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.

- Temperature Range: 5° to 140° F
- Tensile Strength: 7,000-7,800 psi (Good)
- Impact Strength: 0.7-3 ft.-lbs./in. (Poor)
- Hardness: Rockwell R110-R120 (Hard)
- For Use Outdoors: No
- Specifications Met: UL 94 V-0

Low-Carbon Steel Rectangular Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways. To increase their wear resistance, you can surface harden them with heat treating. These tubes are manufactured to ASTM or EN standards for quality and performance.

- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C49
- Fabrication: Seamless
- Specifications Met: MIL-T-6736, SAE AMS-T-6736
Made from 4130 alloy steel, also known as chrome-moly steel, these tubes have low carbon content for good weldability. They’re often used for building frames and supports, since their flat sides make them easier to bolt than round tubes. 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.

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.
