K & S Precision Metals 9211 Brass Round Tubing 5/16 in OD 36 in Length

SKU CH-CPC8-5XTRK

A 260 brass round tube with a 5/16 in outside diameter, 0.254 in inside diameter, 0.029 in wall thickness and 36 in length for automotive, HVAC or plumbing use

  • 260 brass alloy resists corrosion in automotive and plumbing systems
  • 5/16 inch outside diameter fits standard compression fittings
  • 029 inch wall thickness balances strength with easy bending
  • 36 inch length provides ample stock for custom fabrication
  • ASTM B135 grade ensures consistent mechanical properties

Brass Round Tubing for Automotive and Plumbing

This 260 brass round tube measures 5/16 in outside diameter with a 0.029 in wall and 0.254 in inside diameter. The 36 in length arrives in a pack of five pieces finished to ASTM B135 standards. Mill finish surface suits machining, bending and soldering in fluid-handling projects.

Suited for Builders Needing Small-Diameter Brass

Mechanics, plumbers and hobbyists fabricating fuel, brake, hydraulic or refrigerant lines will find the dimensions convenient. Buyers who require larger bores, thicker walls or metric sizing should look at alternative tubing stock. The material is not rated for structural pressure vessels beyond the standard alloy limits.

Critical Spec Is 5/16 in OD With 0.029 in Wall

The outside diameter and wall thickness determine fit inside fittings and flow capacity for the intended system. Confirm these two figures against your design before ordering. The 36 in length and pack quantity are secondary considerations once the diameter match is verified.

Questions about this item

What fittings or tools do I need to connect the 5/16 in OD brass tube to my existing plumbing?

You will need 5/16 inch compression fittings or flare fittings rated for 260 brass, plus a tubing cutter and deburring tool to prepare the 36 inch length for a leak-free seal.

Can I join this 260 brass tube to older copper pipe without galvanic corrosion?

Use a dielectric union or brass-to-copper transition fitting; the 0.029 in wall and 0.254 in ID match standard sizing so the joint stays mechanically sound.

How can I verify the tube meets the ASTM B135 standard after I receive it?

Check the mill finish for uniform colour, measure the OD at 5/16 in and wall at 0.029 in with a caliper, and confirm the 36 inch length across all five pieces.
