FMC Hammer or Wing Unions

Hammer Unions, also called Wing Unions, are quick makeup and break-out pipe and fitting connectors that consist of a male sub with a spherical
sealing surface, a female sub with external acme threads, and a wing nut with internal acme threads to hold the components together.
A safety bulletin describing the general categories of hammer union connection and component mismatches is available from FMC.
