Double-Braided PTFE Hose for Industrial Machines Handling Multiple Fluid Types

Modern industrial equipment rarely handles only one kind of fluid.

A single production machine or process skid may contain separate circuits for:

• Oil

• Water-based fluids

• Process gases

• Chemical materials

• Cleaning liquids

• Utility fluids

For machine builders, this creates a practical sourcing challenge.

Using a completely different hose family for every fluid circuit increases the number of specifications, suppliers and spare parts that must be managed.

The JCC-01200-PTFE double-braided hose provides a reinforced PTFE platform that can be considered across a wide range of industrial fluid-handling applications.

Its structure combines:

Smooth PTFE Inner Tube + Two Layers of High-Strength 304 Stainless Steel Braid

This gives the hose a broad operating profile for machinery requiring chemical compatibility, pressure capability and mechanical reinforcement in one flexible assembly.

One Hose Architecture for Different Machine Circuits

For an OEM manufacturer, standardization can be as important as individual hose performance.

Imagine one machine containing:

• A water-based cooling circuit

• An oil circuit

• A chemical dosing line

• A gas supply connection

If suitable operating conditions are confirmed, using the same basic PTFE hose architecture across multiple circuits can simplify engineering and procurement.

This can reduce:

• Supplier complexity

• Spare-part variety

• Technical documentation

• Internal qualification work

• Maintenance confusion

The hose size and fittings may change, but the underlying construction remains familiar to both production and maintenance teams.

Why Double Braiding Provides Additional Structural Support

A PTFE inner tube provides the material-contact path, but PTFE alone is relatively flexible.

Under internal pressure, the tube naturally tries to expand.

The two layers of stainless steel braid provide mechanical restraint around the PTFE tube.

This helps support:

• Pressure stability

• Controlled hose expansion

• Mechanical durability

• More predictable behavior under load

Compared with a single-braided structure, double reinforcement provides an additional layer of support for more demanding industrial systems.

Strong Pressure Capability Across Multiple Sizes

The catalog shows that the working pressure depends on hose diameter.

For example:

• 1/4": approximately 40 MPa

• 5/16": approximately 35 MPa

• 3/8": approximately 32 MPa

• 1/2": approximately 27 MPa

• 5/8": approximately 21 MPa

• 3/4": approximately 20 MPa

• 1": approximately 17 MPa

• 1-1/4": approximately 14 MPa

This wide size range allows the same product family to support different flow requirements inside one machine platform.

The correct size should always be selected according to actual pressure, flow and installation requirements.

Suitable for Gas, Oil, Water-Based and Chemical Media

The catalog specifically identifies the hose for hydraulic transport involving:

• Gas-based fluids

• Oil-based fluids

• Water-based fluids

• Chemical raw materials

This broad application range makes the hose particularly attractive to machinery manufacturers producing multi-function fluid systems.

The PTFE inner surface provides the chemical-contact layer, while the stainless reinforcement supplies mechanical support.

Exact compatibility should still be checked according to:

• Fluid composition

• Concentration

• Temperature

• Pressure

• Exposure time

Wide Temperature Capability

The product is specified for approximately:

-70°C to +260°C

This broad range allows the hose to be considered for equipment operating in very different thermal environments.

Possible examples include:

• Cold-process machinery

• Heated chemical transfer

• Oil circulation

• Process utilities

• Temperature-controlled industrial systems

Working pressure should always be evaluated at the actual operating temperature.

Useful in Machines with Pressure Variation

Industrial pumps and valves rarely create perfectly constant pressure.

A fluid system may experience:

• Pump startup

• Valve switching

• Flow changes

• Temporary pressure peaks

• Machine shutdown and restart

A reinforced hose structure provides greater mechanical support during these changing operating conditions.

This makes the double-braid construction relevant to equipment where long-term stability is more important than simply achieving one maximum pressure value.

Flexible Alternative to Complex Rigid Piping

Rigid pipes can provide excellent pressure performance, but they require precise alignment.

Inside machinery, this can make installation difficult around:

• Pumps

• Valves

• Filters

• Tanks

• Manifolds

• Sensors

A double-braided PTFE hose provides flexible routing while retaining substantial pressure capability.

This can simplify machine assembly and future maintenance.

Typical Applications

Potential applications include:

• Industrial hydraulic machinery

• Chemical processing equipment

• Oil transfer systems

• Gas handling machinery

• Water-based process systems

• Pump connections

• Process skids

• Automated production machinery

• OEM fluid-control equipment

Custom Assembly Options

Jingcheng can customize the complete hose assembly according to:

• Hose length

• Inner diameter

• End fittings

• Thread standard

• Connection orientation

• Equipment installation

• Working pressure

• Customer drawings

An existing hose sample can also be used as a reference for replacement projects.

What Information Should Be Provided?

For correct selection, please provide:

• Fluid type

• Working temperature

• Normal pressure

• Maximum pressure

• Required flow

• Hose length

• Inner diameter

• Minimum bending radius

• Inlet fitting

• Outlet fitting

• Equipment application

Conclusion

The JCC-01200-PTFE double-braided hose is particularly valuable for industrial machinery that must handle different fluid circuits while maintaining a consistent hose platform.

Its smooth PTFE inner tube provides a versatile material-contact surface, while two 304 stainless steel braided layers provide reinforced pressure support.

For OEMs seeking to reduce hose variety while maintaining flexibility across gas, oil, water-based and chemical systems, this structure can provide a practical standardized solution.
