K65
QA Certificate
Certificate type
Brazed pipe fittings.
High pressure air-conditioning, high pressure refrigeration. CO2
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 transcritical applications as the K65 alloy provides a mechanical strength high enough to withstand the pressure ratings required. PED 2014/68/EU
Features and benefits:
- UL recognised component with a maximum operating pressure of 130 bar.
- Easy to identify - even after installation due to clear marking.
- Lightweight.
- Corrosion resistant material
