Smooth-Bore Seamless Stainless Steel Tubing
Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
304 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.
- Temperature Range:
304 Stainless Steel: -425° to 1500° F
316 Stainless Steel: -325° to 1500° F - Bending Method: Tube Bender
- For Use With: Natural Gas, Water, Oil, Air
- Compatible Tubing Fittings: Butt Weld, Compression, Flared, and Yor-Lok
Welded Stainless Steel Tubing
When your application does not require a smooth interior, this tubing is an economical choice. It has a weld bead on the inside.
304 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
- Temperature Range: 304 Stainless Steel: -420° to 1500° F
316 Stainless Steel: -320° to 1500° F - Bending Method: Tube Bender

Low-Carbon Steel Round Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit. This steel is manufactured to ASTM, SAE, or EN standards for quality and performance.
Easy-to-Weld 4130 Alloy Steel Round Tubes
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See table
- Fabrication: Seamless
- Specifications Met: See table
Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating. These tubes have been manufactured to SAE and military standards for quality and performance.

High-Strength 2024 Aluminum Tubes
- Yield Strength: 42,000 psi
- Hardness: Brinell 120 (Medium)
- Temper: T3
- Fabrication: Cold Drawn
- Specifications Met: ASTM B210
While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Multipurpose 304 Stainless Steel
From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
304/304L stainless steel contains less carbon than standard 304 for better weldability.
Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.

Electrical-Insulating Tube Sleeving
Add a layer of insulation to prevent electricity and heat from dissipating from wire and cable. This sleeving is often used in motors, transformers, and generators. Made of coated fiberglass, it resists abrasion, acids, alkalies, and chemicals.
Vinyl-coated sleeving resists wax and alcohol. Sleeving is flame-rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.
High-Temperature Electrical-Insulating Tube Sleeving
This sleeving is often used to insulate connections in transformers, relays, and solenoids. It prevents electricity and heat from dissipating from wire and cable. When exposed to flame, it will self-extinguish and produce a nonconductive ash. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material. Made of silicone-coated fiberglass, it resists chemicals.
Expandable Electrical-Insulating Tube Sleeving
A specially formulated silicone rubber coating allows this fiberglass sleeving to stretch over items during installation; it then tightens around its contents for a secure fit. Often used in motors, generators, and transformers, it prevents electricity and heat from dissipating from wire and cable. It has good chemical resistance.
Round Adjustable-Length Shipping Tubes
Adjust these tubes by twisting the two halves. A hexagonal end prevents rolling. Use them to protect long, thin objects during shipping.
Twist-to-lock tubes can be slid up or down to adjust their length, so you don’t have to repeatedly twist the two pieces. To slide, turn the top tube into the sliding channel. To lock, turn the tube with the ridges into the grooved channel.
Recycled Plastic Round Adjustable-Length Shipping Tubes
Made of recycled polyethylene, these shipping tubes are more sustainable than standard plastic shipping tubes. Push the ends together or pull them apart to adjust the length. Use these tubes to protect long, thin objects during shipping.
