Level regulator body nut in the drinker (TAV11)

Nut for the regulator body in the drinker - TAV11 screwed in. Used in most types of bell drinkers offered on the market.
The task of the drinker nut is to block the body of the TAV10 regulator against its involuntary unscrewing from the thread of the jug from the drinker. After setting the regulator body at the right level, tighten the nut quite tightly until we stiffen the body and it will not be possible to twist it. Then we can be sure that the bell drinker is properly protected against valve twisting. The cap for securing the drinker is made of hard plastic. The goods are sold by pieces.
