>B< K65 brazed fittings

K65 brazed fittings, developed in conjunction with Wieland, enable the simple, safe and economical installation of high pressure refrigeration applications up to 130 bar. The range is particularly suited for use with CO2 (R-744) in trans-critical applications as the K65 alloy provides a mechanical strength high enough to withstand the pressure ratings required.
