An indicator assembly includes a fastener defining a first end, a second end opposite the first end, and an axis extending from the first end to the second end; a first indicator positioned radially outwardly of the fastener relative to the axis of the fastener; and a second indicator positioned radially outwardly of the fastener relative to the axis of the fastener, wherein the second indicator is axially in between the first indicator and the second end of the fastener upon the fastener being oriented in a first position, and wherein the second indicator is radially inwardly or radially outwardly of the first indicator upon the fastener being oriented in a second position.

A conduit coupling assembly having an arcuate clamp ring having first and second longitudinal edges, a spanner configured to extend across a longitudinal ring gap between the first and second longitudinal edges, a connecting assembly configured to tighten the spanner and clamp ring to the fluid conduit from a non-actuated position to a tightened position, an arcuate gasket configured to be positioned between the clamp ring and spanner on an outer side of the gasket and the fluid conduit on an inner side of the gasket, and the gasket comprising a spanner recess in the outer side of the gasket configured to receive at least a portion of the spanner.

A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides a restrained pipe joint including a first pipe including a bell with a spigot entryway and a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of restraining segments is at least partially embedded in the gasket.

A sealing arrangement includes: a first pipe and a second pipe, which are arranged substantially adjacent to each other in a flow direction and together form a line, the first pipe having a first end and the second pipe has a second end, the first end enclosing the second end at a radial spacing; and a sealing sleeve comprising a sealing material, the sealing sleeve being sealingly arranged under radial elastic preloading in a gap formed by the spacing and sealingly contacting an inner circumference of the first pipe and an outer circumference of the second pipe.

A duct coupler has a body with an inner wall with a first channel and a second channel formed in the inner wall, a first seal received in the first channel, and a second seal received in the second channel. The body has a first open end suitable for receiving a first duct therein and a second open end at an opposite end thereof suitable for receiving the second duct therein in longitudinal alignment with the first duct. The first seal is suitable for bearing on an outer surface of the first duct. The second seal is suitable for bearing on the outer surface of the second duct. The body fixedly locks the first and second ducts therein such that the ends of the ducts are adjacent to each other and such that the body forms a liquid-tight seal with outer surfaces of the ducts.

Provided are connector assemblies for connecting pipes. For example, a connector assembly can include a connector formed with a hollow into which a pipe is inserted. A large diameter portion on at least one side of both end portions of the hollow where the large diameter portion is formed has a relatively large inner diameter and a housing space inside. The connector assembly also includes a ring-shaped sealing member provided in the hosing space and a grip member provided adjacent to the sealing member in the housing space. Further, the grip member has a body portion formed to contact an inner circumferential surface of the large diameter portion and a pair of sharp portions formed to be bent from both sides of the body portion and to partially bite into the outer circumferential surface of the pipe by crimping the outer circumferential surface of the large diameter portion.

A rigid entry fitting configured to form a seal between a flexible pipe segment and a sump wall includes a fitting body having an inner surface defining a tapered opening, an insert received in the tapered opening, a shell received in an opening of the insert, a first pair of gaskets between an outer surface of the insert and the inner surface of the fitting body, a second pair of gaskets contacting an inner surface of the shell and opposite ends of the insert, and a nut configured to engage threads on an outer surface of the fitting body. When the nut is threaded onto the threads, the nut presses the shell and the insert into the tapered opening and presses the first pair of gaskets against the inner surface of the fitting body and the second pair of gaskets against the outer surface of the flexible pipe segment.
