About the cross

A four-way cross fitting provides two perpendicular branch connections in a single fitting. Less common than tees; used in compact manifolds, sample stations, and instrument headers where four lines meet at one point.

Four outlets at 90°: two run ends and two opposed branch outlets
Equal cross: same bore on all four outlets
Reducing cross: branch outlets smaller than run; specify all four sizes
Single factory fitting replaces two tees and a spool piece
