K&S 8129 Round Brass Tube — 12″ Length
The K&S 8129 Round Brass Tube is a 12-inch seamless tube made from a 260/272 alloy and finished to a mill standard. It is described as 1/2-3/4 hard and is suitable for applications requiring good rigidity and machinability. The tube adheres to ASTM B135, and it is REACH/ROHS compliant for safer handling in consumer and professional projects.
Tynulox H62 3/16″ Brass Tube — 300mm
These 300mm tubes use H62 brass with a wall thickness of 0.02″ (5/64″). Sold in a 2-pack, they provide excellent heat transfer and electrical conductivity, with good corrosion resistance under typical operating conditions. The 3/16″ outer diameter yields a compact, sturdy profile suitable for hobby machining and small structural components.
YTKavq 3/16″OD Brass Tubing — 12″ Length
YTKavq’s 3/16″ OD tubes feature a 0.02″ thick wall and measure 12″ in length, supplied as a 2-pack. These tubes are marketed for knife making, crafts, and electrical projects, highlighting ease of fabrication and strong conductivity, with a polished finish suitable for visible assemblies.
K&S 1147 Round Brass Tube — 36″
This K&S tube offers a longer 36″ length, with a 0.014″ wall and 3/16″ outer diameter. It is designed for DIY crafts, plumbing, HVAC, or modeling projects that benefit from a longer, continuous run of brass tubing, while maintaining easy machinability and consistent wall thickness.
K&S 8153 Square Brass Tube — 12″
The K&S 8153 is a 12″ square brass tube with a 0.014″ wall thickness. Made from seamless alloy 260/272, it provides rigidity for framing, crafts, and model work. The square cross-section makes it easy to align with other flat components and reduces rotation in assemblies.
Buying Guide: Key Considerations For 3/16 Brass Tubing
Selecting the right 3/16 brass tubing depends on several factors, including cross-section, wall thickness, length, and alloy composition. Consider the following perspectives to ensure a fit for your project:
- Cross-section: Round tubes are ideal for tubular frames and conduits, while square tubes offer flat surfaces for joints and fasteners. Choose based on required geometry and machining compatibility.
- Wall thickness: Thicker walls (e.g., 0.02″) increase strength and rigidity but reduce internal bore size. For delicate models, a thinner wall (0.014″–0.016″) balances strength and weight.
- Alloy and finish: Brass alloys like 260/272 are common for versatility and machinability. Mill finishes are suitable for visible components, while polished or treated finishes help corrosion resistance in certain environments.
- Length options: Standard lengths (12″ and 36″) suit modular builds, while longer or two-pack options can reduce joints and waste. Ensure compatibility with your cutting, drilling, and soldering processes.
- Conductivity and corrosion: Brass conducts heat and electricity well for DIY electronics and heating projects. Guard against corrosion in humid or aggressive environments by choosing appropriate corrosion-resistant variants.
- Fabrication methods: Brass tubes cut cleanly with hobby saws, drilled with standard bits, and soldered with common fluxes. For precise fits, consider tube end chamfering and deburring after cutting.
- Availability and sourcing: Multiple brands offer similar 3/16″ tubes. Compare wall thickness, length, and cross-section to ensure consistency across parts you plan to connect.
In summary, the best 3/16 brass tubing choices balance length, wall thickness, and cross-section to match the project need—from long runs in HVAC to compact, robust components for knife-making or models. Review the product specs and compatibility with your tools before purchasing.
