Wieland K65 tubes have been designed for CO₂applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO₂.

At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP / C12200). Wieland K65 tubes are offered from stock in three pressure ranges, 80 bar, 120 bar, and 130 bar and in dimensions ranging from 3/8” up to 2-5/8”.
