JINGCHENG Spiral Wound Braided PTFE Hose (series JCC-03100-PTFE) reinforces a lightweight, flexible PTFE straight inner pipe with one or two layers of copper-plated steel wire winding and a 304 stainless steel braided outer layer for fuel, gas, strong acid, strong alkali and organic solvent lines from -65°C to +220°C. This page sets out a seven-step incoming inspection routine — documents, visual checks, dimensions against the ±0.2 mm catalog tolerance, bend check, proof test on assemblies, cleanliness and release records — with a visual acceptance table and a checklist.
The JINGCHENG JCC-03100-PTFE hose has an inner PTFE straight pipe that is lightweight with flexible bending performance, one or two layers of copper-plated steel wire winding as the middle reinforcement, and a 304 stainless steel braided steel wire outer layer. It resists -65°C to +220°C and conveys fuel, gas, strong acids, strong alkalis and various organic solvents. The catalog lists it for the transmission of hazardous chemicals, for fuel, coolant and lubricant delivery pipelines, and for hydraulic machinery, trains, automobiles, ships, airplanes, rockets, spacecraft and satellites. Lines like these are expensive to shut down, so many buyers inspect each delivery before the hose goes into stock or into an assembly. This guide sets out a practical incoming inspection and test routine based on the catalog data.
Use the catalog table as the acceptance reference. Diameters carry a tolerance of ±0.2 mm.
Part No. | Nominal Size | Inner Diameter (mm ±0.2) | Tube Outer Diameter (mm ±0.2) | Braided Outer Diameter (mm ±0.2) | Working Pressure (psi) | Working Pressure (MPa) | Burst Pressure (psi) | Burst Pressure (MPa) | Min. Bend Radius (inch) | Min. Bend Radius (mm) |
|---|---|---|---|---|---|---|---|---|---|---|
JCC-03113-PTFE | 1/2" | 12.7 | 15.1 | 19.3 | 6394.5 | 44 | 25578 | 176.4 | 3.54 | 90 |
JCC-03116-PTFE | 5/8" | 15.8 | 18.8 | 22.8 | 5165.6 | 36 | 20663 | 142.5 | 4.72 | 120 |
JCC-03119-PTFE | 3/4" | 18.8 | 21.8 | 26.2 | 4756 | 33 | 19024 | 131.2 | 5.91 | 150 |
JCC-03125-PTFE | 1" | 25.0 | 29 | 33.0 | 3918.6 | 27 | 15675 | 108.1 | 8.86 | 225 |
Data source: JINGCHENG PTFE Hose Catalog (JCC-03100-PTFE Series). Operating temperature range: -65°C to +220°C. All specifications can be customized according to customer parameters.
Working pressure is 44 MPa at 1/2", 36 MPa at 5/8", 33 MPa at 3/4" and 27 MPa at 1". Burst pressure (176.4 MPa to 108.1 MPa) is a design margin; it is not a test level for hose that will go into service.
Compare the part number, size and quantity on the packing list with the purchase order.
Confirm the coil or assembly tags match the part number, for example JCC-03119-PTFE, 3/4".
Keep the delivery records so each lot can be traced to its installation.
Item | What to look for | Reject or query if |
|---|---|---|
Outer 304 braid | Even, tight weave along the length | Broken or protruding wires, loose or bird-caged braid |
Hose body | Straight, round section | Kinks, flattening or crushed areas |
Cut ends | Square cut, tidy wire ends | Frayed winding or braid at the end |
PTFE bore | Clean, smooth inner wall | Debris, scratches or deformation at the ends |
Fittings (assemblies) | Even crimp, correct thread | Cracked ferrules, damaged threads or sealing faces |
End protection | Caps or plugs fitted | Open ends exposed to dirt |
Measure a sample from each lot with a calibrated caliper. Check the inner diameter, the PTFE tube outer diameter and the braided outer diameter against the table, for example 12.7 / 15.1 / 19.3 mm at 1/2" and 25.0 / 29 / 33.0 mm at 1". A braided OD outside tolerance is important because it affects the grip of crimped fittings.
Bend a sample gently to the catalog minimum bend radius, 90 mm at 1/2", 120 mm at 5/8", 150 mm at 3/4" and 225 mm at 1", and confirm the hose bends smoothly without kinking or braid distortion. Never bend tighter than the catalog radius during inspection.
For finished assemblies, carry out a hydrostatic proof test at the level agreed in your purchase order. Keep the test pressure well below the catalog burst pressure, hold it for the agreed time, and look for leaks at the fittings, sweating through the braid or movement of the hose in the ferrule. Use a liquid test medium compatible with your service, and dry and cap the assembly afterwards. Parts that have been taken to burst must never be returned to stock.
For fuel, coolant and solvent service, inspect the bore at both ends with a light and confirm the end caps were in place on arrival. Flush assemblies if your system requires it before installation.
Record the lot, dimensions measured, test results and inspector, then release accepted hose to stores with end caps fitted. Quarantine any queried items and send photos and measurements to the supplier.
Documents and tags match the order.
Braid, body, ends and bore pass visual inspection.
Diameters within ±0.2 mm of the catalog table.
Sample bends to the catalog radius without kinking.
Assemblies pass the agreed proof test with no leaks.
Results recorded and ends capped.
Four standard sizes from 1/2" to 1" are available, and all specifications can be customized according to customer parameters. Tell us your medium, pressure, temperature, sizes, lengths, fittings and inspection requirements, and our engineers will confirm the JCC-03100-PTFE build and the records supplied with each delivery.
