Arc-Resistant GPO3 Fiberglass Round Tubes

Color: Black
Temperature Range: -50° F to 265° F
Tensile Strength: 10,000-15,000 psi (Good)
Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
Hardness: Rockwell M95 (Hard)
For Use Outdoors: No

Use these round GPO3 fiberglass tubes for electrical applications in humid environments. They are arc and track resistant, plus they have better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're also called polyester-grade industrial laminate.

Route and insulate wire using these square fiberglass tubes, which fit better along edges and around corners than round tubes. Use them for electrical applications in humid locations. They’re arc and track resistant, and better electrical insulators than FRP fiberglass. Made of fiberglass-reinforced polyester, they’re also known as polyester-grade industrial laminate.

Ultra-Strength Lightweight Carbon Fiber Round Tubes

Made of carbon fiber, these are the strongest composite round tubes we offer. Carbon fiber is comparable in strength to 6061 aluminum yet lighter in weight. These round tubes are often used to build frames and structures.

Plain tubes have a 0° construction layup, which means their fibers are aligned in a single direction for linear strength and rigidity. They resist bending but will crush easily if impacted. They’re often used to support structures.

Checked tubes have a 0°/90° construction layup, which means their fibers are aligned in two directions to resist crushing and twisting better than plain tubes. Their checked appearance is the most common design for carbon fiber.

Glossy tubes reflect light and can be modified with a clear coat or sanded down for a matte finish.

Matte tubes don’t reflect light and can be painted without any prep work. They’re often used in photography applications.

Telescoping Ultra-Strength Lightweight Carbon Fiber Hexagonal Tubes

Fiber Tensile Stiffness: Standard (33-36 msi)
Impact Strength: Not Rated

For Use Outdoors: No

These tubes are stiff and have tensile strength comparable to aluminum—but are still lightweight—and can be placed inside one another to create an adjustable-length tube that resists twisting. Because they have flat sides, they’re easier to mount than round tubes. Use them to support moving equipment such as cameras and sensors. Built with a 0°/90° construction layup, they’re crush resistant and good for transferring torque. These tubes have a checked, glossy exterior, the standard for carbon fiber. They can be given a clear coat or sanded down for a matte finish. All tubes are roll wrapped.

For secure telescoping, choose a tube one size larger than the tube you’ll put inside it.

Rigid Ultra-Strength Lightweight Carbon Fiber Round Tubes

Color: Black
Temperature Range: -65° F to 180° F
Tensile Strength: 125,000-175,000 psi (Excellent)
Fiber Tensile Stiffness: High Modulus (57-63 msi)
Impact Strength: Not Rated
Hardness: Not Rated
For Use Outdoors: No

Over twice as stiff as aluminum, these high modulus carbon fiber tubes resist bending. They’re often used in instrumentation and other precision applications that require a rigid, high-strength, lightweight material. Built with a 0°/90° construction layup, they’re crush resistant and good for transferring torque. A checked, glossy finish gives them a standard carbon fiber appearance. You can also give them a clear coat or sand them down for a matte finish that won’t reflect light.

Impact-Resistant High-Strength Carbon Fiber Round Tubes with Kevlar Core

Color: Black
Max. Temperature: 140° F
Tensile Strength: 85,000 psi (Excellent)
Impact Strength: Not Rated
Compressive Strength: 60,000 psi
Hardness: Not Rated
For Use Outdoors: Yes

Often used to build frames and structures, these tubes combine the strength and stiffness of carbon fiber with the impact and puncture resistance of Kevlar. The carbon fiber layers are comparable in strength to 6061 aluminum, so they resist deforming from stretching and crushing, yet are lighter in weight. A Kevlar core reinforces these tubes, while also making them weigh less than tubes made entirely of carbon fiber. However, they have a 40% lower tensile strength than all-carbon-fiber tubes. These tubes require tools such as a carbide or waterjet cutting tool for machining.

Multipurpose Flame-Retardant Garolite G-10/FR4 Rectangular Tubes

Color: Green
Maximum Temperature: 265° F
Tensile Strength: 32,000-40,000 psi (Excellent)
Impact Strength: 5.5-12 ft.-lbs./in. (Excellent)
Hardness: Rockwell M100 (Extra Hard)
For Use Outdoors: Yes
Specifications Met: MIL-I-24768/27

These rectangular tubes are flame retardant, machinable, and electrically insulating. They’re made of epoxy resin, making them good for use with printed circuit boards, insulating washers, and transformer components. With low moisture absorption, these tubes are often used as thermal insulators. Made with fiberglass fabric reinforcement, they’re strong and easier to machine than other glass cloth phenolics. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.
