Data Sheet
Adaptor
Type FSA
Easy and fast component replacement
With the are / solder adaptor, type FSA, are
connections can be easily and reliably changed
to solder connections.
The adaptor provides a method of joining that
preserves the advantages of are connections,
i.e. easy and fast component replacement. At
the same time, the are / solder adaptor also
provides the advantage of soldered joints, i.e. a
high degree of tightness that prevents leakage.
The adaptor contains no soft gaskets or O-rings
which age and loose their sealing properties.
Instead, it contains a copper seal which
protects the are collar against wear and
fatigue. This copper seal ensures a thightness
similar to that of soldered joints.
The copper seal must be changed each time
the adaptor is dismantled for servicing are
components.
Frost grooves in the nut mean that the
adaptors are suitable for wet environment,
where the temperature is below the water
freezing point. The nut cannot be loosened by
encapsulated ice formation.
Features
• The are / solder adaptor, type FSA, is for use
where servicing or some other factor makes a
“genuine” solder connection impractical.
• The adaptor can be used with advantage for
components with are connections on:
1.
Pressure controls
2.
Filter driers
3.
Sight glasses, etc.

Product specication
Standards
DIN 8964, which stipulates a maximum leak rate for refrigeration plant of < 6.4 × 10-6 mbar l/s at a dierential
pressure of 10 bar He.
The Dutch refrigeration standard (9.12.94/IBP 07d 94007, part 2.2.8.2.): In variation to regulation 2.2.8.1 anged
joints, compression joints, quick-couplings, at or conical packing or trapped O-rings will be permitted, but only if
the packing or O-ring provide the seal and are replaced if the joint is disconnected and then remade.
Technical data
Refrigerants: only approved for A1 and A2L refrigerants
Max. working pressure: PS/MWP = 46 bar
Leak rate: Max. 1 g / year
