Industrial fluid systems do not always operate at one perfectly stable pressure.
A pressure gauge may show a normal working value during steady operation, but the hose can experience very different conditions when:
a pump starts,
a valve closes,
equipment changes operating mode,
a fluid circuit is pressurized,
production stops and restarts.
These events can create short-term pressure changes that are different from normal steady-state operation.
For this reason, engineers selecting a hose for pump-driven equipment should consider more than only the nominal system pressure.
The JCC-01200-PTFE double braided PTFE hose uses a smooth PTFE inner tube surrounded by two layers of high-strength 304 stainless steel braided reinforcement.
According to the catalog, the hose operates across a temperature range of approximately:
-70°C to +260°C
and is intended for hydraulic transfer involving:
gas-based fluids,
oil-based fluids,
water-based fluids,
chemical raw materials.
Its double-braid construction makes it particularly relevant where additional mechanical reinforcement is required around the PTFE fluid path.
A fluid system operating continuously at one stable condition is relatively straightforward to evaluate.
Real industrial machines are more dynamic.
Consider a pump that repeatedly starts and stops during production.
Each operating cycle may create changes in:
internal hose pressure,
flow velocity,
fitting load,
hose expansion.
Valve operation can also influence system behavior.
A rapidly changing flow condition may produce a short pressure rise before the system returns to its normal operating level.
The hose therefore needs to be selected according to the real pressure environment, not only the average reading seen during normal production.
The main structural difference in JCC-01200 is its double stainless steel braid.
The hose construction consists of:
Smooth PTFE Inner Tube + Two Layers of High-Strength 304 Stainless Steel Braid
Each part performs a different function.
The PTFE inner tube provides the material-contact path.
The stainless steel reinforcement helps control the hose mechanically under internal pressure.
Compared with a simpler single-braid structure, the double reinforcement provides another option for industrial systems requiring substantial pressure capability.
The catalog lists strong working-pressure ratings across several diameters.
Selected values include approximately:
1/4" — 40 MPa
5/16" — 35 MPa
3/8" — 32 MPa
1/2" — 27 MPa
5/8" — 21 MPa
3/4" — 20 MPa
1" — 17 MPa
1-1/4" — 14 MPa
The corresponding burst pressures are significantly higher.
However, burst pressure should never be treated as a normal working-pressure target.
The correct hose should be selected according to the required continuous pressure, transient conditions, temperature and application-specific safety requirements.
The inner tube is smooth PTFE.
This allows the hose family to serve a broad range of industrial fluid circuits.
The catalog specifically identifies applications involving:
gas-based fluids,
oil-based fluids,
water-based fluids,
chemical materials.
This is useful for equipment manufacturers that operate several different fluid circuits within the same machine or production system.
Rather than designing each circuit around a completely unrelated hose family, a manufacturer may be able to use the same double-braided PTFE construction in multiple positions while changing the diameter and fittings according to each circuit.
One important application for reinforced flexible hose is the connection near a pump discharge.
This area may experience:
pressure changes,
equipment vibration,
installation misalignment,
thermal movement.
A flexible hose can provide a transition between the pump and rigid downstream piping.
The double-braid structure supplies pressure reinforcement while the PTFE tube provides chemical compatibility for suitable process media.
Many industrial machines do not operate continuously at one speed.
Production cycles may involve:
start → pressurize → transfer → stop → restart
Examples may include:
dosing machines,
hydraulic transfer equipment,
automated processing systems,
chemical handling units,
test equipment.
For these systems, the hose should be selected around the complete operating cycle.
This includes both normal working pressure and any expected pressure changes during machine operation.
A common mistake is assuming that every diameter in the same hose family has the same pressure capability.
The JCC-01200 table shows that this is not the case.
As diameter increases, working pressure generally decreases.
For example:
A 1/4" hose is listed at approximately 40 MPa, while the 1-1/4" hose is listed at approximately 14 MPa.
This means diameter selection must balance two separate requirements:
required flow area and required pressure capability.
Increasing diameter can reduce fluid resistance, but it may also reduce the available working-pressure rating.
The same trade-off appears in mechanical routing.
The catalog lists minimum bending radii of approximately:
1/4" — 83 mm
5/16" — 83 mm
3/8" — 105 mm
1/2" — 140 mm
5/8" — 176 mm
3/4" — 210 mm
1" — 285 mm
1-1/4" — 340 mm
A larger hose therefore requires more installation space.
Machine designers should consider the available routing envelope before finalizing the diameter.
The catalog specifies approximately:
-70°C to +260°C
This allows the hose to be considered for systems involving both cold and elevated-temperature fluids.
Potential applications may include:
oil transfer,
chemical processing,
heated process fluids,
water-based industrial systems.
Pressure capability at the actual operating temperature should always be confirmed for the selected configuration.
A room-temperature pressure value should not automatically be assumed to remain identical at every temperature.
A stronger reinforced hose can still be damaged by poor installation.
Important installation practices include avoiding:
hose twisting,
bending directly behind the fitting,
bending below minimum radius,
uncontrolled abrasion,
excessive unsupported hose weight.
The hose should be routed so that the reinforcement works as intended rather than being subjected to unnecessary mechanical stress.
At high pressure, the hose body is only one part of the complete assembly.
The pressure boundary also includes:
fitting,
ferrule,
crimp area,
sealing interface,
machine port.
For this reason, a high-pressure PTFE hose should be evaluated as a complete assembly.
Selecting a hose body with sufficient pressure capability does not compensate for an incorrectly matched fitting or improper assembly process.
Oil-based industrial circuits can require:
pressure resistance,
temperature capability,
chemical compatibility.
Potential applications may include:
machinery fluid connections,
lubrication-related systems,
industrial oil transfer,
process equipment.
The PTFE inner tube provides a stable material-contact layer while the double braid supplies mechanical reinforcement.
Water-based process systems may also operate under significant pressure.
Examples include:
industrial test equipment,
process machinery,
pressurized water circuits.
A double-braided flexible connection can be useful where rigid pipe would make machine assembly or maintenance difficult.
The catalog also identifies chemical materials as an application.
PTFE is broadly resistant to many chemicals, making it useful in demanding industrial transfer systems.
Actual compatibility should still be confirmed according to:
chemical type,
concentration,
working temperature,
exposure duration.
This is especially important for critical production processes.
The strongest construction is not automatically the correct one.
A single-braided PTFE hose may be sufficient when:
pressure is moderate,
lower weight is preferred,
greater flexibility is needed.
A double-braided hose becomes more attractive when the application requires greater pressure capability or additional reinforcement.
The selection should therefore be made around the machine’s actual operating conditions.
Jingcheng can customize JCC-01200 hose assemblies according to equipment requirements.
Customization can include:
hose length,
inner diameter,
end fitting type,
thread standard,
different fittings on each end,
connection orientation,
complete OEM hose assemblies.
Customers can also provide an existing hose, drawing or connection photographs for replacement development.
For correct selection, please provide:
transferred medium,
working temperature,
normal working pressure,
maximum expected pressure,
hose length,
required flow,
inner diameter,
minimum bending radius,
fitting type,
equipment application,
expected start-stop operating conditions.
This information helps determine whether a double-braided construction is appropriate.

For equipment manufacturers, the complete hose assembly can be developed around the actual machine rather than relying only on standard catalog configurations.
Pressure rating alone does not fully describe the operating environment of an industrial hose.
Pump starts, valve operation and repeated production cycles can create changing pressure conditions that must be considered during hose selection.
The JCC-01200 double braided PTFE hose combines a smooth PTFE inner tube with two layers of 304 stainless steel reinforcement, making it suitable for demanding gas, oil, water and chemical fluid systems.
For pump-driven machinery and repeated start-stop processes, correct hose selection should consider:
pressure cycle, temperature, diameter, bending radius, fittings and complete system operation.
