What Is Viton Tubing?
Viton tubing is a flexible tube made from a fluoroelastomer commonly identified as FKM or FPM. It is selected for fluid-handling applications where ordinary rubber tubing may lose strength, swell or allow excessive permeation when exposed to fuels, oils, solvents or elevated temperatures.
Our custom Viton tubing can be produced for fuel lines, chemical transfer, vacuum service, industrial equipment and other demanding fluid paths. The final design is developed around the required inner diameter, outer diameter, wall thickness, cut length, pressure, bending radius and media compatibility.
Viton™ and FKM: What Is the Difference?
“Viton™” is a trademarked fluoroelastomer brand, while FKM and FPM are international material designations. In practice, the actual performance depends on the selected compound grade, fluorine content, curing system, hardness and operating conditions.
For this reason, tubing should not be selected by the name “Viton” alone. The fluid, temperature, pressure, vacuum level and movement should be reviewed before confirming the compound and dimensions.

Why You Choose Fkm Tubing for Demanding Fluid Paths?
Viton tubing is selected when a fluid path must withstand fuel, oil, selected chemicals, temperature variation and permeation concerns. Compared with general-purpose rubber tubing, the appropriate FKM grade can provide more stable performance in demanding service conditions.
Fuel and Oil Resistance
Viton tubing helps maintain its structure when exposed to many fuels, oils and lubricants. This makes it suitable for selected fuel lines, oil circuits and engine-related fluid paths.
Chemical Compatibility with Selected Media
Viton tubing offers good resistance to many fuels, oils and selected chemical media. However, compatibility is not determined by the material name alone.
Before production, the compound should be confirmed against the actual fluid, concentration, temperature, pressure and contact time. This review helps determine whether the selected Viton grade can maintain its flexibility, sealing performance and dimensional stability in the customer’s application.
Low Permeation
The fluoroelastomer structure can help reduce the passage of fuel vapors and selected gases through the tube wall. This is valuable where emissions, odor, fluid loss or vapor transmission must be controlled.
Actual permeation performance depends on the FKM grade, fluorine content, wall thickness, medium and temperature.
Temperature and Weather Resistance
Viton tubing provides useful resistance to temperature variation, weathering and ozone exposure when the appropriate compound grade is selected. It can be considered for exposed equipment and demanding industrial environments where ordinary rubber may age more quickly.
The actual continuous operating temperature, short-term temperature limit and outdoor suitability must be confirmed according to the specific formulation, wall thickness and service conditions.
What Is Viton Tubing Application?
Viton tubing is used when the tube must maintain a reliable fluid path while exposed to demanding media or operating conditions. The correct FKM grade and tube construction should always be selected according to the actual application
Vacuum Equipment and Reduced-Pressure Systems
Viton tubing is used in selected fuel lines, fuel transfer assemblies and engine-related fluid paths. Its main function is to transport fuel while helping resist fuel exposure and vapor permeation.
During design, confirm the fuel type, working temperature, pressure and required tube dimensions. During installation, avoid excessive bending, sharp edges and connection stress that may damage the tube.
Vacuum Equipment and Reduced-Pressure Systems
Viton vacuum tubing is used between vacuum equipment, fittings and reduced-pressure fluid paths. Its function is to maintain a stable passage while limiting leakage and tube deformation.
The design should consider vacuum level, wall thickness, hardness and bend radius. During installation, the tube should be routed without sharp kinks and connected with fittings that provide even compression.
Chemical Dosing and Fluid Transfer
Viton tubing is used in selected chemical dosing lines and fluid transfer systems. Its role is to carry the chemical medium while maintaining dimensional stability and flexibility under the specified conditions.
Before production, confirm the chemical type, concentration, temperature and contact time against the selected FKM compound. During installation, prevent contamination, over-compression and contact with incompatible sealing materials.
Industrial Equipment and Exposed Fluid Paths
Viton tubing is used in industrial equipment where fuel, oil, selected chemicals, temperature variation or outdoor exposure may occur. Its function is to provide a flexible and controlled fluid path around equipment components.
Designers should check routing space, fitting position, movement and maintenance access. During installation, keep the tube away from abrasion, excessive heat sources and unnecessary tension.
Custom Viton Tubing Built Around Your Fluid Path
Viton tubing should be customized according to the actual medium, operating conditions and installation space. We review the application first, then determine the appropriate FKM compound and tube dimensions.
Tube Dimensions and Flow Requirements
We can develop the required inner diameter, outer diameter, wall thickness and cut length around the customer’s flow path. Dimensions should provide sufficient flow capacity while fitting the available installation space and connection method.
Compound Selection for the Actual Medium
The Viton compound is selected according to the fuel, oil, chemical or gas being transported. Compatibility review considers the medium type, concentration, temperature, pressure and contact time.
This step helps prevent unnecessary swelling, hardening, softening or excessive permeation during service.
Flexibility, Bend Radius and Routing
The tube design is reviewed according to the required bend radius, movement and routing direction. This helps reduce kinking, flattening and stress at fittings during installation or equipment operation.
Compound and Dimension Sample Approval
For new Viton tubing designs, a sample can be developed for evaluation in the customer’s actual assembly. The sample approval stage helps confirm chemical compatibility, fit, flexibility and installation performance before repeat production.
