High-Precision PTFE Tubing
Custom PTFE Tubing for Demanding Industrial Applications
PTFE (polytetrafluoroethylene) tubing is a high-performance specialty tubing known for its excellent chemical and temperature resistance, low friction, non-stick surface and electrical insulation. These properties make it suitable for demanding fluid handling, insulation, protection and precision component applications.
We specialize in high-precision and custom PTFE tubing, supporting different inner and outer diameters, wall thicknesses, tolerances, colors and configurations. With precision extrusion, in-line dimensional inspection and controlled production, we turn customer drawings, samples and specifications into consistent PTFE tubing solutions for a wide range of industrial applications.
| Material | OD(mm) | ID(mm) | Min.Thickness | Tolerance of Thickness(mm) | Tolerance of ID and OD(mm) |
| PTFE | 1.8-12 | 1.5-11 | ≥0.12 | ≤0.10 | ≥±0.05 |
What Is High-Precision PTFE Tubing?
PTFE (polytetrafluoroethylene), commonly known as Teflon and sometimes referred to as the “Plastic King,” is a fluoropolymer used to produce tubing, seals, linings and other engineered components. PTFE tubing is formed from PTFE resin through controlled manufacturing processes to achieve the required tube structure and dimensions.
The term high-precision PTFE tubing refers to tubing manufactured with tighter control over key dimensions such as inner diameter (ID), outer diameter (OD) and wall thickness. This dimensional consistency is particularly important when the tubing must fit precisely with connectors, maintain a defined flow path or meet the dimensional requirements of an integrated component.
Unlike general-purpose PTFE tubing, high-precision tubing is produced according to defined dimensional specifications and inspection requirements. The appropriate tolerance depends on the tube size, structure, application and production method.
