Size reference
PFA 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 |
|---|---|---|
| 1000 mm | 20, 30, 40, 50, 100 mm | Long rods for cutting and machined components |
| 540 mm | 9, 13, 16, 20, 25, 30, 35, 40 mm | Pressed rods; allow for center seam or ovality |
| 150 mm | 27, 32, 37, 42, 47, 52, 57, 62, 65, 70, 72, 75, 78, 83 mm | Medium-length machining blanks |
| 100 mm | 96, 109, 125, 130, 176 mm | Large-diameter machining blanks |
| 50 mm | 250 mm | Extra-large-diameter short blank |
Dimensional notice: The listed PFA 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
PFA rod FAQ
What should buyers verify when choosing a PFA 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 PFA 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 PFA 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 PFA 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 PFA and PTFE?
Both provide broad chemical resistance and high-temperature capability. PFA is melt processable and easier to extrude or weld, while PTFE offers a wider range of molded, skived and filled stock forms. Review the PFA material guide.
Is PFA better than FEP for high-temperature service?
PFA generally supports a higher continuous service temperature, while FEP is often selected for flexibility, clarity and lower-temperature applications. Pressure, purity and fabrication requirements also matter.
How do I select the right PFA rod for my application?
Select PFA 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 PFA 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.
Which PFA rod grade is best for wear or load?
Compare unfilled and reinforced grades against load, speed, counterface, lubrication, temperature and chemical media. A stronger grade is not automatically the best option for every bearing or seal.
