, hydraulic machinery, trains, automobiles, ships, airplanes, rockets, spacecraft, satellites and other pipelines. Typical uses include:
Hazardous chemical transfer: strong acids, strong alkalis and organic solvents in chemical plants and laboratories
Fuel, coolant and lubricant lines: delivery pipelines on engines, generators and power units
Hydraulic machinery: high-pressure hydraulic lines on industrial and mobile equipment
Rail, automotive and marine: fuel, coolant, lubrication and hydraulic lines on trains, automobiles and ships
Aviation and aerospace: fluid lines on airplanes, rockets, spacecraft and satellites where light weight and reliability matter
Very high pressure rating. Copper-plated steel wire winding plus 304 braid; the 1/2" size is rated at 44 MPa working / 176.4 MPa burst.
High ratings even at 1". The 1" size is still rated at 27 MPa working / 108.1 MPa burst.
Lightweight and flexible. The PTFE straight tube keeps the hose light and easy to bend for compact routing.
Broad media compatibility. Suitable for fuel, gas, strong acids, strong alkalis and organic solvents.
Wide temperature window. From -65°C to +220°C for cold environments and hot engine or process zones.
Four standard sizes. From 1/2" to 1" ID, with production to customer parameters on request.

Braid-only PTFE hoses are flexible and well suited to general high-pressure lines. Adding one or two layers of copper-plated steel wire winding under the braid raises pressure capacity, so the spiral wound hose keeps very high working and burst pressures in 1/2" to 1" sizes.
Rubber hose is economical, but fuels, strong acids, alkalis and solvents can swell or harden it, and it adds weight. The PTFE inner tube is chemically inert and lightweight, making it a better fit for fuel, chemical and aerospace lines.
Rigid tubing needs precise bending and transmits vibration. A flexible spiral wound PTFE hose absorbs movement and vibration and is easier to route around engines, frames and equipment.
Pressure: keep system pressure, including surges, within the working pressure for the selected size.
Bend radius: route the hose so that bends do not go below the minimum bend radius listed above.
Temperature: confirm that fluid and ambient temperatures stay within -65°C to +220°C.
Media: the hose is suitable for fuel, gas, strong acids, strong alkalis and organic solvents. Send us your media list for confirmation in critical services.
Connection: tell us your fitting type (thread, flange, quick coupling or swage) so we can recommend the right end design.
JINGCHENG can produce the hose to customer parameters: special diameters, one or two winding layers, cut lengths, end fittings and packaging for vehicle, marine, hydraulic and aerospace equipment builders and distributors. Send us your drawings or requirements and our engineers will recommend a suitable solution.
Do not twist the hose during installation; align the ends before tightening the fittings.
Respect the minimum bend radius and avoid sharp bends right next to the fittings.
Clamp or support the hose so it does not rub against vibrating parts or sharp edges.
Keep fuel and hydraulic lines away from exhaust and other heat sources above the rated temperature.
Inspect regularly for braid damage, deformation or leakage near the connections, and replace the hose if needed.
