A union assembly useful in a fluid flowstream includes a body portion, a pressure indicating device and a removable cover. The body portion includes a bore, an access opening and pressure indicating device cavity in fluid communication, and a first plurality of threads disposed around the access opening. The removable cover includes a passageway and a second plurality of threads disposed around the passageway. Engagement of the first and second pluralities of threads will secure the removable cover to the body portion for use of the union assembly without any additional mechanism connecting the removable cover with the body portion. When the union assembly is assembled, a cut-out portion on the removable cover is disposed at least partially around the pressure indicating device, whereby the pressure indicating device must be disengaged from the body portion before the removable cover may be disconnected.
