A pipe coupling comprising a housing with a receiving space for a pipe section, with fixing members for releasably fixing the pipe section in the housing, and a sealing element which is arranged in the receiving space and is designed to surround the free end of the pipe section received in the receiving space on the outer circumferential side and thereby seal the interface between the housing and the pipe section in a fluid-tight manner. The pipe coupling is characterized in that the sealing element is designed in the form of a sleeve with a first and a second free end, in that a bulge is provided at the first free end, and in that a tubular section protrudes from the bulge and forms the second free end on the edge side.

A joint assembly can include a piping element and a fastener configured to secure a pipe length to the piping element, the fastener including: a nut; a gasket positioned at least partially between the nut and the piping element; and a grip band positioned at least partially between the nut and the gasket, the grip band defining a first axial end and a second axial end, the grip band including a plurality of teeth extending from the first axial end, each of the plurality of teeth configured to rotate with respect to an axis of the grip band in transition between an uncompressed condition and a compressed condition to change a corresponding angle of attack of each of the plurality of teeth with respect to the pipe length.

Irrigation line couplings are disclosed. The irrigation line couplings may each include a lockable release mechanism that may be positioned in a locked position or a released position. The irrigation line couplings may be incorporated into an irrigation manifold or other type of irrigation component, such as fittings (tees, elbows, etc.), valves, filters, pressure regulators, emitters, and adapters.

A connector is provided comprising a hollow connector body having a central aperture and a hollow tube that is rotatable within the central aperture without rotating the hollow connector body.

A connector is provided comprising first and second hollow connector bodies, the connector having a first expanded position providing a first fluid flow path through the first hollow connector body, and a second collapsed position providing a second fluid flow path through the first and second hollow connector bodies.

The invention is a tapping assembly for use on a pipe or tank. It includes a hollow body that sits flush on the outer wall of the pipe or tank and includes a plurality of locking members that sit flush within the body and form a threaded portion into which a cap is inertable. Each locking member extends into the interior of the pipe or tank, and has an outwardly extending flanged portion that engages with the inner sidewall of the pipe or tank. When the cap is tightened against the body, it causes each of the locking member to retract, thereby causing the respective flange portions to lock the assembly against the pipe or tank wall. The assembly can be manufactured to provide either an orthogonal tap, or an angled tap, relative to the longitudinal axis of the pipe, or plane of the tank sidewall.

A push-to-connect joint assembly, device and method include a fitting formed with an interior wall having axially inner, axially intermediate and axially outer portions that facilitate re-use and repair of push-to-connect fittings and valves without damage to the fitting or valve elements or the pipe, and without coining, gluing or threaded engagement of parts. In embodiments, a packing arrangement inserted into a fitting includes a sealing member, a fastening ling, a seat ring, and a retainer including a shield member and/or a seat retainer.

A construction system for a connection arrangement for media lines, wherein the connection arrangement has a connection body with a receiving opening for a media line and with internal parts for interacting with the media line and providing axial guidance, mechanical locking to prevent detachment, peripheral sealing and, where applicable, internal radial support. Various internal parts can optionally be inserted into the connection body, which is designed to be identical in respect of the internal contour of the receiving opening, and for a particular maximum external line diameter, in order to adapt to at least two dissimilar media lines having different cross-sectional dimensions. The internal parts are adapted, on the one hand, to the permanently identical internal contour of a receiving opening of the connection body and, on the other hand, to the cross-sectional dimension of one of the dissimilar media lines.

A tube connector for attachment to an end of a tube of a pressurized fluid system has a housing, a main sealing element, a gripping element and a cone element. The main sealing element is arranged for sealing an inner surface of the housing to an outer surface of a tube. The gripping element comprises a gripping edge for engaging with an outer surface of a tube. The cone element limits a movement of the grip-ping element. The tube connector further has an integrated release element. The release element has a tubular part, a top part and an environmental sealing. A release edge of the tubular part engages with the gripping element and the environmental sealing is adapted for sealing a receptacle formed in the housing of the environment.

Embodiments of a swage connector device and assembly include one or more of a sealing ring, a fastening ring spreader, a retainer grip ring, a cap member and a fastener push ring. The fastener push ring moves axially and engages the fastening ring spreader in order to securely maintain a piping element held within the fitting.
