ABSTRACT:
An adjustable plumbing fitting is adapted to adjust a length of connection between supply and inlet pipes, and includes a sleeve member, a collar member, and a sealing member. The sleeve member includes an annular section sleeved on and threadedly engaged with the inlet pipe, and a protrusion extending radially from an outer surface of the annular section and abutting against the supply pipe. The collar member includes a tube section sleeved on and threadedly engaged with the supply pipe, and a shoulder formed radially from an inner surface of the tube section and abutting against the protrusion to thereby interpose the protrusion between the shoulder and the supply pipe. The sealing member establishes a watertight seal between the inlet and supply pipes. The sleeve member is selectively displaced on the inlet pipe to vary a depth of insertion of the inlet pipe in the supply pipe.
