JINGCHENG Double Braided PTFE Hose (series JCC-01200-PTFE) covers a smooth PTFE inner hose with two layers of high-strength 304 stainless steel braided wire for the hydraulic transmission of gas-based, oil-based and water-based fluids and chemical materials from -70°C to +260°C. This page shows buyers how to turn the catalog table into a complete request for quotation — hose identification, service conditions, bulk hose versus assemblies, inspection requirements, an example RFQ line and the most common RFQ mistakes.
The JINGCHENG JCC-01200-PTFE hose uses a smooth PTFE hose as the inner layer, covered with two layers of high-strength 304 stainless steel braided wire as the outer reinforcement. It is rated from -70°C to +260°C and the catalog lists it for the hydraulic transmission of gas-based fluids, oil-based fluids, water-based fluids and chemical materials. Because eight standard sizes are offered and every specification can be customized, the quality of the quotation you receive depends largely on the quality of the request you send. A vague enquiry such as "PTFE braided hose, 1/2 inch, 100 m" forces the supplier to guess the pressure, the fittings and the length tolerance, and the first quotation usually has to be revised. This guide shows how to turn the catalog table into a complete request for quotation (RFQ).
Quote the part number and the catalog values in your RFQ so there is no doubt about which build you mean.
Part No. | Nominal Size | Inner Diameter (mm ±0.2) | Tube Outer Diameter (mm ±0.2) | Braided Outer Diameter (mm ±0.2) | Working Pressure (MPa) | Burst Pressure (MPa) | Min. Bend Radius (inch) | Min. Bend Radius (mm) |

Data source: JINGCHENG PTFE Hose Catalog (JCC-01200-PTFE Series). Operating temperature range: -70°C to +260°C. All specifications can be customized according to customer parameters.
Working pressure falls as the bore grows: 40 MPa at 1/4", 32 MPa at 3/8", 27 MPa at 1/2", 20 MPa at 3/4", 17 MPa at 1" and 14 MPa at 1-1/4". Burst pressure, from 120.9 MPa down to 42 MPa, is a safety margin and should never be written into an RFQ as an operating condition.
Part number and nominal size, for example JCC-01213-PTFE, 1/2".
Construction: smooth PTFE inner hose with two 304 stainless steel braid layers. Stating the construction prevents a single braid hose being offered by mistake.
Key dimensions: inner diameter, tube outer diameter and braided outer diameter (for 1/2": 12.6 mm / 15 mm / 18.3 mm, tolerance ±0.2 mm). Fitting suppliers need the braided outer diameter.
Medium: name the fluid (hydraulic oil, compressed gas, water-glycol, a named chemical) and its concentration.
Temperature: the normal and maximum fluid and ambient temperatures, which must stay inside -70°C to +260°C.
Pressure: the normal operating pressure and the maximum peak or surge pressure. Choose the size so the peak stays below the catalog working pressure.
Motion and routing: static or flexing, and the tightest bend in the route. The catalog minimum bend radius ranges from 83 mm at 1/4" and 5/16" to 340 mm at 1-1/4".
RFQ item | Bulk hose | Finished assemblies |
|---|---|---|
Quantity | Total metres and coil length preference | Number of pieces per drawing |
Length | Coil length | Overall length including fittings, with tolerance |
End connections | Not applicable | Thread type and size, sealing face, material |
Marking and tags | Optional | Part number, length, line ID tags |
Packaging | Coils, protected ends | Capped ends, bagged or boxed |
For assemblies, attach a simple drawing showing the overall length, the orientation of angled fittings and any protective sleeves.
State what you expect to receive with the goods: dimensional records against the catalog tolerances, the pressure test you require on assemblies (agreed with the supplier and kept well below burst pressure), and the packing list format. Writing these items into the RFQ avoids disputes after delivery.
JCC-01216-PTFE, 5/8" double 304 braided smooth bore PTFE hose, ID 16.3 mm, braided OD 22 mm; medium: hydraulic oil at 80°C; operating pressure 15 MPa, peak 18 MPa (catalog working pressure 21 MPa); minimum route bend 200 mm (catalog 176 mm); 40 assemblies, overall length 1,500 mm, straight female swivel fittings both ends; capped ends, tagged with part number.
Giving only the nominal size without the part number or braided OD.
Quoting burst pressure as the required rating.
Omitting pressure peaks from pumps and valves.
Leaving out the medium, so material compatibility of fittings cannot be checked.
Forgetting the length tolerance on assemblies.
Part number, size and construction.
Medium, temperature and pressure including peaks.
Routing and minimum bend.
Bulk length or assembly drawing with fittings.
Inspection, marking and packaging requirements.
JINGCHENG supplies the JCC-01200-PTFE series from 1/4" to 1-1/4" as bulk hose or as custom assemblies, and all specifications can be customized according to customer parameters. Send your completed RFQ and our engineers will confirm the size, pressure margin and fittings before quoting.
