These sampling valves can stay attached to your fermenter and provide easy removal of samples for gravity readings and tasting. If the beverage in the fermenter is cold (e.g. when crashing) or not carbonated there is little foam when poured through this valve, but if the beverage is not cold and carbonated, there will be more foam and the pigtail attachment (purchased separately) is recommended to help reduce foaming.
This valve comes with an EPDM gasket which is rated up to 100C/212F. Connects to 1.5" sanitary tri clamp ferrules.
