ABSTRACT:
An improved apparatus for securing an externally threaded line tap valve to the exterior of a penetrable tubing line such as that found in a closed refrigeration system. The apparatus is adapted to secure a line tap valve to a line having any of a plurality of outside diameters. The apparatus includes a body member having a threaded passage extending therethrough and a substantially square lateral cross-section. A first cylindrical outer surface is formed adjacent one end face of the body member and a second cylindrical outer surface is formed intermediate the first cylindrical outer surface and the opposite end face of the body member. The apparatus also includes a bifurcated spring clip member having an upwardly facing V-shaped bottom portion and inwardly facing lips formed on the two upwardly extending parallel leg portions having arcuately shaped vertical notches formed respectively therein for engaging and retaining either of the cylindrical outer surfaces of the body member therein when the apparatus is assembled. A spacer member is included for interposition between the clip member and the tubing to which the apparatus is to be secured when tubing of smaller diameter is involved. The threaded line tap valve is threadedly received within the threaded passage through the body member when the line tap valve penetrates the tubing.
