General information
Features
SFP-AF caps (registered design) are made with a special internal geometry which stops the leakage of the fluid to the outside.
The hexagon on the threaded fitting makes it possible to apply, using a wrench, a greater tightening torque on the cap, ensuring better compression of the gasket.
Technical data
Air flow rate for the different executions of breather caps can be obtained from the diagram on the basis of the difference of air pressure inside and outside the reservoir.
