The PRO-Fit Precision Flaring Kit is a pipe flaring tool for copper and aluminum tubing used in air conditioning and refrigeration work. It helps prevent potential sidewall splits and leaks associated with slow traditional flaring tools when forming 45-degree field-applied refrigeration tubing flare connections.

The easybend kit consists of four color-coded, industrial-grade, solid, polyethylene mandrel diameters. It is 13 feet long and fits quickly, but snugly, into soft copper lineset tubing sizes of ¼-, 3/8-, ½-, and 5/8-inch.

Uniweld’s UEK1 Hydraulic Expander Kit for swaging copper tubing will save you time and money by eliminating copper fittings and solder joints. 

The International Copper Association (ICA) and Optimized Thermal Systems Inc. (OTS) announced that newly developed MicroGroove™ small-diameter copper tube correlations will be implemented in CoilDesigner® software, a proprietary heat exchanger simulation and design optimization tool.

Smaller-diameter copper tubes strengthened with low percentages of alloying elements can withstand the higher pressures of the new refrigerants such as CO2 (R-744), according to the International Copper Association.

Concerns related to soldering copper tube and the new no-lead copper alloys led the Copper Development Association (CDA) to conduct laboratory research and testing out in the field. The CDA found that, in many cases, those working with the new no-lead copper alloys were using the incorrect soldering procedure.
