Subject: Direction of Flow Through Unions, Etc.
In flexible steel hose / steel loops / unions
..... Is there a proper or recommended direction of flow ..... If so
Unions, swivel joints, etc., do not have a preferred
direction of flow. The common practice of using male to male or female
to female union connecting subs gives certain confirmation.
If lines run vertical, best practice always has the
male union half turned down so that the nut will hang in place on the
male half with the union disconnected.
To properly understand Male and Female terms as used
to identify union halves, See:
How to Identify Male and Female Union Halves.
