    摘要： A drain flusher device for dislodging an obstruction in a pipe. The drain flushing device has an elastomeric cylindrical body with an open neck end and nose portion having a thickened end wall. An elongated slit with a predetermined configuration and predetermined dimensions extends through the thickened forward end wall. A connector is fixed at the body neck end and is adapted for attachment to a pressurized fluid source, such as a garden hose.

    摘要： A two piece mechanical plug assembly for sealing low pressure pipelines. The mechanical plug assembly comprises a rigid body member and a flexible, cylindrical sealing member. The rigid body member has an upper portion and a lower portion of a frustoconical configuration having a plurality of threads. The sealing member has a conical bore with a plurality of threads to receive the lower threaded portion of the rigid body member. The upper portion of the rigid body member has an upwardly extending member with opposing wing members for turning the rigid body member into the sealing member whereby the rigid body member expands the flexible sealing member for sealing engagement into the interior of a pipeline.

    摘要： A frangible sealing plug for pipelines comprising a unitary disc shaped fluid impermeable body having a plurality of score lines on one side, and a peripheral score line on the opposite side adjacent a peripheral sealing structure. The peripheral sealing structure abuts the end of a pipeline section. The impermeable sealing plug is preferably molded of a plastic composition. The plurality of score lines includes at least one radially disposed score line and at least one concentric score line. The frangible sealing plug is positioned in the end of a pipeline section to hold a testing fluid backpressure. After testing, the disc shaped body is separated into a plurality of pieces along the score lines by a removal device.

    摘要： A pneumatic test plug for clean-out tees having an elastomeric inflatable body, a closed top, an inwardly tapered side wall and an open bottom end with a peripheral shoulder having a downwardly extending peripheral ridge. A molded end cap with a cylindrical wall having exteriorly disposed threads and an inwardly disposed circular retention channel or area receives a retention collar for placement within the molded end cap and between the cylindrical wall and the inflatable body bottom end. The retention collar fixes the peripheral shoulder and downwardly extending peripheral ridge in the circular retention channel or area of the end cap and compressingly holds the peripheral shoulder of the inflatable body into the end cap.

    摘要： A mechanical plug device for sealing pipeline access ports having a small threaded inner surface. The mechanical plug device has opposing inner and outer circular plate members. The rigid plate members each have interiorly tapered circumferential shoulders of generally the same predetermined slope. The inner plate member has an inner surface, an outer surface, a central aperture and a central cavity extending inward from the tapered circumferential shoulder. The outer circular plate member has an inner surface, an outer surface, a central aperture and an outwardly extending structure from the tapered circumferential shoulder for movement into the central cavity of the inner plate member. The device further has an elastomeric radially expandable pre-threaded O-ring structure which has an outer circumferential threaded surface configuration. The O-ring structure has a V-shaped bottom cross-section defining inclined surfaces of a predetermined slope. The device has an adjustable lateral force structure active between the inner and outer plate members to adjust and position the O-ring structure on their opposing circumferential shoulders.
