PTFE & FEP & PFA Corrugated Tubing
Product Overview
Flexible fluoropolymer bellows for fluid transfer and equipment connections
Yozonetech supplies PTFE, FEP and PFA corrugated tubing for industrial fluid transfer and flexible connections. Corrugations help accommodate installation offsets, equipment movement and vibration where the tube geometry and assembly are designed for the duty.
The size table covers 14 common specifications, with straight-section dimensions and separate corrugated-section bore and outside-diameter ranges. Select the material and connection dimensions together with the actual medium, temperature, pressure and movement requirements.

Product Benefits
Flexible routing
The corrugated profile allows bends and helps reduce kinking during installation. Agree the minimum bend radius, routing and support for the selected size; flexibility does not establish a fatigue-life rating.
Chemical stability
Fluoropolymer materials offer broad chemical resistance for many cooling fluids and reagents. Check the exact fluid, concentration and temperature against the selected material and complete assembly.
Temperature and aging resistance
The range is intended for applications that require resistance to high and low temperatures, aging and weather exposure. Confirm operating limits for the material grade, tube geometry and mechanical load.
Material and appearance options
FEP and PFA options can provide transparency for fluid inspection. PTFE appearance differs by grade and construction, so confirm translucency or opacity with the selected product.
Adaptable construction
Specify corrugation geometry, straight ends and fitting interfaces to suit assembly and handling. Processing and connection requirements are reviewed against the selected material.

Typical Applications
Chemical and reagent transfer
Flexible connections for corrosive media, solvents and high-purity reagents where the selected material and finished construction meet the application requirements.
Semiconductor and electronic equipment
Connections in process equipment where chemical compatibility, cleanliness and compact routing are required. High-purity supply requirements must be specified and confirmed.
Heat exchange and steam service
Corrugated connections may be reviewed for heat exchange or steam piping duties. Confirm temperature, pressure, support and end connections for the finished assembly.
Movement and vibration accommodation
Use a properly designed flexible connection to accommodate pipe offsets, thermal movement and mechanical vibration. Agree displacement, vibration frequency and required service life.
Food beverage and medical equipment
Equipment fluid paths can be reviewed for these industries. Food-contact compliance, medical suitability and required documentation must be confirmed for the specific material and finished tube.
Custom Production and Inspection
Send a drawing specifying material, straight-end ID and OD, corrugated bore and outside diameter, wall thickness, overall length, active corrugated length, pitch and end configuration. Include dimensional tolerances, quantity, packaging and connection details.
For pressure, vacuum or cyclic movement, provide the full duty conditions and required test criteria. Agree dimensional checks, leak or pressure testing, cleanliness and material documentation before production.
Frequently Asked Questions
Which material should I choose
Specify the fluid, concentration, service temperature and performance requirements. FEP, PFA and PTFE options are reviewed against the actual duty and required construction.
Are the straight and corrugated bore dimensions the same
Do not assume they are the same. Straight-end dimensions define the connection interface; corrugations can change the internal clearance. Confirm the minimum corrugated bore for flow and assembly design.
Can the tubing be used under vacuum
Vacuum suitability depends on size, wall, corrugation geometry, temperature and support. Provide the required vacuum level and duration so the finished tube and assembly can be reviewed.
Can you supply custom lengths and connections
Yes, custom requirements can be reviewed against your drawing. Specify total length, corrugated length, straight ends, fitting type and tolerances. Confirm availability with the quotation.
What are the temperature and pressure ratings
Ratings must be confirmed for the selected material, dimensions, fitting system and service conditions. Request the applicable specification and any required test data for your assembly.
Can the tubing absorb repeated movement
It can be designed for flexible connections, but displacement and cyclic life must be evaluated for the selected tube and installation. Provide movement direction, stroke, cycle rate and required life.
