Speedway Motors Round 1020 DOM Steel Roll Cage Tubing
Overview: Constructed from 1020 DOM (Drawn Over Mandrel) steel, this tubing provides reliable strength with uniform wall thickness. It is sized for common motorsport fabrication needs, with a 1.75-inch outside diameter and a .095-inch wall thickness. Pre-cut length options help tailor pieces for chassis, roll bars, bumpers, and other structural components. DOM steel is favored for its balance of ductility and strength, enabling precise welding and fabrication work in high-stress environments.
A36 Hot Rolled Carbon Steel Square Tubing
Overview: A36 carbon steel is a widely used structural steel known for good formability and weldability. This hot-rolled square tubing measures 1 3/4 inches on each side with a thickness of 0.120 inches and a 72-inch length, making it suitable for frames, supports, and light-to-medium load applications. It is well-suited for welding, drilling, machining, and forming, whether used in fabrication shops or DIY projects. The square profile offers predictable strength in multiple directions for rigid builds.
DERPIPE Soft Braided PVC Tubing
Overview: This 3/4-inch ID, 1-inch OD braided PVC tube is 10 feet long and reinforced for high-pressure applications. The braided construction increases tensile strength and helps resist kinking, while the smooth interior eases flow and flushing. The tubing is BPA- and phthalate-free, non-toxic, and designed for use across seasons. It’s well-suited for water, oil, or light industrial transfer tasks where flexibility and durability matter.
DERNORD PVC Tubing
Overview: DERNORD PVC tubing offers 3/4 inch ID by 1 inch OD with a 10-foot length. Designed for general industrial use, it supports liquids and semi-solids and is compatible with common barbed fittings. The tubing emphasizes smooth interior and exterior surfaces to minimize sediment buildup and ensure easy cleaning, making it a practical option for low- to moderate-pressure fluid transfer tasks.
Macepason Clear Vinyl Tubing
Overview: Clear vinyl tubing offers 3/4 inch ID and 1 inch OD in 10-foot lengths. It is described as clear, flexible, and soft, with a hardness around 73A. Suitable for low-pressure applications such as air, water, or light oil transport, the transparency allows easy observation of flow. The tubing is designed for general purpose use where visibility and bendability are valuable.
QuQuyi Heavy-Duty Steel Wire Suction Tubing
Overview: QuQuyi presents a 3/4 inch ID by 1 inch OD heavy-duty PVC suction tubing, designed for high-pressure UV chemical resistance and durable vinyl construction. Although the length is shorter (about 1.3 feet), this option is suited for heavy-duty needs in oil, fuel, water, and air piping scenarios, with a firm 73A hardness and a high-pressure rating up to 50 psi. It can handle demanding environments where chemical resistance is required.
Buying Guide: Key Purchase Considerations
- Material and strength: For structural or load-bearing uses, prioritize DOM steel or hot-rolled carbon steel with appropriate wall thickness. Square tubes offer stiffness in multiple planes, while round tubes provide high torsional strength for roll cages and frames.
- Pressure and temperature: Plastic tubing varies widely in pressure tolerance and temperature range. Check working pressure and operating temperature to match the intended fluid and ambient conditions. For high-temperature or aggressive fluids, steel tubes may be required.
- Flexibility vs. rigidity: Clear vinyl and braided PVC hoses deliver flexibility and easy routing, ideal for low-pressure transfer. For rigid frameworks, reinforced steel tubes maintain shape under stress.
- External and interior finish: Smooth interiors reduce sediment buildup and aging. PVC tubes with braided reinforcement resist kinking and elongation. For industrial cleanliness, look for BPA-free and non-toxic materials when used with potable liquids.
- Fittings and compatibility: Ensure the tubing type matches existing clamps, barbs, or fittings. Some items include clamps or are designed to work with common hose fittings, simplifying installation.
- Durability and environment: If exposure to UV, chemicals, or abrasion is expected, choose materials with suitable resistance. Steel tubes withstand mechanical abuse but require welding or specialized fabrication skills, while plastics offer corrosion resistance and easier handling.
- Length and customization: Pre-cut lengths or standard stock sizes can reduce on-site fabrication time. Consider whether you need additional cutting, trimming, or fabrication services to fit your project.
These options provide a balance between strength, flexibility, and practical use across automotive, industrial, and DIY contexts. When selecting tubing, align the material specifications with the application’s mechanical requirements, transfer needs, and installation constraints to ensure long-term performance.
