A Taprite Secondary 4 body regulator is a great way to provide different pressure to four separate kegs. This is much more flexible than a four way air distributor that would often be used with such a set up.
This Taprite regulator has a warranty that is double what the manufacture provides. (Click here to view warranty). It is also assembled in the USA and features UL ratings.
You just need to decide if you want a high-pressure version or low pressure version. The low-pressure is the most popular and connects to a primary regulator via a low-pressure hose providing about 40 PSI of pressure. The high-pressure version does not require a primary regulator but needs a special high pressure hose.
This regulator is part of Taprites premium 740 series, not the economy series that you will find on some sites. This is a commercial grade regulator!
