Abstract
Adjustable fire protection assemblies and methods are provided. The assembly includes a sprinkler having a body with an outer encasing surface and a deflector supported from the body. An escutcheon having a receiver and a rim surround the fire protection sprinkler to define an aperture between the receiver and the sprinkler. A push-to-connect fitting of the assembly includes a tubular member with an end for connection to a pipe and an internal conduit that receives the sprinkler body. A seal member and a retaining ring are disposed within the tubular member to form an adjustable seal and grip about the sprinkler body. A releasing member translates to disengage the retaining ring from the sprinkler body; and the escutcheon translates with respect to the tubular member in a sliding surface engagement to define an adjustable deflector-to-rim distance between the rim of the escutcheon and the deflector of the sprinkler.
