Ascaso W..517 1/4" Threaded Bleeder / Vacuum Breaker Valve
This bleeder/vacuum breaker valve is used to deplete the vacuum pressure in the espresso machine’s boiler once it cools down. This item is confirmed to fit the Fiorenzato Bricoletta and Volante 1 group espresso machines.
This bleeder valve for an espresso machine has 2 o-rings where the seal is made – this is helpful in preventing failure from limescale build up. In addition, the weight on the plunger is heavier than that of the standard vacuum breaker/bleeder valves found on most espresso machines.
The thread is 1/4 inches, and the metal portion is made of brass. The thread should be given an application of 1-2 rounds of thread seal tape. Make sure to change this part when the unit has been completely cooled!
