Combining the heat resistance of metal with the flexibility of fabric, this fiberglass hose has a special coating that stands up to high temperatures.

Blo-R-Vac Flexible Duct Hose for Dust

A good general purpose hose for blowing and vacuum applications, this hose is for use with grinding dust, sawdust, and lint.

High-Temperature Flexible Duct Hose for Dust

The neoprene coating on this hose holds up under high heat.

Static-Control Very Flexible Duct Hose for Dust

The neoprene coating on this hose contains carbon to dissipate static when hose is installed in a grounded system.

Extra-Strength High-Vacuum Duct
Hose for Metal Chips and Shavings

The strongest rubber duct hose we offer, this SBR (styrene butadiene rubber) hose is reinforced with yarn and has a metal spiral.

Metal

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.

Easy-to-Machine Gray Cast Iron Round Tubes

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

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.

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Multipurpose 6061 Aluminum Round Tubes

The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

High-Strength 2024 Aluminum Tubes

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.

Weldable 954 Bearing Bronze Tubes

954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears. The strength of this material increases with heat treating.

Easy-to-Machine 936 Bearing Bronze Tubes

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

Plastic

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.

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.

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.

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.

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.

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.

Hook-and-Loop Wrap-Around Sleeving

A strip of hook-and-loop creates a strong seal along the entire length of this sleeving, yet it can be opened at any point to access contents. Use it to wrap around wire, cable, or hose without disconnecting them.

Pipe Insulation

Flexible Rubber Foam Pipe Insulation

Soft and easy to install, this insulation restricts absorption of water, air, and gas. It is often used on cold and hot water lines and refrigeration lines.

Mineral Wool Pipe Insulation

These insulation tubes and sheets meet ASTM E84 standards for flame and smoke.

Fiberglass Pipe Insulation

This common insulation material is typically used on hot and cold water lines and in process piping.

Lightweight Melamine Foam Pipe Insulation

Melamine has a lightweight construction that allows quick and easy installation. Use on cold and hot water piping and with refrigeration systems.

Clean Room Melamine Foam Pipe Insulation

These rigid, lightweight melamine foam tubes are wrapped in an ISO Class 5 and Fed. Spec. Class 100 clean room jacket that is suitable for sanitary and washdown applications. They’re typically used on cold and hot water piping and with refrigeration systems.

Chemical-Resistant Cellular Glass Pipe Insulation

Very rigid with a 0% water absorption rate, this insulation is unaffected by corrosive environments, organic solvents, and most acids. It is typically used in chemical-processing systems and underground lines.

Ultra-Insulating Low-Temperature
Polyisocyanurate Foam Pipe Insulation

This very rigid insulation offers the lowest heat-flow rate of our pipe insulation and restricts absorption of water, air, and gas. It is typically used in process piping and chiller plants and performs best in applications below 50° F.

Pipe Insulation Banding

Save installation time with banding that’s ready to use. It has an easy-to-close fastener on one end.
