PTFE Capillary Tubing (ID 0.3–4.8mm)

Product Overview

PTFE Capillary Tubing is a precision small-diameter tubing solution designed for applications requiring accurate fluid control, chemical resistance and reliable performance.

Manufactured from high-quality PTFE material, this tubing provides excellent resistance to acids, solvents, oils and corrosive chemicals. The smooth, non-stick inner surface offers low friction and helps ensure stable fluid flow.

With inside diameters from 0.3mm to 4.8mm, PTFE Capillary Tubing is suitable for laboratory instruments, analytical systems, precision fluid transfer and various industrial applications where compact tubing dimensions are required.

Key Features

• Small ID precision design

Available with inner diameters from 0.3mm to 4.8mm for accurate fluid transfer and control.

• Excellent chemical resistance

Resistant to many aggressive chemicals, solvents, acids and corrosive media.

• Low friction inner surface

Smooth PTFE surface reduces flow resistance and minimizes material adhesion.

• Wide temperature capability

Maintains stable performance in demanding high and low temperature environments.

• Electrical insulation properties

Provides reliable insulation and protection in electrical and electronic applications.

• Flexible supply options

Available with different outside diameters, wall thicknesses and lengths according to application requirements.

Available Specifications

• Material: PTFE (Polytetrafluoroethylene)
• Inside Diameter (ID): 0.3–4.8mm
• Outside Diameter (OD): Multiple options available
