JINGCHENG Wire Bundle Braided PTFE Hose (series JCC-02100-PTFE) builds a smooth PTFE inner hose, a 304 stainless steel braided middle layer and a high-strength 304 wire bundle braided outer layer for good mechanical resistance from -70°C to +260°C. This page maps the six catalog applications — chemical high-pressure spraying, high-pressure gluing, high-pressure conveying, steam, oil and brake hose — to the pressure, bore and bend-radius figures that decide the size, and closes with a selection checklist.
The JINGCHENG JCC-02100-PTFE hose has three layers: a smooth PTFE hose as the inner layer, a 304 stainless steel braided wire middle layer, and an outer layer of high-strength 304 stainless steel wire bundle braided reinforcement, which gives good mechanical resistance. It is rated from -70°C to +260°C. The catalog lists six application areas: chemical high-pressure spraying, high-pressure gluing, high-pressure conveying, steam conveying, oil conveying and brake hose. This page maps each of those applications to the points that matter when choosing a size from the catalog table.

Data source: JINGCHENG PTFE Hose Catalog (JCC-02100-PTFE Series). Operating temperature range: -70°C to +260°C. All specifications can be customized according to customer parameters.
Working pressure stays high across the small and medium sizes, 41 MPa at 3/8", 5/8" and 3/4", 39 MPa at 1/2" and 35 MPa at 1", then falls to 26 MPa at 1-1/4", 17 MPa at 1-1/2" and 18 MPa at 2". Burst pressure is about three times working pressure and is a safety margin, not an operating figure.
Application (catalog) | What drives the selection | Points to check in the table |
|---|---|---|
Chemical high-pressure spraying | Pump pressure and chemical resistance of the PTFE bore | Working pressure of the size; 3/8" to 3/4" offer 39–41 MPa |
High-pressure gluing | Pressure and smooth, non-stick bore for adhesives | Working pressure; bend radius near dispensing heads (75 mm at 3/8") |
High-pressure conveying | Flow rate and pressure together | Inner diameter vs. working pressure; 1" combines 25 mm ID with 35 MPa |
Steam conveying | Temperature and flexibility | Keep within -70°C to +260°C; bend radius by size |
Oil conveying | Pressure and route length | Working pressure; large bores to 50.5 mm ID |
Brake hose | Pressure and compact routing | Small sizes with high ratings and tight radii |
Spraying lines combine high pump pressure with aggressive media. The PTFE inner layer handles the chemistry, and the two 304 layers carry the pressure. For most spraying lines the 3/8" to 3/4" sizes are the natural choice because they keep 39–41 MPa working pressure while staying reasonably flexible.
Adhesive lines benefit from the smooth PTFE bore, which resists sticking and is easier to flush. Near dispensing heads, the route is often tight, so check the minimum bend radius: 75 mm at 3/8" and 113 mm at 1/2".
Where flow rate matters, compare inner diameter with working pressure. The 1" size (25 mm ID) still offers 35 MPa, while 1-1/4" (31.5 mm ID) offers 26 MPa.
For steam and oil lines, keep the operating temperature within -70°C to +260°C and plan the route around the bend radius, which grows to 490 mm at 1-1/4", 650 mm at 1-1/2" and 900 mm at 2". Large bores are best for straight or gently curved runs.
Brake applications use compact routes and high pressure, which favours the smaller sizes in the table with their high working pressure and shorter bend radii.
Confirm the maximum system pressure, including spikes, is below the working pressure of the size.
Confirm the temperature is within -70°C to +260°C.
Check that the route respects the minimum bend radius.
Match fittings to the inner diameter and the braided outer diameter (for example 12.7 mm ID / 18.3 mm braided OD at 1/2").
Specify length and end connections.
Eight standard sizes from 3/8" to 2" are available, and all specifications can be customized to customer parameters. Send us your application, medium, pressure, temperature, size, length and fittings, and our engineers will recommend the right JCC-02100-PTFE build.
