# Types available on request with NPT thread (National Taper Pipe Thread - ANSI-ASME B1-20).
Material
Polyamide based (PA) technopolymer.
- Cap: semi-matte finish, black colour, with “fill” symbol.
- Threaded connector and external anti-splash semi-discs, black colour.
Packing rings
NBR synthetic rubber.
Standard executions
- SFX.: with splash guard, without air filter.
- SFX+F: with splash guard, 'tech-foam' air filter in polyurethane foam mesh (polyester base), air filtration 40 µ.
- SFX+P: with splash guard and external anti-splash semi-discs, without air filter.
- SFX+P+F: with splash guard and external anti-splash semi-discs and “tech-foam” air filter in polyurethane foam mesh (polyester base), air filtration 40 µ.
Maximum continuous working temperature
100°C.
Features and applications
The SFX. breather caps are made with a special internal geometry (Elesa patent) that prevents the leakage of fluids through a linear labyrinth (splash guard effect) and promotes condensation of the outgoing vapours.
The external snap-on anti-splash discs (execution+P) located at the mouth of the threaded fitting hole, are made up of fins offset from each other so as to constitute an additional labyrinth in the most critical cases of strong fluid projections.
Technical data
Air flow rate for each model can be determined from the graph here below by calculating the difference between the pressure inside and outside the reservoir.
Special executions on request
- Neutral cap without symbols.
- Cap in RAL 3000 red colour.
- Threaded fitting also with American conical gas threading NPT - ANSI-ASME B1-20 for the descriptions marked in the table with #.
