Off-the-shelf hardware store stock rarely covers the sub-10mm range, and ordering from overseas means long waits and inconsistent quality. These brass round tubes are stocked in 18 OD sizes from 1mm to 12mm, all with a consistent 0.3mm wall thickness, so hobbyists, makers, and small-shop fabricators can get the exact fit they need without compromise.\u003c\/p\u003e\n    \u003cp\u003eEach listing covers a single tube, 500mm (≈19.7\") long, made from brass alloy with a smooth, bright finish. The outer diameter (OD) ranges from 1mm (≈0.039\") up to 12mm (≈0.472\"), and the wall thickness is a uniform 0.3mm across all sizes — giving an inner diameter (ID) that is consistently 0.6mm less than the OD (e.g., 6mm OD = 5.4mm ID). All sizes are available in the 500mm fixed length; cut to your required dimension on-site.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include telescoping tube assemblies for RC aircraft and car chassis, small-bore tubing for model steam boilers and plumbing mockups, jewelry findings and tube rivets for metalsmithing, and structural spacers or standoffs in precision instrument housings. The consistent wall dimension across the full size range makes these tubes well-suited for nested or telescoping brass tube applications where adjacent sizes need to slide together.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003eℹ️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e These are plain, unthreaded hollow brass tubes.
