Abstract
A flare-tube assembly is provided that includes a tube having a flare at a forward end thereof which angles outwardly and rearwardly and is generally S-shaped in cross-section. The flare-tube assembly also includes an inverted flare fitting which has external threads, an opening extending therethrough, and a shoulder encircling the opening at a forward end of the fitting. The shoulder has a recessed portion near an outer diameter of the shoulder which is inwardly arcuate in cross-section. The tube extends through the opening with the shoulder of the fitting facing a rear side of the flare. During installation, the fitting is torqued such that the shoulder of the fitting first engages and compresses an outer portion of the flare to form a seal at the outer portion. Upon further torquing, the shoulder of the fitting engages the entire surface of the flare to compress the entire flare.
