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 suck a set up.
This Taprite regulator has a warranty that is double what the manufacture provides. (Click here to view warranty). I 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.
