Abstract
Abstract In an assembly including; three individual components to be series connected in a fluid flow line, for example, a filter, a controller and a lubricator for pressurized air, each component is provided with bolt receiving holes in its front and rear surfaces. One component has four threaded holes on each of its front and rear surfaces while the other two components each have two threaded holes and two unthreaded bores therethrough, all circumferentially spaced around inlet and outlet ports in the surfaces.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
180 words
An assembly to be inserted into a fluid conduit comprising first, second and third components to be inserted in series into the conduit, each component having opposite external surfaces having a port defined therein to allow fluid flow therethrough, a clamping flange on each of two fluid conduit sections between which the components are to be inserted, and a pair of bolts for each flange, characterized in that said second component has four threaded bolt receiving holes on each of its opposite surfaces circumferentially spaced around the respective port in each surface, the centers of the holes defining a square, said first and third components each have a pair of bores therethrough opening in each of said opposite surfaces and a pair of threaded bolt receiving holes in each of said surfaces, the centers of the bores and holes on each surface defining a square with the bores being located at diagonally opposite corners, and the bolts project through the flange and through the bores in said first and third components to engage the threaded holes in sAid second component.
