JINGCHENG Spiral Wound Braided PTFE Hose (series JCC-03100-PTFE) lists four sizes from 1/2" to 1" with working pressures from 44 MPa down to 27 MPa for fuel, coolant, lubricant, chemical and hydraulic pipelines from -65°C to +220°C. This page is a spec-sheet reading guide for the JINGCHENG JCC-03100-PTFE spiral-wound braided hose: four catalog sizes, how spiral wire layers raise pressure versus double braid, and the +220°C temperature ceiling you must check before ordering.
On 1/2" to 1" fuel, coolant, lubricant and hydraulic lines, braid-only PTFE hose can run out of pressure margin. The JINGCHENG JCC-03100-PTFE series adds one or two copper-plated steel wire spiral layers under a 304 stainless braid, pushing working pressure to 44 MPa at 1/2" and still 27 MPa at 1", with a -65°C to +220°C window. The table below is the selection document — not a marketing summary.
Smooth PTFE straight inner tube — lightweight, flexible, non-stick, chemically inert bore.
One or two copper-plated steel wire spiral windings — carry radial and hoop stress under continuous pressure and pulsation.
Outer 304 stainless steel braid — locks the spiral layers, takes axial load and protects against abrasion.
Only four catalog sizes: 1/2", 5/8", 3/4" and 1" (12.7–25.0 mm ID). If you need 3/8" or above 1", look at JCC-02100 or JCC-04100 instead.
Pressure steps: 44 / 36 / 33 / 27 MPa working from 1/2" to 1". Burst is about four times working pressure (176.4 MPa at 1/2", 108.1 MPa at 1").
Bend radii are tighter than double braid on the same IDs — for example 90 mm vs 140 mm at 1/2", and 225 mm vs 285 mm at 1" versus JCC-01200 — but still must be respected.
Upper temperature is +220°C, not +260°C. Confirm hot engine-bay or process skin temperatures before ordering.
Hazardous chemical and solvent transfer; fuel, coolant and lubricant pipelines; hydraulic machinery; rail, automotive and marine lines; aviation and aerospace fluid lines where weight and pressure integrity both matter.

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.
vs. JCC-01200 double braid: spiral winding raises 1/2"–1" working pressure from 17–27 MPa to 27–44 MPa and tightens bend radii.
vs. JCC-02100 wire-bundle braid: JCC-02100 covers 3/8"–2" up to +260°C; JCC-03100 concentrates on 1/2"–1" at up to 44 MPa to +220°C.
vs. JCC-04100 aramid braid: choose JCC-03100 for maximum metallic pressure capacity and stainless exterior; choose JCC-04100 for non-metallic lightweight build and anti-static performance.
Match bore and keep continuous/peak pressure inside the row rating.
Leave a straight section behind each end fitting before the first bend.
Align threads or flanges before tightening so spiral layers and braid are not twisted; clamp away from sharp edges and heat sources above +220°C.
Custom diameters, one- or two-layer spiral builds, cut lengths and crimped assemblies are available to your drawings.
