Copper tube used for air conditioning and refrigeration applications in the field (sometimes called "refer" or "acr" tube) is an almost pure copper material meeting the requirements of astm b 280 - standard specification for seamless copper tube for air conditioning and refrigeration field service. It is manufactured from copper alloy c12200 having a chemical composition of a minimum of 99.9% copper (cu) and silver (ag) combined and a maximum allowable range of phosphorous (p) of 0.015 % - 0.040 %.
B 280 tube is produced in straight lengths or coils in tempers h58 or o60 respectively, although annealed straight
Air conditioning and refrigeration tube (astm b 280) either coiled or straight length is further required to be cleaned and capped prior to shipping.
Pancake coil wrapped with plastic bag both end capped then put into carton box for several pieces

Seamless brass tube Seamless brass tube is manufactured to the requirements of astm b 135 - standard specification for seamless brass tube and may be either round, square, or rectangular and is suitable for general engineering applications. It may be manufactured from any one of the following alloys: c22000, c23000, c26000, c27000, c27200, c27400, c28000, c33000, c33200, c37000, or c44300 and these alloys contain copper (cu) concentrations of between 60% and 90% with various percentages of zinc (zn), lead (pb), and tin (sn) permitted, depending on the alloy. Tubes meeting this standard may be furnished in any of several tempers ranging from light drawn to light annealed. It is the responsibility of the purchaser, when ordering to provide the requirements for alloy (uns#), temper, dimensions (diameter and wall thickness, or distance between parallel surfaces), form (straight lengths or coils), and total length or number of pieces of any particular size.
