Industrial equipment is becoming increasingly compact.
Pumps, valves, filters, vessels, dosing modules and processing components are often installed within the same skid or machine frame. As available installation space decreases, connecting these components with conventional rigid piping or large-bend-radius hoses becomes increasingly difficult.
The challenge becomes even greater when the equipment must later be opened for inspection, cleaning, component replacement or production changeover.
A hose may therefore need to perform two functions at the same time:
carry the process fluid reliably and provide enough flexibility for equipment installation and servicing.
The JCC-11100-PTFE convoluted braided hose is designed for applications where flexibility, compact routing and mechanical reinforcement are required together.
Its construction combines a highly flexible convoluted PTFE hose with a high-strength 304 stainless steel braided reinforcement layer.
According to the product catalog, the hose provides:
Operating temperature from approximately -70°C to +200°C
Very small minimum bending radius
Multiple sizes from 1/4" to 2"
Stainless steel braided reinforcement
Applications in food, pharmaceutical and chemical industries
This makes it particularly suitable for equipment where a conventional smooth PTFE hose would require too much installation space.
In a large chemical plant, pipework can often be routed around equipment with generous space.
Compact processing machinery is different.
A hose may need to pass between:
Pump bodies
Valve manifolds
Filters
Instrumentation
Support frames
Electrical enclosures
Mixing or dosing modules
At the same time, engineers need to avoid sharp bending and unnecessary fitting stress.
If a hose has a large minimum bending radius, the equipment designer may need to increase the entire machine footprint simply to accommodate the hose.
This is one reason highly flexible convoluted PTFE hose can be valuable.
One of the most important characteristics of JCC-11100 is its bending capability.
The catalog lists very small minimum bending radii for the smaller sizes.
Examples include approximately:
1/4" — 10 mm
5/16" — 15 mm
3/8" — 20 mm
1/2" — 25 mm
5/8" — 30 mm
Even the larger sizes maintain substantial flexibility compared with many rigid or smooth-bore alternatives.
This allows equipment designers to create shorter and more compact fluid paths.
Instead of routing a hose through a large loop, the connection can often remain much closer to the equipment.
One especially useful application is the creation of a service loop.
A service loop is a short flexible section that allows a component to be moved slightly during:
Inspection
Cleaning
Filter replacement
Pump maintenance
Valve servicing
Component removal
Without a flexible service connection, maintenance personnel may need to disconnect several rigid pipes before accessing a component.
A highly flexible hose can provide limited movement while keeping the system layout compact.
This can simplify maintenance-oriented machine design.
Machine components are not always positioned with perfect alignment.
Differences can occur because of:
Manufacturing tolerances
Assembly variation
Replacement components
Machine redesign
Field installation
With rigid piping, even a small positional difference can require:
Additional elbows
Adapters
Pipe modification
Reworking of support brackets
A convoluted hose can accommodate limited positional differences between connection points.
This does not mean that the hose should be used to correct major installation errors, but it can provide useful tolerance inside real machinery.
Flexibility alone is not enough.
The JCC-11100 hose also uses a high-strength 304 stainless steel braided outer layer.
The braid provides mechanical reinforcement around the convoluted PTFE structure.
This helps support the hose under internal pressure while preserving the flexibility created by the convoluted geometry.
The resulting structure combines:
PTFE chemical resistance + corrugated flexibility + stainless steel reinforcement
which makes it useful in demanding process equipment.
The catalog provides working-pressure ratings for sizes from 1/4" to 2".
Selected values include approximately:
1/4" — 2,001 psi / 13.8 MPa
5/16" — 1,957.5 psi / 13.5 MPa
3/8" — 1,631.3 psi / 11.3 MPa
1/2" — 1,540.6 psi / 10.6 MPa
5/8" — 1,395.6 psi / 9.6 MPa
3/4" — 1,141.9 psi / 7.9 MPa
1" — 725 psi / 5 MPa
2" — 453.1 psi / 3.1 MPa
This demonstrates an important design principle:
As hose diameter increases, working pressure generally decreases.
The hose should therefore be selected according to both:
required flow diameter and actual operating pressure.
The JCC-11100 family covers nominal sizes from approximately:
1/4" to 2"
This allows the same hose concept to be used across different fluid circuits.
Smaller sizes may be suitable for:
Dosing
Sampling
Instrument connections
Small process modules
Larger sizes may be used for:
Product transfer
Vessel connections
Pump lines
Larger processing equipment
This can help OEM manufacturers standardize around one hose family while selecting different diameters for different machine functions.
The catalog identifies the pharmaceutical industry as one of the applications for JCC-11100.
Potential equipment positions can include flexible connections between:
Process vessels
Pumps
Filters
Transfer modules
Filling equipment
The high flexibility is particularly useful when machine components need to be removed or serviced.
For regulated applications, the exact material documentation and finished hose configuration should be confirmed according to project requirements.
Food-processing machinery often combines multiple components inside a relatively small machine footprint.
Possible equipment includes:
Ingredient dosing systems
Mixing equipment
Filling machines
Transfer skids
Pump modules
Where rigid piping would make cleaning or service access difficult, a flexible convoluted PTFE hose can provide a more adaptable connection.
The catalog also references US FDA 21 CFR 177.1550 among its product documentation references.
The documentation applicable to the exact ordered hose configuration should be confirmed for each project.
Chemical-processing machinery often needs both chemical resistance and flexible routing.
Potential applications include:
Chemical dosing equipment
Solvent transfer
Pump connections
Laboratory chemical systems
Process skids
Corrosive fluid transfer
PTFE provides broad resistance to many chemicals, including many acids, alkalis and solvents.
However, actual chemical compatibility should always be confirmed using the specific medium, concentration and temperature.
A smooth tube resists bending because the inner wall must compress while the outer wall stretches.
The convoluted structure changes this behavior.
Individual convolutions can move relative to one another as the hose bends.
This allows the hose to achieve a much tighter radius without requiring the entire tube wall to deform in the same way as a smooth hose.
This is the main mechanical advantage of the JCC-11100 structure.
A convoluted braided PTFE hose is particularly useful when:
Installation space is limited
Connection points are close together
Components require maintenance access
A service loop is needed
Equipment experiences limited movement
Very small bending radius is important
A smooth-bore hose may still be preferable when maximum flow smoothness or minimum internal geometric complexity is the primary requirement.
The correct structure depends on the equipment.
One of the interesting features of the JCC-11100 range is that it extends up to approximately 2 inches.
Large flexible PTFE connections can be useful where:
Rigid pipe alignment is difficult
Equipment modules need to be disconnected
Larger product transfer lines require flexibility
The catalog shows a minimum bending radius of approximately:
1-1/4" — 100 mm
1-1/2" — 155 mm
2" — 200 mm
For these diameters, the ability to maintain flexibility can simplify installation compared with many rigid alternatives.
The product catalog specifies an operating temperature range of approximately:
-70°C to +200°C
This supports applications involving both low-temperature and elevated-temperature process conditions.
Examples may include:
Chemical fluids
Heated process materials
Cleaning fluids
Temperature-controlled transfer systems
Pressure capability should be evaluated at the real operating temperature rather than assuming the room-temperature rating applies unchanged at every temperature.
Although the hose is highly flexible, correct installation still matters.
Engineers should avoid:
Twisting the hose during installation
Bending directly at the fitting
Excessive unsupported hose weight
Abrasion against sharp machine edges
Continuous operation below the specified bending radius
A flexible hose should be allowed to bend naturally.
The fittings should not be used as the primary flexing point.
A very flexible hose can tempt designers to specify excessive hose length.
But longer is not always better.
Excess hose can increase:
Fluid volume
Pressure drop
Weight
Installation clutter
Potential movement
The ideal hose should be long enough to provide the necessary movement and service access without creating unnecessary loops.
Different machines use different connection standards.
Jingcheng can customize hose assemblies with fittings according to customer drawings or existing equipment.
Customization can include:
Hose length
Inner diameter
End fitting type
Thread standard
Different fittings on each end
Fitting angle
Connection orientation
Complete OEM hose assembly
For replacement projects, customers can also provide photographs or an original hose for preliminary matching.
For JCC-11100 hose selection, the most useful information includes:
Transferred medium
Working temperature
Working pressure
Maximum pressure
Required flow rate
Hose length
Inner diameter
Available installation space
Required bending radius
End fittings
Whether the hose experiences movement
Equipment type
These parameters help determine whether the convoluted braided structure is appropriate for the application.

The main value of a PTFE convoluted braided hose is not simply flexibility.
Its real advantage is the ability to create reliable fluid connections in places where conventional hose routing becomes difficult.
The JCC-11100 combines a highly flexible convoluted PTFE structure with 304 stainless steel braided reinforcement, offering very small bending radii, multiple diameter options and an operating temperature range of approximately -70°C to +200°C.
For pharmaceutical, food and chemical equipment, it can be especially useful for compact process skids, maintenance service loops, closely spaced machine components and flexible equipment connections.
By choosing the correct diameter, pressure rating, hose length and fitting configuration, OEM manufacturers can create more compact and serviceable fluid systems without relying on multiple rigid elbows and adapters.
