Brass Round Tube for Automotive and Plumbing

Zoro Select 8144 260 brass round tube measures 12 in long with a 21/32 in outside diameter and a 0.628 in inside diameter. The 0.014 in wall thickness provides structural rigidity while keeping weight low. Mill-finished 260 grade brass meets ASTM B135 and ASTM B587 standards. It operates reliably from 0 to 1690 degrees F.

Suits fluid lines in automotive HVAC

Builders who need a corrosion-resistant tube for water, refrigerant or fuel lines will find this alloy and size appropriate. The inch-based dimensions match legacy fittings common in maintenance work. Projects that require metric sizing, thicker walls for high-pressure hydraulic circuits or a different alloy such as stainless steel should look elsewhere.

21/32 in outside diameter fits legacy inch fittings

The 21/32 in OD is the critical dimension that determines compatibility with existing compression fittings and tubing tools. Verify this exact size against your system specifications before ordering. If your application calls for a different outside diameter or a heavier wall, this tube will not suit the installation.

Questions about this item

How much heat can the 260 brass tube with a .014 in wall handle before it weakens?

It is rated for a maximum temperature of 1,690 °F and a minimum of 0 °F, so it will not soften under normal automotive or HVAC heat loads.

What fittings or tools do I need to connect this 21/32 in OD tube to my existing system?

You will need compression, flare or solder fittings sized for a 21/32 in outside diameter and a .628 in inside diameter, plus a tubing cutter and deburring tool.

Will this 12 in length of 260 brass tube thread into the older steel pipe I already have?

No, the tube has a plain mill finish with no threads; you must use a brass-to-steel compression adapter or sweat joint to join it to threaded pipe.
