Whether you're a machinist chasing a tight-tolerance sleeve, a plumber routing a custom line, or a maker building a decorative railing, finding a hollow brass round tube in exactly the right outer diameter and wall thickness is rarely straightforward. Generic hardware stores stock only a handful of sizes, leaving you to compromise on fit or waste time sourcing from multiple suppliers. This H59 brass hollow round tube solves that problem with a wide selection of metric sizes in a single, ready-to-ship listing.
Each piece is a single 500mm (≈19.7") length of H59 brass hollow round tube. Outer diameters span 13mm (≈1/2") through 40mm (≈1-9/16"), and wall thicknesses range from 2.5mm to 12.5mm depending on the OD selected — giving you a broad range of inner bore sizes to match your application. H59 brass (approximately 57–60% copper) offers good machinability, a warm golden appearance, and solid resistance to general corrosion.
Typical use cases include custom plumbing and fluid-transfer lines where a metric brass hollow pipe is required, decorative furniture legs and handrail inserts for interior design projects, precision sleeve bearings and spacers in light engineering and hobby CNC builds, and craft or jewelry applications where a thick-wall brass tube provides structural rigidity alongside visual appeal.

Measure the bore (inner hole) you need to fill or fit around, then add twice the wall thickness to get the outer diameter. For example, if you need a 16mm inner diameter with a 3mm wall, select the 22mm OD × 3mm variant. In imperial terms, 25mm OD is approximately 1 inch. When in doubt, size up — it is easier to reduce an outer diameter than to enlarge it.
H59 is a Chinese standard leaded brass alloy (roughly equivalent to C36000 free-cutting brass) with a copper content of approximately 57–60%. It generally offers good machinability and moderate tensile strength, typically in the range of 380–450 MPa, making it suitable for light structural, decorative, and fluid-handling applications.
Brass is naturally corrosion-resistant and performs well in most indoor and sheltered outdoor environments. For prolonged direct exposure to rain, salt air, or standing water, applying a clear lacquer or wax coating is generally recommended to prevent tarnishing and dezincification over time.
These tubes are metric-dimensioned (OD in millimeters). Compatibility with compression fittings depends on the fitting standard — metric compression fittings will typically match directly. For imperial plumbing fittings (e.g., 1/2" BSP or NPT), please verify the OD against the fitting's tube acceptance size before ordering, as nominal pipe sizes do not always equal the actual OD.
Yes. H59 brass machines and cuts cleanly with standard metal-cutting tools (hacksaw, pipe cutter, or milling cutter). It solders and brazes readily with common flux and silver solder. Bending is possible with a tube bender; thinner-wall variants (e.g., 3mm wall) are generally more bend-friendly than thick-wall ones. Annealing before bending reduces the risk of cracking.
Divide the millimeter value by 25.4 to get inches. Common conversions from this range:
For purely decorative or lightweight craft applications, thinner walls (2.5–4mm) are generally sufficient and easier to work with. For load-bearing, structural, or pressure-carrying applications, thicker walls (6mm and above) are typically recommended. When in doubt, consult an engineer for safety-critical uses.
