3/8" Stem to 3/8" Barb John Guest (adapter for Grainfather pressure transfer) PI251212S-R

This will push into silicon line from a grainfather pressure transfer kit so beer can be transferred to a corny keg without exposure to oxygen / air.

You will need to add a 3/8" to 3/8" push fit and then some 3/8" line and the disconnect and fitting to get the beer actually into the keg.

If you want help with pressure transfers give us a shout.
