Size reference
FEP Rod Reference Sizes
The original individual-size data has been grouped by reference length so buyers can compare the practical diameter range more quickly.
| Reference Length | Nominal Diameter Options | Supply and Machining Note |
|---|---|---|
| 540 mm | 9, 13, 16, 20, 25, 30, 35 mm | Long pressed rods; allow for ovality and finishing stock |
| 100 mm | 27, 32, 37, 42, 47, 52, 57, 62, 65, 70, 72, 75, 78, 83, 96, 109, 125, 130 mm | Short blanks for machining and prototypes |
Dimensional notice: The listed FEP rod diameters are reference tool dimensions. Actual semi-finished dimensions may be approximately 1.2% smaller due to material shrinkage. Confirm finished diameter, machining allowance, straightness, ovality, length, quantity, grade, and inspection requirements before ordering.

Frequently asked questions
FEP rod FAQ
What should buyers verify when choosing a FEP rod manufacturer?
Confirm the resin or compound, manufacturing route, dimensional tolerance, inspection method and batch traceability. The drawing and service conditions should be reviewed before price becomes the deciding factor.
What information should I send to a FEP rod supplier?
Send the required grade, dimensions, tolerance, quantity, operating temperature, chemical media, mechanical load, documentation and delivery destination. Photos or drawings help prevent quotation assumptions.
Can the JIAFUXIN FEP rod factory make custom sizes?
Custom dimensions and secondary processing can be reviewed from a drawing, sample or application specification. Feasibility depends on the material, production method, tolerance and order volume.
Are FEP rod rod and bar the same product?
Rod and bar are often used interchangeably for round stock. The purchase specification should define diameter, length, straightness, ovality, grade and machining allowance.
What is the difference between FEP and PFA?
FEP and PFA are melt-processable fluoropolymers with strong chemical resistance. FEP is often more flexible and transparent, while PFA is generally preferred at higher temperatures and in demanding high-purity systems. See the FEP material guide.
Is FEP considered Teflon?
FEP is a fluoropolymer and may be sold under fluoropolymer trade-name families, but FEP and PTFE are different polymers. Purchase specifications should use the generic material and grade.
How do I select the right FEP rod for my application?
Select FEP rod by diameter, straightness, concentricity, material grade, filler and finished-part tolerance. Final suitability depends on the complete operating environment and required service life.
How much machining allowance is needed on FEP rod?
Allowance depends on rod diameter, straightness, ovality, finished tolerance and whether stress relief is required. Send the finished drawing so stock size can be selected correctly.
