uxcell Brass Tube Set — 2mm to 7mm OD
The uxcell kit provides a range of thin-wall brass tubes in multiple outer diameters (2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm) with a consistent 0.5 mm wall and a 200 mm length. Made from brass for strength, weldability, and corrosion resistance, these tubes are well-suited for DIY projects, small frames, models, and crafts. The set is ideal when you need quick, varied sizes without buying individual tubes. They cut and weld with standard tools used in hobbies or home workshops.
Eorbow Brass Round Tube Set — 9 Sizes
This 18-pack includes 9 sizes (2 mm to 9 mm OD) with a 0.5 mm wall and 300 mm length, offering versatility for model making, crafts, and lightweight structural projects. The tubes are manufactured in H65 brass, combining high strength with ductility. They’re relatively easy to cut or punch and weld, making them a practical choice for hobbyists and model builders who require a broad size range in one purchase.
K&S 8129 Round Brass Tube — 3/16″ OD
Manufactured from Alloy 260/272, this 3/16″ OD brass tube is seamless with a mill finish and is compliant with REACH/ROHS standards. It is designed for high-quality performance in plumbing, HVAC, and modeling projects, offering reliable strength and smooth interior surfaces. The tube is a strong option for users who prioritize durability and consistency in small-scale installations and crafts.
K&S Precision Metals Telescopic Tube Assortment
This assortment covers multiple diameters from 1/16″ to 13/32″ OD, all at 12″ length with 0.014″ wall. It serves a wide range of DIY projects, model making, and spacers. Made in the USA, the tubes are designed for easy cutting, shaping, and soldering, making them a versatile choice for hobbyists who need various sizes in one kit.
M METERXITY 1-Pack Brass Round Tube
This 300 mm long tube features 5 mm OD and 1 mm wall thickness in H62 brass. It’s positioned for construction, machining, and DIY crafts, with good corrosion resistance and mechanical properties. The tube is suitable for wind chimes, architectural models, or small structural elements where a precise 5 mm bore is needed and easy cutting is important.
K&S Precision Metals Round Brass Tube 8139
Featuring 1/2″ OD and 0.014″ wall thickness, this 12″ long tube is also made in the USA. It’s designed for HVAC, plumbing, and modeling applications that require robust brass with a smooth interior. The sealed, uniform stock supports precise fabrication and durable finishes in both indoor and outdoor settings.
Buying Guide: Key Purchase Considerations
When choosing thin-wall brass tubing, consider the following aspects to ensure you select the best option for your project:
- Size range: If you work on multiple models or projects, a set with many OD options reduces the need to acquire individual tubes.
- Wall thickness: Thinner walls save weight and material but may limit structural load; ensure the thickness matches your strength requirements.
- Length and cutting: Longer tubes provide flexibility; check ease of cutting, punching, and soldering with your equipment.
- Alloy composition: Brass alloys (e.g., 260/272, H62, H65) determine strength, ductility, and corrosion resistance. Choose based on exposure (indoor/outdoor) and required workability.
- Surface finish: Mill finish and interior smoothness affect soldering and flow of fluids or air in small systems.
- Manufacturing origin: USA-made tubes often assure consistent standards and easier compliance with local regulations.
- Corrosion and compatibility: For HVAC or water-related uses, ensure compatibility with the fluids and environments involved.
- Storage and handling: For multi-size sets, keep tubes sealed and protected from oxidation when not in use to extend lifespan.
Across these options, users can balance cost, variety, and quality. For hobbyists, a mixed-size set offers convenience; for professionals, verified alloys and precise tolerances support reliability in functional assemblies. Consider your project requirements—weight, strength, and ease of fabrication—when deciding which tubing to buy.
