The stainless steel screen and elbow slips right in the end of the kegs dip tube giving you a 4 inch long and ½ inch diameter bazooka style filter. The extra surface on the filter screen makes it great for dry hopping and filtering out other solid flavoring ingredients you have added to your beverage.
Note: Can be used with all strait dip tube style kegs. (The dip tube may flex slightly toward the center of the keg bottom once the post is tightened down. See image.) Other dip tube designs may need to be altered (slightly bent or cut) for best results.
