Introduction
Standard Fitting
Heldon’s standard copper fittings are substantially thicker on average than other fittings available on the market today as
they are manufactured to exceed B 16.22-1989. As a consequence, they also have a higher pressure rating. Heldon’s copper
fittings are available in sizes up to 4 1/8”
R400 Series fittings
Heldon’s R400 Series fittings are packed or stamped R400 and are suitable for R410A, R407C and many other 400 series
refrigerants, with Fitting Safe Working Presures (F SWP) of approximately 5,000kPa at ambient, in sizes currently up to 1
5/8”. Heldon ‘Standard’ fittings up to 2 5/8” are also available for the Low Pressure side of R410A systems (2,500kPa).
Special Fittings
Can be designed and made to customer requirements in many sizes.
Heldon’s coper fittings are suitable for use with the American ‘Copper Tubes for Air-conditioning and Refrigeration Field
Service – ASTM B280’ and ‘Australian and New Zealand standard AS/NZS 1571.’
Heldon Copper fittings are still the best choice, especially as the industry moves to higher pressure refrigerants.
