ABSTRACT:
An insulator is designed to mount 3/8, 1/2 or 3/4 inch pipe in a hole through a sheet metal wall stud. The pipe insulator includes a generally cylindrical body that fits within a circular hole pre-punched in the intermediate planar portion of the sheet metal wall stud. The body has a circular, radially extending mounting flange which is held against the periphery of the hole in the sheet metal stud by a plurality of axially extending, circumferencially spaced mounting fingers formed in the cylindrical body. These mounting fingers momentarily deflect out of the way and then snap back into position when the cylindrical body is forced into the hole in the sheet metal stud. The pipe insulator further includes axially spaced sets of pie-shaped pipe gripping segments which extend radially inwardly from the cylindrical body and bend a sufficient amount to permit passage of the pipe through the center of the cylindrical body while holding the pipe rigidly in position. The pie-shaped gripping elements are resilient and flexible and accommodate the three different sizes of pipe.
