Double-Braided PTFE Hose for Retrofitting Rigid Industrial Fluid Lines

Industrial machines often remain in operation much longer than their original piping design.

During the life of the equipment, users may:

• Replace pumps

• Upgrade valves

• Move process modules

• Change fluid circuits

• Modify production capacity

When this happens, existing rigid pipework may no longer align correctly with the new equipment configuration.

Rebuilding the complete rigid line can be time-consuming.

The JCC-01200-PTFE double-braided hose offers a flexible alternative for suitable retrofit applications.

Its structure combines:

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

The catalog specifies approximately -70°C to +260°C temperature capability.

Equipment Retrofits Often Create Alignment Problems

Original rigid pipework is built around exact component positions.

If a replacement pump is slightly:

• Taller

• Shorter

• Wider

• Oriented differently

the original pipe may no longer fit.

A flexible hose can provide additional tolerance between:

• Pump and manifold

• Valve and tank

• Process module and pipeline

• Hydraulic unit and machine

This can simplify retrofit work.

Double Stainless Steel Braid Provides Strong Mechanical Support

The hose uses two layers of high-strength 304 stainless steel braid around the smooth PTFE inner tube.

The additional reinforcement provides greater structural support compared with simpler single-layer designs.

This makes the hose suitable for demanding fluid systems requiring substantial working pressure.

Strong Pressure Capability Across Several Sizes

Selected catalog values include approximately:

• 1/4": 40 MPa working pressure

• 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

This gives equipment designers a broad range of sizes for different flow and pressure conditions.

Useful for Mixed-Media Industrial Circuits

The catalog identifies hydraulic transfer applications involving:

• Gas-based fluids

• Oil-based fluids

• Water-based fluids

• Chemical raw materials

This broad application range makes the hose relevant to machinery where different circuits require similar reinforced flexible connections.

Actual PTFE compatibility should still be verified for the specific chemical.

A Retrofit Hose Can Reduce the Need for Multiple Adapters

When existing pipework does not line up with a replacement component, installers sometimes add several adapters and elbows.

This can increase:

• Number of sealing points

• Installation complexity

• Overall connection length

A customized flexible hose can often be produced with the required fitting on each end.

This may simplify the final connection.

Useful for Pump and Valve Replacement Projects

Pumps and valves are frequently replaced during machine life.

New models may use different:

• Port positions

• Thread standards

• Dimensions

A custom double-braided PTFE hose can bridge the distance between the existing system and the replacement component.

This makes it useful for maintenance and modernization projects.

Smooth Inner PTFE Tube Provides a Versatile Fluid Path

The material-contact surface is smooth PTFE.

This gives the hose broad compatibility with many industrial media.

The smooth internal path also makes the hose useful where engineers prefer a relatively straightforward flow geometry.

Wide Temperature Capability Supports Equipment Modernization

The catalog specifies approximately:

-70°C to +260°C

This broad temperature range means the same hose family can be considered for multiple process conditions.

This is particularly useful when older equipment is upgraded to operate under different thermal conditions.

Flexible Connections Can Isolate Minor Machine Movement

Rigid pipes directly connect two fixed points.

Flexible hose can accommodate limited:

• Vibration

• Thermal movement

• Alignment differences

This can be useful around:

• Pumps

• Hydraulic units

• Process modules

The hose should still be installed within its specified bending limits.

Suitable for OEM Redesign Projects

The JCC-01200-PTFE is not only useful for maintenance.

OEM manufacturers redesigning an existing machine may use flexible hose to simplify the new layout.

This can make future equipment easier to:

• Assemble

• Service

• Modify

• Upgrade

Custom Hose Assemblies

Jingcheng can customize:

• Inner diameter

• Hose length

• End fittings

• Thread standards

• Different fitting types on each end

• Connection orientation

• Complete assemblies

Existing hose samples, drawings or equipment photographs can be used for preliminary matching.

What Information Should Be Provided?

Please provide:

• Transferred medium

• Working temperature

• Working pressure

• Maximum pressure

• Required flow

• Hose length

• Inner diameter

• Existing connection type

• New equipment connection type

• Minimum bending radius

• Equipment model

Conclusion

Equipment modernization does not always require rebuilding every rigid fluid line.

For suitable applications, a customized flexible hose can provide a simpler connection between existing infrastructure and newly installed components.

The JCC-01200-PTFE combines a smooth PTFE inner tube with two layers of stainless steel reinforcement, giving it the mechanical strength and media versatility needed for many industrial retrofit and hydraulic applications.

For machine upgrades, pump replacements and mixed-media fluid circuits, double-braided PTFE hose provides a practical way to add flexibility without giving up substantial pressure capability.
