Set Pressure: ~ 0,25 bar

The new Sfiatech offers the functionality of the standard breather plug Nostrali and adds some new feautures: zinc plated cap with different diagram for different functionalities; the diameter of the cap is lesser than the hex key useful to be assembled with any kind of spanner; the cap so designed is a natural labyrinth that limits oil leakage; thread profile is inspired by the rule DIN 908; new FKM inner seal instead of NBR to withstand higher oil temperature, avoiding a stick effect. Upon request the inner seal could be teflon-coated wihtstand higher oil temperature.
