Abstract: A device for arresting a shock wave in a fluid in a pipe assembly. The device includes a base, body, and piston. The base has a connector portion with a first opening into an interior. The connector portion is configured to be coupled to the pipe assembly and allow the fluid to flow into the interior through the first opening. The body has an open end opposite a closed end and a channel that extends from the open end into the closed end. The open end is positioned inside a second opening into the interior of the base. Together the base and body form a housing in which the piston is positioned. The piston is slidable within the housing from a resting position to a compressing position when the shock wave travels through the pipe assembly. The piston compresses a gas inside the housing when in the compressing position.

The members being resiliently bendable between a first position with the inward free-end portions being in gripping contact with the pipe and a second position with the inward free-end portions defining a central insert opening sized to permit the insert to pass by the ferrule on the pipe as the escutcheon is pressed onto the pipe and then return to the first position.

Abstract: A utility box for mounting at least in part within a wall for use with a fluid carrying supply pipe, the box comprising, a housing including a top wall, a bottom wall, a first side wall and a second side wall, a back wall and a front opening providing access into an interior of the housing defined by the top, bottom, first side, second side and back walls, a bottom wall aperture in the bottom wall sized for extending the pipe through the bottom wall aperture with the pipe terminating in a free end portion positioned within the interior of the housing at a location above the bottom wall, a valve attachable to the free end portion of the pipe, the junction of the valve and the pipe being within the interior of the housing above the bottom wall, and a first seal positioned to provide a fluid-tight seal between the bottom wall and the pipe to prevent fluid within the interior of the housing from passing out of the interior of the housing through the bottom wall aperture.

Abstract: A valve and adapter for coupling a tubing to the valve. The adapter has first and second adapter end portion with connected fluid passageways. The second adapter end portion being insertable into the free-end portion of the tubing. A valve housing has a first chamber sized to receive the first adapter end portion and a second chamber has inward and outward fluid ports. When the first adapter end portion is positioned within the first chamber, an outer end portion of its fluid passageway is in fluid communication with the inward fluid port of the second chamber. A seal and gripper ring within the first chamber seal with and releasably grip the first adapter end portion. A valve element selectively control fluid flow between the first and second fluid passageways. The adapter may be used with a test cap and other fittings which include a seal and a gripper ring.

Abstract: A plumbing fitting couplable with a free-end portion of a pipe. The fitting has a chamber with an opening and an interior chamber wall with a circumferentially extending chamber groove, and an end bushing with an interior opening sized to receive the pipe free-end portion and an exterior wall portion having an outwardly projecting, circumferentially extending locking member within the chamber groove to resist movement of the end bushing out of the first chamber opening. A seal and gripper ring within the chamber seal with and releasably grip the pipe free-end portion. The end bushing interior opening has an end bushing interior wall portion sized to be engaged by the free-end portion of the pipe when within the end bushing interior opening to resist disengagement of the locking member from the chamber groove while the free-end portion of the pipe is within the end bushing interior opening.

The piston compresses a gas inside the housing when in the compressing position.

Abstract: A utility box for mounting at least in part within a wall for use with a fluid carrying supply pipe, the box comprising, a housing including a top wall, a bottom wall, a first side wall and a second side wall, a back wall and a front opening providing access into an interior of the housing defined by the top, bottom, first side, second side and back walls, a bottom wall aperture in the bottom wall sized for extending the pipe through the bottom wall aperture with the pipe terminating in a free end portion positioned within the interior of the housing at a location above the bottom wall, a valve attachable to the free end portion of the pipe, the junction of the valve and the pipe being within the interior of the housing above the bottom wall, and a first seal positioned to provide a fluid-tight seal between the bottom wall and the pipe to prevent fluid within the interior of the housing from passing out of the interior of the housing through the bottom wall aperture.

Abstract: A coupling having a housing with an internal bore sized to receive a tube therein, a spacer bushing non-movably retained against axial movement within the bore, and first and second gripper rings each having a peripheral portion non-movably retained against axial movement within the bore prior to and during operation of the coupling with the tube therein with teeth protruding inwardly into the bore sufficient to engage the tube. The gripper teeth being non-retractable, and the gripper rings and spacer bushing being held tightly together within the housing. The coupling may include a seal for application of pressurized fluid to the tube.

Abstract: An enhanced escutcheon cover plate includes a plate body and an opening having a periphery and surrounded by the plate body. The enhanced cover plate further includes a flexible portion extending from the plate body along portions of the periphery of the opening. The flexible portion is elastically moveable between a first position and a second position. In the first position, the flexible portion can define a first passageway for piping to be received through the opening. In the second position, the flexible portion can define a second passageway larger than the first passageway. A pipe can be slid through the opening while the flexible portion is in the first position. A compression ferrule affixed to the pipe can be slid through the opening while the flexible portion is in the second position.
