Abstract: A fitting for use with metallic pipe is disclosed. The fitting includes a body having a connection portion and an opening for receiving an end of the metallic pipe in an insertion direction along a longitudinal axis of the connection portion, a retainer positioned within the connection portion coaxial with the longitudinal axis, the retainer having a plurality of prongs extending radially towards the longitudinal axis, and a gripper positioned within the connection portion coaxial with the longitudinal axis between the retainer and the opening. The gripper is configured as a frusto-conical compression ring tapering towards the opening and has a plurality of gripping projections extending radially towards the longitudinal axis. In operation, the gripper and connection portion cooperate to increase compression on the metallic pipe if the metallic pipe is urged out of the fitting.

Abstract: A poppet-style check valve for allowing uni-directional flow in a fluid conducting system. The check valve comprises a valve body, and a poppet mounted therein for reciprocal axial movement between a first position in which the poppet is pressed against a valve seat restricting flow through the check valve, and a second position in which the poppet is spaced from the valve seat permitting flow through the check valve. An inner bore of the valve body is expanded in the area of the poppet to maximize flow through the check valve, and the external dimensions of the check valve are minimized by eliminating a conventional liner between the poppet and the valve body. Additionally, the elements of the valve mechanism are designed such that they lock in place within the valve body during assembly.

Abstract: A coupling for connecting pipes to externally threaded fittings and stubs. The coupling comprises a coupling body, a gripper, gripper engagement means for causing the gripper to engage the pipe, a gasket, gasket engagement means for causing the gasket to seal around the pipe, gripper retention means for retaining the gripper within the interior of the coupling body during handling thereof, and gasket retaining means for retaining the gasket within the interior of the coupling body during handling thereof.

Abstract: A water meter idler bar for use during manufacture, shipping and installation of a water meter setter to ensure and maintain proper alignment and spacing between water meter fittings of the water meter setter. Following installation, the idler bar also allows water to flow through the water meter setter prior to installation of a water meter. The idler bar is a rigid PVC pipe having threaded connectors with rubber O-rings at its ends.

Abstract: A coupling for creating a fluid-conducting connection between a pipe and a stub, where the stub has no pipe-supporting extension over which the pipe is to be connected. The coupling includes a coupling body having a forward end for being secured to the stub, a rearward end for receiving the pipe, and an internal bore therethrough; stub connection for securing the forward end of the coupling body to the stub; a pipe support for providing internal support for an end section of the pipe being engaged by the coupling; gripper engaging means for causing the gripper to grip the pipe; a seal between the stub and the pipe; and a gripper located within the internal bore of the coupling body, the gripper and the coupling body configured to engage the pipe with the gripper when the stub is secured in the stub connection.
