Manufacturing Methods & Specifications

Molded vs Extruded PTFE Tube — Side-by-Side Comparison

Choosing the right manufacturing method matters. Molded hollow bar is compression-formed for thick walls and isotropic strength — the go-to choice for large bushings and vessel liners. Extruded tubing is ram-extruded for continuous lengths and thin walls — the preferred option for fluid handling and small rings. With both processes in-house, we help you select the optimal product for your application without bias toward either method.

Enhanced Performance Grades

Modified & Filled PTFE Tube — Engineered Compounds

Beyond pure virgin-grade material, we also mold and extrude filled tube stock with performance-enhancing additives. Each filler targets specific property improvements — wear resistance, thermal conductivity, creep resistance, or friction reduction — for demanding industrial bushings, wear rings, and machined components.

Bronze Filled PTFE Tube

Copper-tin bronze powder. Highest load-bearing capacity, excellent thermal conductivity. For heavy-load bushings, wear rings, and high-pressure piston guide rings.

Graphite Filled PTFE Tube

Flake graphite powder. Lowest friction coefficient, self-lubricating. For dry-running bushings, compressor rider rings, and sliding wear components in non-lubricated service.

Carbon Fiber Filled PTFE Tube

Chopped carbon fiber reinforcement. Superior creep resistance, high compressive strength, excellent dimensional stability. For structural bushings and high-temperature valve components.

Glass Fiber Filled PTFE Tube

Milled glass fiber reinforcement. Best wear resistance, low creep, excellent chemical compatibility. Most common filled PTFE tube — cost-effective for hydraulic bushings and seal rings.

Polyimide (PI) Filled PTFE Tube

Vespel-style polyimide filler. Lowest friction among filled grades, non-abrasive to soft mating surfaces. FDA-compliant, ideal for food-grade and pharmaceutical machinery bushings.

POB (Ekonol) Filled PTFE Tube

Aromatic polyester resin filler. Excellent high-temperature wear resistance, non-abrasive, FDA-compliant. For chemical pump wear rings and rotary shaft bushings.

Glass Microsphere Filled PTFE Tube

Hollow borosilicate glass microspheres. Reduced density, improved compressive strength, lower cold flow. Visually identifiable blue color. For sanitary flange bushings and chemical pipe liners.

MoS₂ Filled PTFE Tube

Molybdenum disulfide powder. Ultra-low friction, enhanced wear resistance, improved non-stick properties. For boundary-lubricated and dry-running dynamic seal bushings.

PTFE Tube Applications

Where PTFE Tube Is Used

PTFE Tube for Large Bushings & Wear Rings

Thick-wall molded hollow bar machined into wear rings, guide rings, and bushings for pumps, compressors, and rotating equipment — delivering chemical resistance and low friction for demanding industrial applications.

PTFE Tube for Chemical Pipe Liners

Custom-molded liners inserted into steel pipes for corrosive chemical transport. Isotropic structure ensures uniform chemical resistance throughout the wall thickness — complete protection against aggressive media.

PTFE Tube for Electrical Insulation Sleeves

Extruded tubing used as high-temperature electrical insulation sleeves, wire guides, and probe protectors in semiconductor and analytical instrument applications where dielectric performance is critical.

PTFE Tube for Fluid Handling Tubing

Long continuous lengths of extruded tubing for chemical transfer lines, laboratory fluid paths, and medical device applications — zero contamination, ultra-pure, and non-reactive for the most sensitive fluid handling.

PTFE Tube for Semiconductor Wet Bench Plumbing

Ultra-pure virgin-grade tubing for chemical delivery lines, drain plumbing, and DI water distribution in semiconductor wet benches and wafer cleaning tools — zero metal ion leaching.

PTFE Tube for Laboratory Gas & Fluid Lines

Inert fluoropolymer tubing for analytical instrument gas delivery, chromatography sample lines, and laboratory chemical transfer — zero media absorption, no cross-contamination.

Why Our PTFE Tube

Two Methods, One Quality Standard

As a specialized manufacturer and supplier, we do not simply stock off-the-shelf sizes — we produce custom hollow bar to your exact specifications. Whether your project calls for a thick-wall bushing tube for a pump rebuild or long spools of extruded tubing for an OEM fluid system, our dual-process capability in molded and extruded manufacturing ensures you get the right product for the job, not a compromise.

Thick-Wall Capability

Our compression molding process handles wall thicknesses from 3mm up to 200mm — ideal for large bushings and structural liners that extruded tube cannot match.

Long Continuous Lengths

Ram-extruded tubes up to 3000mm in a single piece reduce joints in fluid handling systems and maximize parts-per-length on your CNC lathe.

Custom ID/OD Combinations

Need a specific inner and outer diameter combination? We mold and extrude to your exact ID/OD requirements — not just what is in a catalog.

Tight Wall Tolerance

Extruded tube achieves ±0.10mm on OD and ±0.15mm on ID. Molded tube held to ±0.20mm. For tighter tolerances, we offer finish-machined tube.

Common Questions

PTFE Tube Manufacturing FAQ

Molded vs extruded PTFE tube — which should I choose? +

Choose compression-molded hollow bar when you need large OD (above 300mm), thick walls (above 3mm), or isotropic properties for critical structural components like bushings and vessel liners — this process delivers uniform density throughout the blank. Choose ram-extruded tubing for continuous lengths up to 3000mm, thinner walls down to 1.5mm, tighter tolerances, and fluid handling applications — this method excels where long uninterrupted runs matter. Share your OD, ID, and length requirements and we will guide you to the right manufacturing approach for your project.

What is the maximum outer diameter PTFE tube you can make? +

Compression-molded tube can be produced up to 800mm OD — this capacity covers most industrial bushing and liner requirements. Ram-extruded hollow bar goes up to 300mm OD — ideal for smaller-diameter fluid and electrical applications. For very large diameters above 800mm, we can custom-mold individual billets. Contact us with your requirements and we will find the right solution.

What is the minimum wall thickness you can achieve? +

Ram-extruded hollow bar can achieve wall thickness as thin as 1.5mm — this makes it the perfect choice for lightweight fluid handling and electrical insulation sleeve applications. Compression-molded stock requires a minimum wall of 3mm due to the nature of the molding process, which ensures structural integrity in every piece. For walls thinner than 1.5mm, consider heat-shrink tubing or paste-extruded thin-wall tubing, both of which we can also supply.

Can you supply custom inner diameters? +

Yes. We manufacture tube stock to your specified ID/OD combination. For the molded process, the ID is formed by a mandrel during compression. For extruded production, a die and mandrel set produces your exact dimensions. We can hold ID tolerance to ±0.15mm for extruded hollow bar and ±0.20mm for molded tube stock. Need tighter? Ask about our finish-machined option.

What length options are available for PTFE tube? +

Molded hollow bar is available up to 1500mm in length. Extruded tubing can be supplied up to 3000mm in a continuous piece — these long uninterrupted lengths reduce joints in your fluid systems. We also provide cut-to-length service for both types — order by the piece in your exact required length. Standard stock lengths are 500mm and 1000mm, with custom cuts available on request.

What is the minimum order quantity for custom PTFE tube? +

For standard sizes in stock, MOQ is 1 meter or 1 piece. For custom OD/ID combinations, MOQ is typically 10 kg. For very large diameters (above 500mm OD), MOQ may be 25 kg. We accommodate prototype and small-batch orders — contact us with your dimensions for a specific quote.
