About Plastic

High-Temperature Foam Tubes

Multipurpose Blended Neoprene Foam Tubes

Neoprene is blended with EPDM and polyethylene for foam tubes that offer good resistance to water, sunlight, and oxidation.

Ultra-Weather-Resistant EPDM Foam Tubes

These EPDM foam tubes have the best resistance to water, sunlight, and oxidation of all the foam tubes we offer.

Composites

Multipurpose Flame-Retardant
Garolite G-10/FR4 Tubes

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

Economical Electrical-Insulating Garolite XX Tubes

Stronger than Garolite CE with better electrical-insulating properties, Garolite XX is often fabricated into low-cost electrical components.

Ultra-High-Temperature
Impact-Resistant Garolite Tubes

Used in turbine bearings, downpipe gaskets, and other machinery, these Garolite tubes withstand heavy impacts and temperatures as high as 500° F.

Flame-Retardant High-Temperature
Garolite G-11/FR5 Tubes

A flame-retardant version of Garolite G-11, these tubes are commonly used to make bushings, standoffs, and spacers for areas with high temperatures. All are stronger and resist heat better than Garolite G-10/FR4.

Easy-to-Machine Garolite LE Tubes

Using nothing more than standard high-speed steel tooling, Garolite LE can be machined into intricate parts.

Economical Garolite CE Tubes

Garolite CE is often fabricated into parts where high strength is not required.

Halogen-Free Garolite G-10 Tubes

Use Garolite G-10 in place of Garolite G-10/FR4 for applications that are sensitive to halogen, such as in nuclear plants. It's strong, machinable, and electrically insulating.

Ultra-Low-Temperature Garolite G-10 CR Tubes

Rated for temperatures down to -450° F, this Garolite G-10 CR performs better in cryogenic applications than other glass epoxies.

Electrical-Insulating Garolite XXX

More electrically insulating than Garolite XX, these tubes are often machined into insulating washers, bushings, transformer spacers, and parts of terminal boards.

Arc-Resistant GPO3 Fiberglass Round Tubes

Use these round GPO3 fiberglass tubes for electrical applications in humid environments.

Plastic

Chemical-Resistant Slippery PTFE Tubes

Known for its naturally slippery surface, PTFE surpasses most plastics when it comes to chemical resistance and performance in extreme temperatures.

Wear- and Chemical-Resistant PEEK Tubes

Not only does PEEK provide superior wear resistance in repetitive processes, it is also resists wear caused by abrasion. PEEK can be used as a lightweight substitute for metal parts in chemical-processing applications.

Slippery UHMW Polyethylene Tubes

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Chemical-Resistant PVC Tubes

Because PVC resists many acids and alkalies, it’s widely used for tanks and in chemical-processing applications. Also known as PVC Type 1.

High-Temperature CPVC Tubes

CPVC is just as chemical resistant as standard PVC Type 1 and can handle hotter temperatures up to 200° F.

Wear-Resistant Easy-to-Machine
Delrin® Acetal Resin Tubes

Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Slippery Wear-Resistant Easy-to-Machine
Delrin® Acetal AF Resin Tubes

The addition of PTFE provides a more slippery, wear-resistant surface than standard Delrin® acetal resin. It’s commonly fabricated into pump components, gears, and bearings.

Wear-Resistant Nylon Tubes

Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

Oil-Filled Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

This nylon stays lubricated over time because it’s filled with oil. Use it to fabricate parts for hard-to-reach places where adding lubricants would be difficult.

MDS-Filled Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

The addition of MDS gives these tubes exceptional wear resistance along with a self-lubricating surface. They're made of cast nylon 6, making them easier to machine and better electrical insulators than other MDS-filled nylon tubes.

Heat-Stabilized Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

A good choice for making sprockets and pulleys, these cast nylon 6 tubes withstand higher temperatures and are easier to machine than standard nylon 6/6 tubes.

Easy-to-Machine Wear-Resistant Cast Nylon Tubes

This cast nylon 6 material is easier to machine than other types of nylon. It’s comparable to Nylatron and Nycast.

Wear-Resistant Easy-to-Machine Acetal Tubes

An economical alternative to Delrin® acetal resin, this acetal copolymer offers similar wear resistance.

Impact-Resistant Easy-to-Form ABS Tubes

Because ABS maintains its toughness even after thermoforming, it’s often made into storage cases, tote trays, equipment housings, and protective gear.

Polypropylene Tubes

Because this polypropylene resists swelling when exposed to water, it’s often fabricated into containers and parts for laboratory equipment.

Clear Scratch- and UV-Resistant Cast Acrylic Tubes

Cast acrylic is easier to machine than extruded acrylic. It's comparable to Lucite and Plexiglas® Acrylic.

Clear Scratch- and UV-Resistant Acrylic Tubes

This extruded acrylic offers similar performance as cast acrylic at a lower cost.

Clear Impact-Resistant Polycarbonate Tubes

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.

Clear Easy-to-Form PETG Tubes

PETG can be formed into complex shapes without sacrificing durability.

Clear Cellulose Tubes

Widely used as shipping tubes, this cellulose is also known as butyrate.

Ultra-High-Temperature Ceramic

Thermally Shock-Resistant Mullite Ceramic Tubes

Protectively sheath materials, such as thermocouples, that move between hot and cold environments. Similar to nonporous alumina tubes, air and gas cannot pass through these mullite tubes.

Extra Thermally Shock-Resistant
Single-Closed-End SiAlON Ceramic Tubes

Often used as a protective shield in thermocouples and other conditions with drastic climate changes, these SiAlON ceramic tubes won't deform, expand, or crack when repeatedly exposed to large temperature changes.

Rubber

Weather-Resistant EPDM Rubber Tubes

Used to seal narrow spaces such as channels, these tubes offer more compression than solid EPDM rods.

Multipurpose Neoprene Rubber Tubes

Jackets, seals, and insulation are just a few of the many uses for rubber tubes.
