摘要： A head adapter for a fire sprinkler includes a body defining a volume. The body has an elbow shape and includes a first opening that couples with a fluid supply line and provides fluid communication between the fluid supply line and the volume of the body and a second opening that provides fluid communication between the volume of the body and the fire sprinkler. The second opening includes a gasket. The body also includes a cap coupled with the open second end of the body such that the gasket is disposed between the cap and the volume. The cap couples the body to the fire sprinkler to provide fluid communication between the fluid supply line and the fire sprinkler. The volume of the body is shaped such that fluid from the fluid supply line is directed to the fire sprinkler.

摘要： A sprinkler assembly includes a fire protection sprinkler and a push-to-connect-rotate-to-release (PCRR) fitting. The fire protection sprinkler has a body defining an inlet and an outlet, a deflector spaced from the outlet, the body having an outer encasing surface surrounding a first longitudinal axis, the outer encasing surface including a seal member disposed about the encasing surface and a helical surface between the deflector and the seal member. The PCRR fitting includes a tubular member with a first end, a second end, an exterior surface, and an inner surface defining an internal conduit extending along a second longitudinal axis, the body received in the internal conduit such that the first longitudinal axis is axially aligned with the second longitudinal axis, the inner surface including a sealing surface portion circumscribed about the second longitudinal axis. The gripper ring is disposed along the inner surface and in contact with the helical surface.

摘要： A two member plastic pipe fitting adapter for installing a threaded sprinkler head. The members are coupled together to form a chamber for housing an annular gasket. The gasket chamber includes an expansion void and bearing surfaces for the gasket. The adapter includes a receptacle with an internal thread for engagement with a sprinkler head to load the gasket and form a fluid tight seal. The engagement between the sprinkler and the adapter is formed by dissimilar threads to minimize the outward radial forces on the adapter.

摘要： A fire protection system can include one or more pipes coupled with a fluid source, a pipe fitting coupled with the one or more pipes downstream of the fluid source, and at least one sprinkler coupled with the one or more pipes and the pipe fitting. The pipe fitting can include a wall defining an opening, the wall having an outer diameter, a first wall thickness at the opening, and a second wall thickness inward from the opening, the second wall thickness greater than the first wall thickness. The at least one sprinkler can be coupled with the one or more pipes and the pipe fitting to receive fluid from the fluid source through the one or more pipes and the pipe fitting.

摘要： A gasket installation tool for installing a gasket member within an internal gasket chamber of a sprinkler head adapter or fitting. The installation tool includes a tubular assembly that engages the sprinkler head fitting and provides a passageway into which the gasket member is loaded. A rod member engaged with the tubular assembly advances the gasket member through the passageway of the tubular assembly to radially compress the gasket member. The engagement between the rod member and the tubular assembly controls the advancement of the gasket member into the fitting to properly locate the gasket within the chamber and prevent over travel.
