SANITARY FITTING FOR FLUID HANDLING EQUIPMENT

摘要

A sanitary fitting for biopharmaceutical equipment includes an elongate tubular insert having a main tubular section, which is cylindrical and terminates at an annular flange or annulus which seats at a bottom of a socket in an equipment housing. The bottom face of the annulus includes a groove, which receives a gasket that is compressed between the annulus and bottom face of the socket to prevent entry of fluids into this space. A threaded section of the socket is spaced outwardly of the smooth surfaced fitting so as to receive a threaded nut within such space. A threaded nut is slid down the fitting and engaged with the socket threads wherein the nut drives the socket into and retains the fitting tightly within the socket.

1. A threaded sanitary fitting for an equipment housing, comprising:
a non-threaded tubular insert, which is insertable axially into a housing socket of an equipment housing, said insert having a main tubular section, which extends axially, is cylindrical and terminates at an end portion, said end portion including an annular flange which projects radially outwardly from said tubular section so as to seat at a bottom of said housing socket when installed, said flange including a gasket positioned for contact with an opposing surface of said housing socket when installed; and a nut which is slidable downwardly over said insert to abut downwardly against a top face of said flange, said nut including a threaded exterior surface engageable with an opposing threaded surface of a housing socket to drive said inert into the housing socket and retain said insert tightly therein.
