Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
In an injection molded distribution fitting having a plurality of outlet port means for forming a compression joint for receiving a distribution tube, each of said port means being adapted to be connected to a distribution line the improvement which comprises: said fitting having a spherical peripheral wall, said spherical wall having both a spherical interior and a spherical exterior, said port means being located in said wall, said wall having a uniform thickness adjacent to each of said port means. each of said port means is defined by a circular hole located in said peripheral wall, each such hole being located so that an imaginary line extending perpendicular to its center will intersect the center of said peripheral wall and each of said port means being shaped so as to include a beveled exterior surface leading to an edge, said edge surrounding and defining said circular hole, a tube located within each of said ports so as to be held therein under compression.
