Does this item come in a set of two or when purchasing a single unit? Thanks

A  Answered on 8/23/2016 by InyoPools Product Specialist Alan M.

The unions come as pictured as a two piece set with the o-rings. Please note that these are the connectors only and do not include the opposite threaded side that the connector is fitted to.
