Abstract
A unitary tubular fitting body and cooperating mandrel for installation on a blind wall. The body includes an axially collapsible tube portion which during installation draws up the body into alignment with the wall. The body includes a frangible ring dimensioned to fail after adequate compression force is applied on the collapsing tube portion for full sealing engagement with the wall. Failure of the ring releases the mandrel and prevents overtightening of the fitting.
