JINGCHENG Inner Spiral Convoluted PTFE Hose (series JCC-10000-PTFE) has corrugated inner and outer walls for extremely strong bending performance from -70°C to +260°C and is used in the pharmaceutical, food and chemical industries. This page compares the JCC-10000-PTFE convoluted hose with the JCC-00000-PTFE smooth bore tube on bend radius, pressure, flow path, cleaning and outer diameter, and closes with a simple rule for choosing between them.
When a fluid line has to be made of PTFE, the first choice is usually between a smooth bore tube and a convoluted hose. Both are made from PTFE and both cover -70°C to +260°C, but they behave very differently in a layout. This page compares the JINGCHENG JCC-10000-PTFE inner spiral convoluted hose with our JCC-00000-PTFE smooth bore tube, using the catalog figures, so you can decide which one fits your line.
According to the JINGCHENG PTFE Hose Catalog, the JCC-10000-PTFE hose is a PTFE hose whose inner and outer walls are both corrugated, giving it extremely strong bending performance. The temperature range is -70°C to +260°C, and the catalog lists it as suitable for the pharmaceutical industry, food industry and chemical industry. Ten standard sizes run from 1/4" (6.5 mm ID) to 2" (50 mm ID), ID and OD tolerance ±0.3 mm.

Data source: JINGCHENG PTFE Hose Catalog (JCC-10000-PTFE Series). Operating temperature range: -70°C to +260°C. All specifications can be customized according to customer parameters.
This is where the convoluted hose stands out. Compare the same nominal sizes:
Nominal size | Convoluted JCC-10000 min. bend radius | Smooth bore JCC-00000 min. bend radius |
|---|---|---|
1/4" | 20 mm | 130 mm |
1/2" | 26 mm | 270 mm |
1" | 80 mm | 600 mm |
2" | 125 mm | 1200 mm |
At 1/2" the convoluted hose bends about ten times tighter than the smooth tube. For compact skids, pump connections, moving parts and routes with several turns, that difference decides the design.
The convolutions that give flexibility also limit pressure. The JCC-10000 hose is a low-pressure line: 0.4 MPa (60 psi) working pressure from 1/4" to 1/2", 0.3 MPa from 5/8" to 1-1/2", and 0.2 MPa at 2". Burst pressure ranges from 1.4 MPa to 0.8 MPa. The smooth bore tube carries more pressure at the same size, for example 0.93 MPa against 0.4 MPa at 1/2". If your line needs higher pressure and tight bends at the same time, look at the braided convoluted version (JCC-11100 series).
A smooth bore gives the cleanest flow path and the lowest resistance, and it drains completely. A convoluted bore has ridges, so allow for slightly higher flow resistance and flush the line thoroughly between products. In practice many plants use smooth tube for fixed straight runs and the convoluted hose for the flexible sections that connect to pumps, valves and moving equipment.
The convoluted hose has a larger outer diameter than the smooth tube at the same ID, because the corrugation adds height. For example, the 1" JCC-10000 hose has a 25 mm ID and 35 mm OD. Check the OD when you select clamps, sleeves and wall pass-throughs.
Choose the inner spiral convoluted hose (JCC-10000) when:
The route has tight turns or limited space
The line connects to vibrating or moving equipment
Working pressure stays at or below 0.2–0.4 MPa depending on size
Choose the smooth bore tube (JCC-00000) when:
The route is straight or gently curved
You need the highest pressure an unreinforced PTFE tube can offer
Complete drainage and minimum flow resistance matter most
Respect the minimum bend radius, even though it is small; do not crush the convolutions.
Avoid twisting the hose about its axis during connection.
Support long horizontal runs so the hose does not sag between fittings.
Flush after each product change, paying attention to the ridged bore.
The catalog states that the hose can be customized according to parameters. Send us the medium, temperature, pressure, size and length, and JINGCHENG will confirm whether the convoluted hose or the smooth bore tube is the right fit and send a quotation.
