Rubber carboy blow off hood w/white caps (3, 5, 6, 6.5 gallon smooth neck)
5' 3/8 inch
Sterilized air filter
Description
Simply blow into the sterile filter, which slightly pressurizes the carboy, causing beer to flow out. Attach the sterile Siphon starter assembly by firmly pushing the orange or yellow carboy hood over the mouth of the carboy. Slide the stainless racking cane to the desired depth, just about the sediment level and blow into the white, sanitary air filter for 2-3 seconds. Blowing through the filter forces beer out through the racking cane, starting the Siphon. There is no need to worry about contamination from your mouth, as the sanitary filter removes 99.98 percent of airborne bacteria. Sterile Siphon includes: 26 inch stainless racking cane red sediment reduction tip orange carboy hood for 5 gallon Carboy5' 3/8 inch ID vinyl tubing stainless hose clamp sterile air filter about the white sterile filter: there are two sides to the filter - an "in" and an "out". the direction you use doesn't matter, however, you want to take note of which way you first push air through it and always keep it that way. There is an arrow on the edge of the filter housing that we use to keep the air flow going one direction when using it. The filter should never get wet, so don't try and sanitize it by dunking it in sanitizer. If you want to clean the outside of it, use Alpet D2. To store the filter, use a little tinfoil on the "in" of the filter and store in a zip-lock bag.5.

Kegco 5.5 Gallon Wide Mouth Glass Carboy Fermenter Homebrew Beer & Wine Making
Feature
WIDE MOUTH MAKES CLEANING EASIER THAN EVER: The glass jar is less likely to get scratched up than a plastic carboy or bucket, so these jars are already easy to clean, but the wide mouth makes it even more convenient than a normal carboy. Stick your whole arm inside of the vessel to reach all of the surface area with a cleaning cloth, ensuring bacteria has no place to hide.INSTALL YOUR OWN AIR LOCK: When using this jar as a fermenter, gas will be released from your brew. If the vessel were sealed airtight, the added gas could cause the jar to explode if not vented properly, but if there is not a good seal, your brew could become oxidized. The removable cap on the lid allows you to install a drilled #3 rubber stopper with your own air lock so the gas can vent without allowing in oxygen.
BUILT-IN AIR LOCK: The lid has a recessed area with a removable cap that can be replaced with a breather cap to use as an air lock. The breather cap allows gas to escape from the container during fermentation and having it in a recessed area allows you to fill it with sanitizer so that the released gas can bubble out, but harmful oxygen and impurities cannot get in and contaminate your brew.
ADJUSTABLE DIAL TO SET BREW DATE: The lid features an adjustable dial that allows you to set the date that you begin fermentation, so if you have multiple batches going at the same time in different jars, it's easy to keep track of when each one started! Simply turn the inner dial to the month and the outer dial to the day. No more sticking a piece of tape on the side with a date scribbled on it!
DURABLE STRAPS MAKE CARRYING EASY: If you've ever tried picking up a slippery jar that's filled with a few gallons of liquid, you'll appreciate the convenience and safety of having a strong woven nylon strap to lift and carry the jar from place to place. The straps fit snugly around the jar and criss-cross the bottom to evenly support the weight, but can be quickly slid off the jar for cleaning.
