36-inch brass round tube with mill finish

K & S Precision Metals

K & S Precision Metals 9225 260 Brass Round Tube 3/4 in OD 36 in Length

SKU CH-1SDA-XC1WB

260 brass round tube with a 3/4 in outside diameter, 0.692 in inside diameter, 0.029 in wall thickness and 36 in length for automotive, HVAC and plumbing use

  • 260 brass alloy resists corrosion in plumbing systems
  • 029 in wall thickness balances strength with easy bending
  • 3/4 in outside diameter fits standard compression fittings
  • 36 in length provides two ready-to-use pieces
  • ASTM B135 standard ensures consistent material quality

Brass Round Tube for Fluid Lines

This 260 brass round tube measures 36 in overall length with a 3/4 in outside diameter and a .029 in wall thickness. The inside diameter is .692 in, providing a consistent bore for fluid transfer. It meets ASTM B135 standards and is supplied in a package quantity of 2. The mill finish suits automotive, HVAC and plumbing installations.

Mill-Finish 260 Brass Upgrade

The alloy 260 composition replaces softer copper or lower-grade brass where dezincification resistance and machinability are required. The jump is worth it when a mill-finish tube must withstand vibration and moderate pressure without work-hardening cracks. The ASTM B135 certification confirms dimensional tolerances for repeatable fitting engagement.

Two-Piece Pack for Medium Runs

Each 36 in length gives 3 ft of straight run; two pieces yield 6 ft total for medium-length plumbing or HVAC circuits. The .029 in wall handles typical residential water and refrigerant pressures but runs out in high-pressure hydraulic or compressed-air systems. The fixed 3/4 in OD limits use to fittings sized for that diameter.

Questions about this item

What clearance does the 0.029 in wall thickness leave for a 3/4 in OD fitting?

The 0.029 in wall gives a 0.692 in inside diameter, so a 3/4 in OD fitting will not pass through; choose a fitting sized for the 0.692 in ID instead.

How do I cut the 36 in tube without crushing the 0.029 in wall?

Use a rotary tubing cutter designed for soft brass; tighten the wheel gradually over several rotations to avoid collapsing the thin wall.

Will the mill-finish 260 brass develop leaks that require replacement?

Mill-finish 260 brass resists corrosion in typical automotive, HVAC and plumbing fluids; inspect joints periodically and re-flare or re-solder only if a leak appears.
