A holding apparatus and method for installing a first threaded end of a pipe fitting onto a pipe, where the first threaded end has a first thread axis, and the pipe fitting has a second threaded end with a second thread axis oriented at an angle of less than 180 degrees with respect to the first thread axis. A holder engages the pipe fitting such tha t the first threaded end extends from an open end of the holder, and a wrench head is fixed to the holder opposite the open end and is rotated by a wrench about a head axis. T he wrench head and holder are configured such that when the pipe fitting is engaged in the holder, the head axis is aligned with the first thread axis and rotating the wrench head about the head axis rotates the pipe fitting about the first thread axis.
