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.

Standards
DIN 8964, which stipulates a maximum leak rate for refrigeration plant of < 6.4 × 10-6 mbar l/s at a di…erential 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
