摘要： A pipe coupling has segments attached end to end to define a central space that receives pipe elements inserted between the segments. The segments are supported on split rings received within grooves in each segment. The segments are supported in spaced relation in a preassembled state to permit insertion without disassembly of the coupling. The grooves in the segments have a floor surface with three surface portions. Two of the surface portions on each groove of each segment engage the split rings when the segments are supported in spaced relation.

摘要： A fitting has a conduit with a bore defined by a surface facing an axis coaxially located with respect to the bore. The surface may have three portions including a conical portion located proximate to the inlet of the conduit, a threaded portion located proximate to the outlet of the conduit and a cylindrical portion located between the conical and threaded portions. A gasket is positioned within the conduit. The gasket has an outer surface and an inner surface facing the axis. The gasket inner surface has angularly oriented lands. One of the lands faces the outlet and is engaged by a threaded component received by the threaded portion. Engagement between the component and the land compresses the gasket radially outwardly and longitudinally within the conduit. An angularly oriented shoulder guides the gasket into a redirection space defined by the conical portion (when present) as it deforms.

摘要： A coupling (10) for joining pipe elements, said coupling comprising:
first and second segments (12, 14) positioned end to end surrounding a central space (16) for receiving said pipe elements;
a spring assembly (18) joining a first end of said first segment to a first end of said second segment (14), said spring assembly biasing said segments (12,14) away from one another; and
an adjustable attachment assembly (56) joining a second end (58) of said first segment (12) to a second end (60) of said second segment (14), said adjustable attachment assembly (56) adapted to draw said first and second segments (12,14) toward one another and into engagement with said pipe elements.

摘要： A coupling has first and second segments (12, 14) attached to one another end to end surrounding a central space (16) for receiving pipe elements. A spring assembly (18) attaches the segments at one end and an adjustable attachment assembly (56) attaches the segments at the opposite end. The spring assembly biases the segments away from one another sufficient to permit insertion of the pipe elements into the central space while the segments are attached to one another. The coupling may include a split ring toothed retainer for coupling plain end pipe elements, or it may have arcuate keys which engage grooved or shouldered pipe elements.

摘要： A pipe fitting for plain end pipe is formed of housing portions defining receptacles for receiving pipe elements. The receptacles are coaxial with respective axes oriented angularly with respect to each other. Each receptacle has a channel that faces a respective axis with floors at different radii of curvature. Retainers are received within the channels. The retainers have teeth and one or more offset tabs that cooperate with the channels to prevent improper assembly of the fitting. Ring seals are received within channels positioned adjacent to the receptacles. The ring seals cooperate with the retainers to hold the segments in spaced relation sufficient to insert pipe elements into the receptacles when the fitting is pre-assembled. Apertures are provided in the receptacles to permit visual determination of the presence of the retainers post assembly.

摘要： Fittings, including elbow fittings and Tee fittings have bodies that surround a central space and define openings to receive pipe elements. Ribs surround the openings, and gaps are positioned between the ribs to permit deformation of the body when ends of the body in facing relation are brought together. The body may be formed of two housings or unitary in construction. The ribs may be grooved to accommodate toothed retainer rings providing mechanical engagement with pipe elements. The ribs have surfaces with radii of curvature that, when the ribs are undeformed, are substantially equal to the radii of curvature of the pipe elements they engage.
