JINGCHENG Anti-Static PTFE Hose Series is offered in four constructions — anti-static smooth bore, anti-static convoluted, anti-static smooth-ID/convoluted-OD and all-black conductive convoluted — so flammable-liquid, chemical-treatment, electrostatic-coating and food industry lines can match wall design to routing and static-control needs from -60°C to 260°C. This page is a construction-by-construction reading guide for the JINGCHENG anti-static PTFE hose series: how smooth bore, convoluted, smooth-ID/convoluted-OD and all-black conductive walls differ, which failure modes each one prevents, and how to match a wall design to flammable-liquid, coating and food industry lines.
Standard PTFE is chemically inert and works from -60°C to 260°C, but it is also an excellent electrical insulator. When fuels, solvents or coating materials move quickly through an insulating tube, charge collects on the wall; a discharge near flammable vapor or coating mist is an ignition risk, and in electrostatic (static load) coating systems the same charge attracts dust and disturbs film quality. The JINGCHENG anti-static PTFE hose series keeps PTFE's chemical resistance, water repellency and low friction, and adds static control. It is not a single part-numbered braid family: the catalog offers four constructions so you match wall geometry to routing and the level of conductivity your safety concept requires.
Use the wall-structure column first, then the main benefit, then the typical use. Do not treat "anti-static PTFE hose" as one interchangeable item.
Anti-static smooth bore hose — smooth inside and outside. Lowest flow resistance and the easiest bore to flush; the default for straight chemical-liquid-treatment and flammable-liquid runs.
Anti-static convoluted hose — a corrugated wall that increases flexibility for tight routing on coating and dosing equipment.
Anti-static smooth-ID/convoluted-OD hose — a smooth inner bore for flow and cleaning with a convoluted outer wall for flexibility, when a line needs both.
All-black conductive convoluted hose — conductivity throughout the hose, for systems that specify a fully conductive convoluted construction rather than an anti-static tube.
If the inquiry only says "anti-static PTFE" without a wall type, ask whether the run is straight or tightly routed, and whether the specification is anti-static or fully conductive. That choice decides among the four rows.
Charge accumulation on insulating PTFE: fast, low-conductivity liquids and gases build static on a standard tube wall.
Ignition at a discharge: a spark near solvent vapor, fuel or coating mist can start a fire or explosion.
Coating defects: static attracts dust and disturbs film quality on static load coating lines.
Material limits of anti-static rubber: many anti-static rubber hoses swell or degrade in fuels and strong chemicals and have a narrower temperature window than -60°C to 260°C.
Anti-static PTFE addresses those points without giving up PTFE's inertness. It does not remove the need to ground the assembly: the hose is one part of a continuous dissipation path through fittings and bonded equipment.

Anti-static smooth-ID/convoluted-OD hose | Smooth bore, convoluted outer wall | Clean flow path plus flexibility | Coating, food and chemical lines needing both |
All-black conductive convoluted hose | Fully black conductive convoluted wall | Conductivity through the entire hose | Electrostatic coating, flammable liquid transfer |
Property | Catalog Value |
|---|---|
Temperature range | -60°C to 260°C |

Chemical behavior | Corrosion resistant, water-repellent, highly inert |
Data source: JINGCHENG PTFE Hose Catalog (PTFE Anti-Static Series). Diameters, wall thickness and lengths are produced according to customer requirements.
Read the characteristics table as selection limits, not as decoration:
Temperature: stay inside -60°C to 260°C. The catalog notes that the hose handles high temperature and high pressure without hardening at low temperature.
Dielectric strength: the anti-static PTFE tube can withstand 50 V to 120 kV.
Friction: about 0.1, with static and dynamic coefficients almost the same, which keeps flow resistance and product build-up low.
Wear: the smooth, slippery surface provides natural lubrication and a very low static friction coefficient under a 500 psi load.
Weight and mechanics: very lightweight, with shock absorption and high impact resistance.
Static control: the defining property — it helps prevent charge accumulation.
Chemistry: resists various types of corrosion, is water-repellent and is highly inert to chemicals.
The catalog does not publish a single working-pressure column for this series. Diameters, wall thickness and lengths are produced to the customer's parameters; for higher pressure, a braided anti-static construction can be recommended once inner diameter, flow and pressure are known.

The JINGCHENG PTFE hose catalog lists four typical fields: chemical liquid treatment (transfer, dosing and sampling of acids, alkalis and solvents); transportation of flammable liquids (fuel and solvent lines); static load coating industry (paint and coating supply on electrostatic spraying systems); and the food industry, where process lines need PTFE's inert, non-stick surface together with static control.
Name the medium, its flammability and its temperature; PTFE is inert to a very wide range of chemicals, but the process must stay within -60°C to 260°C.
State whether the safety concept requires anti-static hose or a fully conductive hose — that is the split between the three anti-static walls and the all-black conductive convoluted hose.
Match flexibility to the route: smooth bore for straight runs and easy flushing; convoluted versions for tight bends or moving connections; smooth-ID/convoluted-OD when you need a clean bore and extra flexibility together.
Send inner diameter, flow and pressure. This series is sized to order; higher pressure may need braid.
Specify fittings and the grounding method so the finished assembly dissipates charge continuously.
JINGCHENG manufactures the four constructions to customer parameters — inner and outer diameters, wall structure, cut lengths, end fittings, braiding and protective sleeves — for chemical equipment builders, coating system integrators, food machinery manufacturers and distributors. Share drawings or operating conditions for a construction recommendation and quotation.
