Chemical Tubing

Extreme-Temperature Hard
Plastic Tubing for Chemicals

Run chemicals through this tubing at temperatures between -100° F and 500° F.

UV-Resistant Hard Plastic Tubing for Chemicals

Ultraviolet light won’t cause this tubing to degrade or deteriorate.

Crack-Resistant Hard Plastic Tubing for Chemicals

You don’t have to worry about this tubing cracking due to stress or impact—even over a wide range of temperatures.

Soft Plastic Tubing for Chemicals

Use this general purpose tubing with a variety of chemicals.

High-Temperature Soft Rubber Tubing for Chemicals

Use this resilient tubing in high-temperature chemical applications up to 400° F.

Abrasion-Resistant Soft
Rubber Tubing for Chemicals

With excellent resistance to abrasion and tearing, this tubing can hold up in rugged environments.

Low-Temperature Firm Plastic Tubing for Chemicals

Cold temperatures pose no problems for this tubing—it stays strong and flexible, even when temperatures drop to -100° F.

Food, Beverage, and Dairy Tubing

Soft Plastic Tubing for Food, Beverage, and Dairy

The industry standard for general purpose food, beverage, and dairy applications, this tubing meets NSF/ANSI Standard 51 for food contact.

High-Temperature Abrasion-Resistant Soft
Rubber Tubing for Food, Beverage, and Dairy

Not only can this tubing handle the highest temperatures of all our soft tubing for food, beverage, and dairy, it also has superior abrasion and crush resistance. Use in applications up to 450° F.

High-Temperature Soft Rubber
Tubing for Food and Beverage

Hot food and beverage applications won’t harm this tubing—it can handle temperatures up to 390° F.

Abrasion-Resistant Firm Plastic and
Rubber Tubing for Food and Beverage

Tough and durable, this tubing resists abrasion and tearing.

Soft Tubing for Fuel and Lubricants

Soft Plastic Tubing for Fuel and Lubricants

The industry standard for fuel and lubricant applications, this tubing can be used intermittently with petroleum-based products without becoming hard or brittle.

High-Temperature Soft Rubber
Tubing for Fuel and Lubricants

This tubing can handle the highest temperatures of all of our fuel and lubricant tubing. Use it in applications up to 450° F.

Abrasion-Resistant Soft Rubber Tubing for Fuel

This tubing is soft enough to handle continuous bending and flexing, yet tough enough to resist tearing and abrasion.

Firm Plastic and Rubber Tubing for Drinking Water

Tubing meets NSF/ANSI Standard 61 for drinking water.

Metal Tubing for Flow

Smooth-Bore Seamless Stainless Steel Tubing

This tubing has a seamless construction with no weld bead for unrestricted flow and is stronger than welded tubing.

Welded Stainless Steel Tubing

When your application does not require a smooth interior, this tubing is an economical choice.

General Purpose Aluminum Tubing

Aluminum tubing is lightweight with good corrosion resistance and weldability.

Brass Tubing

A soft metal frequently used with air, gasoline, natural gas, propane, and plumbing applications. Tubing is not as corrosion resistant as stainless steel.

Smooth-Bore Seamless Steel Tubing

Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It can be flared without splitting.

Tube Fittings for Plastic and Rubber Tubing

Tube Supports for Brass Compression
Tube Fittings for Air and Water

Tube supports slip inside tubing to prevent the walls from collapsing.

Brass Compression Tube Fittings for Air and Water

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Tight-Seal Plastic Barbed
Tube Fittings for Air and Water

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Tight-Seal Moisture-Resistant Plastic
Barbed Tube Fittings for Air and Water

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Super-Flow Plastic Barbed Tube
Fittings for Food and Beverage

A smooth interior reduces friction and prevents product buildup, ensuring an unrestricted flow.

Barbed Fittings for Plastic and
Rubber Tubing—Chemicals

Fittings have a barb that grips onto tubing. Use in applications up to 120 psi.

Push-to-Connect Tube
Fittings for Hot Drinking Water

Fittings can withstand temperatures up to 200° F.

Raw Materials

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.

Ultra-High-Temperature Quartz Glass Tubes

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack.

Hollow Linear Motion Shafts

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.
