ABSTRACT:
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.
