JINGCHENG Smooth Bore PTFE Tube (series JCC-00000-PTFE) is extruded, dried, high-temperature sintered and shaped from PTFE resin, carrying strong acids, alkalis, oxidizers, reducing agents, organic solvents and high-purity chemicals from -70°C to +260°C. This FAQ answers the questions first-time buyers ask about the JCC-00000-PTFE tube — materials and media, the eleven sizes, pressure by size, bend radius, wall thickness, reinforcement, custom sizes, installation and what to send for a quotation.
Buyers who order a smooth bore PTFE tube for the first time usually ask the same questions: how much pressure each size can take, how tightly it can be bent, why the wall gets thicker on larger sizes, and what to send for a quotation. This FAQ answers them with the figures from the JINGCHENG PTFE Hose Catalog for the JCC-00000-PTFE standard smooth bore tube, the first product in our PTFE inner tube series.
It is a special tube made from PTFE (polytetrafluoroethylene) resin, produced by extrusion, drying, high-temperature sintering and shaping. The result is a seamless tube with a smooth, non-stick bore. Standard walls are 1.0 mm to 2.0 mm thick depending on size.
The catalog temperature range is -70°C to +260°C. The tube is suitable for strong acids and alkalis, strong oxidizing agents, reducing agents and various organic solvents, and it is very suitable for transporting high-purity chemicals.
Eleven standard sizes from 5/32" (4.5 mm ID) to 2" (51 mm ID), with ID and OD tolerance of ±0.2 mm. The full catalog table:

Data source: JINGCHENG PTFE Hose Catalog (JCC-00000-PTFE Series). Operating temperature range: -70°C to +260°C. All specifications can be customized according to customer parameters.
Working pressure depends on size. The highest rating in the range is 1.73 MPa (251.33 psi) at 1/4". It then falls with diameter, to 0.93 MPa at 1/2", 0.70 MPa at 1" and 0.40 MPa at 2". Two points buyers often miss:
5/32" is not the strongest size. At 1.40 MPa it is rated below the 1/4" tube (1.73 MPa), because its wall is the same 1.0 mm on a much smaller tube.
3/4" is rated slightly above 5/8". The 3/4" tube has a 1.5 mm wall against 1.2 mm on 5/8", which lifts its working pressure to 0.80 MPa against 0.73 MPa.
Always choose the size so that the maximum system pressure stays below the working pressure. Burst pressure (from 5.6 MPa down to 1.2 MPa) is a safety margin, not an operating limit.
The minimum bend radius grows quickly with diameter: 60 mm at 5/32", 130 mm at 1/4", 270 mm at 1/2", 600 mm at 1" and 1200 mm at 2". A smooth bore tube is best for straight or gently curved routes. If your layout needs tight turns, a convoluted PTFE hose such as our JCC-10000 series is the better choice.
The catalog uses 1.0 mm walls on 5/32" and 1/4", 1.2 mm from 5/16" to 5/8", 1.5 mm on 3/4" and 2.0 mm from 1" to 2". The thicker wall helps the larger tubes keep their shape and pressure rating as the diameter increases.
No. JCC-00000-PTFE is a bare tube. When a line needs higher pressure or mechanical protection, the same type of PTFE tube can be supplied inside a stainless steel braid, for example our single-layer 304 braided JCC-01100 series.
Yes. The catalog states that the tube can be customized according to parameters. Non-standard ID, OD, wall thickness and cut lengths can be discussed.
Cut the tube square with a sharp cutter so the fitting seals evenly.
Use fittings that match the OD and do not overtighten them.
Keep every bend within the minimum bend radius to prevent kinking.
Flush the line between incompatible media; the non-stick bore makes this quick.
