Abstract: A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.

Abstract: A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base. First and second, spaced apart, funnel shaped, diaphragm seals are connected to a first tubular passage or an adjustable length tubular extension. A cap for closing either tube has an inclined outer surface to form a beveled entrance to the passage in the concrete. An aerator box may be connected to the base. Hinged ends on the base allow the shape and length of support to be altered.

Abstract: A support for pipes uses a telescoping strut slidably holding an elongated insert with a threaded post extending outward from the insert, through a slot in the C-shaped cross-section of the struts. A bracket fits over the post and abuts supports opposing edges of the strut. A nut on the post clamps the parts immovably together. The bracket has a depending portion extending below the strut with an opening through which a pipe passes. Two threaded couplers with opposing ramped surfaces encircle the pipe and deform when tightened to clamp the pipe while also clamping opposing sides of the depending portion.

Abstract: A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.

Abstract: A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position.

Abstract: A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal recess cooperating with a test slide to block flow through the fitting. An externally accessible port allows insertion and removal of the test slide. The test slide has an internal recess in which a pressure release slide moves to open a hole to release pressure, and to close the hole to block flow through the fitting for pressure testing. After testing and the release of the fluid test pressure, the test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.

Abstract: A clamp assembly releasably secures a plumbing pipe to a support. The assembly has a clamp base releasably connected to a clamping block by pawls that releasably engage a pair of ratchet arms extending from the base. Each of the base and clamping block has two inclined surfaces forming a generally V-shaped notch that opens toward the pipe. A cap is optionally placed over one or both of the V-shaped notches and is interposed between the notch and the pipe. At least one resilient leg or a flange may extend from the base opposite the ratchet arms, with the flange and/or the arms resiliently engaging opposite sides of the support to hold the clamp assembly in position.
