A sprinkler assembly includes a fire protection sprinkler and a push-to-connect-rotate-to-release (PCRR) fitting. The sprinkler has a body with a passageway extending along a first longitudinal axis and an outer encasing surface surrounding the first longitudinal axis and outer encasing surface including a seal member, and a deflector spaced from the outlet. The fitting includes a tubular member including an exterior surface and inner surface, the 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 aligned with the second longitudinal axis, the inner surface including a sealing surface portion circumscribed about the second longitudinal axis. The fitting includes a gripper ring disposed along the inner surface and a helical internal periphery about the second longitudinal axis in helical contact with a portion of the outer encasing surface between the deflector and seal member.

A gripper for a pipe connector includes a body, a first tooth, and a second tooth. The body has a first side, a second side adjacent the first side, a third side adjacent the first side and opposite the second side, and a fourth side adjacent the second side and the third side and opposite the first side. The first tooth extends from the fourth side of the body at a first distance from the first side of the body perpendicular to the first side of the body. The second tooth extends from the fourth side of the body at a second distance from the first side of the body perpendicular to the first side of the body. The second distance is less than the first distance.

A press fitting device, components and method provide one or more indicators to provide a visual indication that the fitting has been properly pressed around a tube and that the correct amount of pressure has been provided to create a permanent seal. In embodiments, a sealing ring and a latching band are retained within a main body component of the fitting and the latching band can be formed with a radially inwardly extending latch that extends through an opening in the sealing ring.

A preassembled combination connects a captured pipe element to a second pipe element. First and second segments are connected end to end surrounding a central space for axially receiving the second pipe element. The segments are configured to be drawn toward one another and into engagement with the pipe elements. An annular body forms the captured pipe element. An end face of the captured pipe element is retained within the central space by engagement between a bead projecting from a sealing surface of the captured pipe element and the coupling assembly.

The invention provides an articulated joint in a pneumatic conveying system of a boom of an agricultural dry product applicator. The joint allows adjacent product-conveying tubes and respective joint components to articulate with respect to each other while maintaining a seal for pneumatically conveying product. Joint components may be separated from each other when the boom is folded while articulating with respect to each other without disengaging or creating potential leaks at segment junctures while the boom is extended. The articulated joint includes a rigid socket having a first socket section and a second socket section providing support to a compressible seal having a first seal section and a second seal section. The first seal section is inserted into the second socket section to create an airtight seal in between the first seal section and the second socket section even when boom tube segments flex during use.
