Double Braided Smooth Bore PTFE Hose Selection Guide for Hydraulic Oil, Gas and Water-Based Fluids

JINGCHENG Double Braided Smooth Bore PTFE Hose (series JCC-01200-PTFE) reinforces a smooth PTFE tube with two layers of 304 stainless steel braid, giving working pressures from 40 MPa at 1/4" down to 14 MPa at 1-1/4" for gas-, oil- and water-based hydraulic fluids and chemicals from -70°C to +260°C. This page walks through the JINGCHENG JCC-01200-PTFE double-braid catalog row by row: how to pick a size for hydraulic oil, gas or water-glycol duty, what the second braid adds versus single braid, and the bend-radius limits that cause most installation failures.

Selecting Double Braid When Single Braid Runs Out of Margin

Hydraulic and fluid-power circuits that see continuous pressure, pulsation and mixed media (gas, mineral oil, water-glycol or chemicals) often outgrow a single 304 braid. The JINGCHENG JCC-01200-PTFE double-braid hose adds a second high-strength 304 stainless steel braid over a smooth PTFE tube, lifting mid- and large-size ratings — for example 27 MPa at 1/2" and 17 MPa at 1" — while keeping the same -70°C to +260°C window.

How to Read the JCC-01200 Spec Rows

1. Start at 1/4". The highest working pressure in the series is 40 MPa (burst 120.9 MPa) on JCC-01206-PTFE.

2. Watch the step-down. 5/16" is 35 MPa, 3/8" is 32 MPa, 1/2" is 27 MPa, then 21 / 20 / 17 / 14 MPa through 5/8", 3/4", 1" and 1-1/4". Always use the row for your ID.

3. Bend radius is not optional. Minimum bend radius runs from 83 mm at 1/4" to 340 mm at 1-1/4". Sharp bends at the fitting are a frequent installation failure.

4. One PTFE bore, many fluids. The catalog positions this series for gas-based, oil-based and water-based hydraulic fluids and chemical materials — useful when several circuits share one hose type.

Construction Checklist

• Smooth, low-friction PTFE inner tube that does not swell in hydraulic oils, gases, water-based fluids or most chemicals.

• Two layers of 304 stainless steel braid for hoop and axial load plus abrasion protection.

• Corrosion-resistant exterior suitable for humid plant and outdoor service.

Typical Installations

• Pressure and return lines on presses, injection molding machines, machine tools and mobile hydraulics.

• High-pressure gas lines on test benches and industrial equipment.

• Water-glycol and other water-based hydraulic circuits.

• Pressurized chemical transfer where rubber-lined hose would be attacked.

Size and Pressure Table (JCC-01200-PTFE Series)

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.

Comparison Notes

• vs. JCC-01100 single braid: lighter and tighter-bending; the second braid on JCC-01200 raises pressure in mid/large sizes (27 vs 23 MPa at 1/2", 17 vs 10 MPa at 1") and adds 1-1/4".

• vs. JCC-02100 wire-bundle braid: JCC-02100 extends to 2" for heavy spray/steam/oil duty; JCC-01200 is the compact double-braid choice from 1/4" to 1-1/4".

• vs. rubber hydraulic hose: PTFE stays compatible across gas-, oil- and water-based fluids up to +260°C, so one construction can serve several circuits.

Installation and Order Checklist

1. Keep continuous and peak pressure inside the rated working pressure for the selected size.

2. Route at or above minimum bend radius; avoid sharp bends at fittings.

3. Confirm fluid and ambient temperatures within -70°C to +260°C; share media lists for critical services.

4. Align ends before tightening, avoid twisting the braid, leave slack for length change under pressure.

5. JINGCHENG supplies bulk double-braid hose and custom assemblies with JIC, NPT, BSP, metric or flange ends to your drawings.
