3/8" Anti-Vacuum Valve - Stainless Steel
The larger 3/8" anti-vacuum valve used on Rancilio (and Promac/Laranzato) boilers, letting air escape as the boiler heats and preventing a vacuum from forming as it cools. Not to be confused with the more common 1/4" valve (W_517), this one has a male thread measuring 5/8" across the outside diameter.
COMPATIBILITY
- Fits: Rancilio, Promac, and Laranzato boilers using the 3/8" (5/8" O.D.) anti-vacuum valve, not the smaller 1/4" style
- Works with: the W_154 gasket, the best sealing option for this valve
INSTALLATION
Straightforward DIY boiler fitting swap for anyone comfortable draining and accessing the boiler.
PRO TIPS
- Measure the male thread O.D. before ordering, at 5/8" this is noticeably larger than the common 1/4" valve, and installing the wrong size will never seal properly.
