Description
This high-performance 25% glass filled PTFE tube is engineered for demanding industrial and engineering applications where exceptional chemical resistance, dimensional stability, and low friction are essential. Reinforced with 25% glass fibre, it offers increased rigidity and wear resistance compared with standard PTFE, while retaining excellent non-stick and thermal properties.
Designed for use in harsh environments, this tube withstands continuous service temperatures from -200°C up to 300°C, making it suitable for both cryogenic and high-temperature duties. Available in a choice of outside diameters, wall thicknesses and lengths, it is ideal for precision components, fluid transfer, insulation, and sealing applications across engineering, chemical processing, and laboratory settings.
Product Features
- Manufactured from PTFE filled with 25% glass fibre for enhanced mechanical strength and wear resistance.
- Wide size range with outside diameters of 25 mm, 30 mm, 35 mm, 40 mm, 45 mm and 50 mm to suit varied design requirements.
- Multiple wall thickness options of 5 mm, 7.5 mm, 10 mm and 12.5 mm for optimised balance of rigidity, flow capacity and weight.
- Supplied in standard lengths of 1000 mm or 2000 mm, allowing flexibility for both small projects and larger production runs.
- Outstanding temperature resistance from -200°C to +300°C for both low-temperature and high-temperature service.
- Excellent chemical resistance to a wide range of acids, alkalis and solvents, typical of PTFE materials.
- Low friction, low stick surface for smooth media flow and reduced build-up of residues.
Key Features and Benefits
- Enhanced dimensional stability from glass filling reduces deformation under load, improving component accuracy and service life.
- Extended wear performance compared with unfilled PTFE helps reduce maintenance intervals and downtime.
- Broad operating temperature range enables a single material solution for both cryogenic lines and high-temperature process equipment.
- Multiple diameter and wall thickness combinations make it easy to match tube selection to pressure, flow and space constraints.
- Outstanding chemical inertness supports use with aggressive media, helping minimise risk of corrosion and contamination.
- Excellent electrical insulation properties allow use in high-performance electrical and electronic insulation applications.

Frequently Asked Questions
What are the main advantages of 25% glass filled PTFE compared with standard PTFE tube?
The addition of 25% glass fibre significantly improves the mechanical strength, stiffness and wear resistance of the PTFE tube, reducing creep and deformation under load. This makes it more suitable for structural or load-bearing components while still providing the low friction, chemical resistance and wide temperature range associated with standard PTFE.
Can this glass filled PTFE tube be machined to custom components?
Yes, the tube can be machined using appropriate tooling and techniques suitable for filled PTFE materials. It can be turned, drilled and milled to produce precision parts such as bushes, spacers, seals and insulating components. Care should be taken to support the material properly and to use sharp tools to achieve the best finish.
Is the tube suitable for contact with aggressive chemicals at high temperatures?
The tube offers excellent chemical resistance typical of PTFE and can generally be used with many aggressive chemicals across its full temperature range. However, performance can depend on the specific chemical, concentration and operating conditions, so it is advisable to check compatibility data for the media in question and, where necessary, carry out practical testing.
