You will Benefit when you use SKY Copper fittings
because they are:
• Designed, Manufactured and Tested to exceed the Australian Standard AS1571.
• Manufactured to stringent standards in an ISO9001 accredited facility.
• Passed through a rigorously controlled QA system including batch verification
burst testing.
• Designed and manufactured to remove stress and fatigue focus points.
• All fittings less than 1 inch connection size are rated for refrigerant R-410A and
CO2. (SWP 5200 kpa)
• R-410A rated fittings are marked accordingly on the fitting for your safety.
R-410A
• SKY’s rating is based on the AIRAH accepted, standard safe working pressure for
Refrigerant R-410A 4,800 kpa @ 65°C.
R-744 (CO2)
• SKY’s rating is based on the AIRAH accepted, standard safe working pressure for
Subcritical Refrigerant R-744 as 5,200 kpa for standard fittings.
• Mueller’s rating is based on a combination of UL and EN378-2, 60 bar and 130
bar.
Installation:
• SKY copper fittings should be installed in accordance with the methodology
recommended in AS HB40 by suitably qualified trade’s people.
• 15% silver solder is recommended when brazing fittings into systems intended for
R-410A or other high pressure applications.
• Pipe work should be designed and implemented in a way that mechanical and
thermal stress is avoided.
• Burst testing of SKY copper fittings is done after the joints are braised to replicate
as close as possible their application in the field. However, as copper can work
harden and these fittings can be subject to unique dynamics created in the
working environment, such as vibration, temperature, pressure and pulsation,
end-users should satisfy themselves of the fitting suitability for the application.
Copper in short:
• Due to their superior design, manufacture, QA and labelling, SKY copper fittings
when installed properly will improve the outcome of your installation, and reduce
the risk of premature failure and subsequent refrigerant leakage.
