A seal assembly is configured for use at PVCO pipe junctions. The seal assembly includes a main seal body made of a monolithic resilient material, such as rubber, and a stiffener. The seal has a stiffener pocket sized and configured to accept the stiffener, such that the stiffener can be assembled to the seal body by hand. This assembly can then be installed into the bell end of a first PVCO pipe, and a spigot end of a second PVCO pipe may then be inserted into the bell end and engaged with a main sealing lobe of the seal assembly. The seal assembly is configured to reliably withstand the insertion process, without damage or degradation to the sealing structures. Once installed, the seal assembly provides a robust fluid-tight seal along all potential leak paths between the seal assembly and the first and second pipes.

Hole former with gasket locating features for cast manhole structures
A hole former for use in casting a gasket within an opening of a structure of the type used in underground water systems, such as a manhole. The hole former includes a body defining a central axis and an outer peripheral surface, with at least one gasket retention element projecting radially outwardly from the outer peripheral surface to interface with a corresponding locating feature of the gasket. In this manner, axial shifting or movement of the gasket with respect to the hole former is restricted, thereby positively locating and retaining the gasket on the hole former before and during the casting process. The hole former may have a compound curvature, with the gasket retained around the periphery of the hole former in a compound curved configuration.

A sealing assembly has an expansion band having an arcuate band portion and a pair of threaded end portions formed at opposing ends of the arcuate band, in which the arcuate band and threaded end portions are monolithically formed as a single piece. Fixed within respective threaded end portions are a pair of oppositely threaded nuts adapted to receive a bolt having correspondingly oppositely threaded ends. Rotation of the bolt causes the threaded end portions to be simultaneously driven apart or drawn toward one another (depending on the rotation direction of the bolt) to thereby expand or contract the overall outer profile of the arcuate band portion. The monolithically formed expansion band may be made of an inexpensive, non-rusting material such as nylon 66, and glass fibers and/or additives may be employed to impart strength and flexibility.

A sealing system seals the perimeter of insulated hinged double doors. The sealing system includes first and second exterior seals made of a monolithic, resilient and elastically deformable material. The first exterior seal has an elongated lobe for contacting the exterior of said door, and both of the first and second exterior seals have an interior lobe which contact one another when the doors are closed. The sealing system further includes first and second inner seals made of a monolithic, resilient and elastically deformable material, each having a pair of spaced-apart sealing lobes. The inner seals are mounted to respective doors in a staggered fashion, such that the respective pairs of sealing lobes interact with one another to create a redundant, weather-resistant and thermally robust seal when the double doors are closed.

An expansion ring assembly seals a gasket with respect to an annular wall of a rigid structure. The expansion ring assembly includes two arcuate expansion ring bands that cooperate to define a generally circular profile. At one side of the expansion ring assembly, a first pair of ends of the expansion ring bands overlap and include a ratcheting mechanism which allows the ring to incrementally expand but not to contract. At another location of the expansion ring assembly, a second pair of ends are joined by a drive mechanism for engaging and driving apart the opposing ends of an expansion ring to thereby non-incrementally expand the ring. The ratchet mechanism may be used to initially set and hold the expansion ring against a gasket in a desired position and to provide an initial expansion pressure, i.e., for a coarse adjustment. The drive mechanism may then be used to provide a final expansion pressure of the gasket, i.e., for a fine adjustment. Advantageously, the coarse adjustment followed by the final adjustment allows a user to quickly and precisely achieve a desired gasket pressure by manipulating the torque applied to the drive mechanism.
A gasket and mandrel assembly, including a gasket having an annular main body portion with an anchor flange and a pipe sealing portion. The gasket is foldable between a folded position in which the pipe sealing portion is disposed substantially within the main body portion and an unfolded position in which the pipe sealing portion extends outwardly of the main body portion along its longitudinal axis. A pair of mandrels are respectively fitted on opposite sides of the folded gasket to enclose most of the gasket for casting the gasket within a wall in a concrete structure. At least one of the mandrels includes an annular outer surface aligned parallel or substantially parallel with the longitudinal axis of the gasket. Removal of the mandrels results in the cast opening in the concrete structure having a circular inner surface which is disposed parallel or substantially parallel to the longitudinal axis of the gasket and the resulting opening such that, if the gasket should fail, the gasket may be removed from the opening and an expansion-type gasket may be sealingly compressed against the opening surface with an expansion band assembly.

Expansion ring assembly with removable drive mechanism
An expansion ring assembly for sealing a gasket within an opening in the wall of a structure, the assembly including a drive mechanism having a pair of block members each having a threaded bore, and a bolt having oppositely threaded ends respectively threaded within the bores. The block members are removably engaged with respective ends of the expansion ring. An oversleeve is disposed in overlapping relationship with the expansion ring ends, and the expansion ring ends and the oversleeve include cooperating ratcheting structures. Rotation of the bolt of the drive mechanism in a first direction causes the block members to move outwardly along the bolt to expand the expansion ring and concurrently sequentially engage the ratcheting structures of the expansion ring ends and the oversleeve.
