Three embodiments of a self-retaining fluid system component insert for a smooth bore of predetermined diameter. The insert comprises a helical coil spring with one end thereof connected to the component and having, in its relaxed state an outer diameter slightly greater than the bore diameter to frictionally lock the insert within the bore. The insert has a threaded connector for receiving an elongated tool for mounting the insert by rotating the insert in one angular direction thereof for contracting the coil by its frictional engagement with the smooth wall of the bore.

An insert for mounting a miniaturized fluid system component within a smooth bore of predetermined diameter comprising a fluid system component and means for retaining said component in said bore sufficient to provide self-retaining against a force having a magnitude which is at least equal to the weight of the insert, including a helical coil spring having a plurality of turns and a relaxed state with an outer diameter slightly greater than said predetermined diameter to provide frictional resistance between the coil spring and the bore to frictionally lock the insert within the bore, the ends of the coil spring being relatively rotatable to contract the coil spring slightly by rotation of a first end thereof in one angular direction relative to the other end thereof as a result of said frictional resistance between the coil spring and the bore, and means for rotating the coil spring in said one angular direction comprising a connector generally coaxial with the coil spring and connected to said first end thereof and adapted to be coupled to a tool by rotation of the tool in said one angular direction and for installing the insert by rotation of said coil spring with the tool in said one angular direction.
