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.

A gasket has an annular gasket base extending circumferentially about a gasket axis. A central flange extends inwardly away from the gasket base toward the gasket axis. The central flange has an apex positioned at a first distance from the gasket axis. A first arm is spaced apart from the central flange and extends radially and inwardly away from the gasket base toward the gasket axis. The first arm includes a first sealing portion. The first sealing portion defines a first sealing surface spaced apart from the gasket axis by a second distance which is greater than the first distance. A second arm is spaced apart from the central flange and extends radially and inwardly away from the gasket base toward the gasket axis. The second arm includes a second sealing portion defining a second sealing surface.

A coupling for coupling pipe segments (). The coupling includes a first housing component (), a second housing component (), and a fastener coupling the first and second components together. The fastener () has an aligned configuration defining an axis of alignment such that first and second housing components are in a closed configuration to define a central axis of the coupling. The fastener has a skewed configuration to define a pivot axis of the fastener such that the first and second housing components are in an open configuration. The pivot axis is substantially parallel to the central axis and substantially perpendicular to the axis of alignment.

Coupling devices for joining pipe ends include annular gaskets. Example gaskets include pipe interface profiles for sealing performance and manufacturability.

An apparatus for cold rolling a piping element connection with multiple outward steps has first and second rollers, a driver for the second roller, and a positioning roller. The first roller rotates about a first axis, with first and second upper surfaces of rotation centered thereabout, the first surface mean diameter being less than that of the second surface. The first roller has an upper leading edge between the first and second upper surfaces. The second roller is mounted for rotation about a second axis parallel to the first axis, with first and second lower surfaces of rotation centered thereabout, the first surface mean diameter being less than that of the second surface, and the second roller having a lower trailing edge between the first and second lower surfaces. The first and second rollers are mounted for movement together and apart in a plane of the first and second axes for engagement and cold rolling of multiple outward steps in the piping element connection placed therebetween which are essentially parallel to the centerline of the piping element connection that is positioned therebetween.

A coupling construction includes a plurality of coupling segments which are receivable in substantially end-to-end encircling relation around the end portions of a pair of grooved pipe sections and a plurality of nut-and-bolt assemblies for securing the coupling segments together. The coupling segments include arcuate main portions, apertured flanges which extend outwardly from opposite ends of the main portions and spaced first and second ridges which extend inwardly from the inner sides of the main portions and are receivable in annular grooves in the pipe sections. The apertures in adjacent flanges are offset from each other in a direction substantially parallel to the Z--Z axis of the coupling so that tightening of the nut-and-bolt assemblies causes adjacent flanges to be drawn into predetermined offset positions before the end faces of the coupling segments are drawn into engagement. When the adjacent flanges are in the offset positions thereof, opposite end portions of the ridges are urged against opposite side edges of the grooves to secure the pipe sections in predetermined closely spaced, aligned positions. The adjacent end faces of the coupling segments are disposed in angular planes and they are engageable in face-to-face relation so that they cooperate with nut-and-bolt assemblies to provide a wedging action for retaining the adjacent ends of the coupling segments in offset positions.
