Chemical-Resistant PVC Tubes

When working near chemicals such as acids and alkalies, these tubes offer 360° protection to wires, cords, and anything that can slide through them. They’re made of PVC Type 1, a material that’s easy to thermoform, plus it is an excellent insulator. These tubes are oversized on the outside and undersized on the inside to allow for finishing to the sizes listed.

Low-Carbon Steel Rectangular 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 fixture clamps, mounting plates, and spacers. This material can be surface hardened with heat treating.

Ultra-Formable 260 Brass Rectangular Tubes

Yield Strength: Not Rated
Hardness: Not Rated
Temper: H02 (1/2 Hard) to H03 (3/4 Hard)
Heat Treatable: No
Specifications Met: ASTM B135

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware. Each tube fits inside the next larger size for creating telescoping tubes.

Arc-Resistant GPO3 Fiberglass Square Tubes

Color: Red
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: Barcol 50 (Hard)
For Use Outdoors: No
Specifications Met: UL 94 V-0

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.

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.

Easy-to-Machine Garolite LE Rectangular Tubes

Color: Brown
Max. Temperature: 235° F
Tensile Strength: 6,000-15,300 psi (Good)
Impact Strength: 1-1.25 ft.-lb./in. (Poor)
Hardness: Rockwell M105
For Use Outdoors: Yes

Easily turn these rectangular tubes into parts for transformers and switchgears using high-speed tooling. Made with cotton fabric reinforcement, they’re also good for crafting intricate items—from fine-tooth gears to control boards. Though easier to machine, these tubes are not as strong as those with glass cloth or paper reinforcement. Garolite LE is also called industrial laminate and phenolic.
