Review specifications ↓PRODUCT OVERVIEW
Product overview
FEP tubing is one of the fluoropolymer tubing families listed by AIR PASSAGE. Review the supplied model dimensions and compare the required fluid, temperature and connection conditions with the information for PFA.
Key features
Virgin FEP
Extruded from selected virgin material; no recycled or reprocessed material is added (data sheet).
Transparent for visual monitoring
High-transparency tubing lets you watch media flow in laboratory and chemical-equipment lines.

High-transparency clear, transparent blue and transparent red.
Temperature range
-196°C to +200°C
Working pressure
6 bar (87 psi) – 20 bar (280 psi) at 23°C, depending on the model (data sheet). Burst pressure is not working pressure.

Selection notes and conditions
Selection at a glance
- Product family: FEP Tubing.
- Media / application scope in the supplied data sheet: Strong acids, strong alkalis, salt solutions, organic solvents and oxidizing agents; validate the specific medium and conditions.
- Dimensions: select ID, OD and the stated model values from the table below.
- Inquiry details: include model, dimensions, quantity, fittings and the intended operating conditions.
Define the fluid and exposure conditions
Provide the exact chemical, concentration, temperature and exposure duration. The broad medium description in the data sheet is not a universal chemical compatibility or food-contact approval.
Pressure and temperature conditions
Pressure and temperature ratings are listed separately; send your operating point for a combined-condition check. Working pressure is the design rating; burst pressure is a test value. Confirm the model-specific limits, test conditions and complete fitting assembly before use.
Related selection information
What is FEP tubing?
FEP is the material designation used for this fluoropolymer tubing family. A material name is a starting point for selection, not a complete specification. Compare the exact model, dimensions and available supporting documentation.
Comparing FEP tubing suppliers
A request to an FEP tubing manufacturer should identify ID, OD, length, quantity and the actual medium. Ask for confirmation of chemical compatibility and temperature and pressure conditions for the selected model.
TECHNICAL DATA
Specifications & available sizes
Specifications: TDS-FEP-2026-V6. Model designations and table values below follow the 2026 technical data sheet for this product.
Dimensions and pressure tables are specified at 23°C. Pressure values are in bar (psi) as stated in the data sheet. Working pressure is the design rating and burst pressure is a test value; pressure and temperature ratings are listed separately, so send your operating point for a combined-condition check.
Tolerance, metric/inch size system and, where applicable, layer construction are identified in each row. Physical properties are reference values from the data sheet; test methods and application-specific compliance are reviewed against your requirements.

QUESTIONS
Product FAQ
How is FEP tubing chemical compatibility reviewed?
Provide the exact chemical, concentration, temperature, exposure duration, pressure, cleaning conditions and fitting design. Review those conditions against documentation for the selected FEP tubing model. A material-family name or a general medium listing does not approve every chemical service.
Which source governs the FEP sizes shown here?
The current model table follows TDS-FEP-2026-V6. Only dimensions in this supplied data sheet are listed.
Does the FEP family name confirm fitting compatibility?
No. Confirm the dimensions, tolerance, fitting design and assembly requirements with the selected tubing and connection specification.
What is FEP tubing made of, and what does FEP stand for?
FEP stands for fluorinated ethylene propylene, a melt-processable fluoropolymer. The supplied data sheet lists a melting temperature of approx. 260°C and a finished-product service temperature range of -196°C to +200°C. Send your specific medium and operating conditions for review before ordering.
What are the specifications of FEP tubing?
The 14 listed models cover metric sizes from 2.5 x 4 mm to 12 x 16 mm and inch sizes from 1/8" to 1/2", supplied in 100 m rolls with a tolerance of ±0.10 mm. Working pressure at 23°C runs from 6 to 20 bar (87 to 280 psi) depending on the model, and 24-hour water absorption is approx. 0.01%. Standard colors are high-transparency clear, transparent blue and transparent red. Check the exact model in the specifications table.
Is FEP tubing the same as Teflon or PTFE tubing?
Teflon is a brand name used for several fluoropolymers, including FEP, PFA and PTFE. FEP and PTFE are different materials, so check the material designation and the data sheet rather than the brand name. This page covers the FEP models listed in the specifications table.
