摘要： A fluid quick connector incorporating Graphene or Graphene Derivatives into engaging male and female end forms that reduces oxygen and water permeation through the coolant quick connector and includes an integrated latch that eliminates the need for a separate latch component. An integrated retainer is located within the mating interior interface of the female end form and opposing exterior interface of the male end form and, in combination with an EPDM O-ring component, provide for a fluid sealing connection between the end forms which reduces permeation of oxygen and water through the body as well as reducing coolant volume loss so as to maintain an ideal (typically 50/50) water to Glycol ratio.

摘要： A pipe sealing gasket is shown which is designed to be received within a raceway provided within the female, belled end of a section of plastic pipe which is assembled with a mating male pipe end to form a plastic pipe joint. The gasket is a two-component gasket having a softer, elastomeric portion and a harder, plastic ring portion. A splicing technique is used to form the softer, elastomeric portion with the harder, plastic portion being injection molded over the previously formed elastomeric portion.

摘要： Pipe sections are often connected together with a spigot end received within a bell end and a gasket provided there between. An assist may be helpful to apply at least a tension if not move the gasket towards a gap between the bell end and an exterior surface of the spigot end of the two pipe portions, and/or against the exterior surface of the spigot end so as to improve the likelihood of an adequate seal.

摘要： A pipe coupling assembly for coupling a first end portion of a first pipe with a second pipe includes a socket formed on an end of the second pipe and a locking ring. The socket includes a rim defining an end opening through which at least a portion of the first end portion is inserted, the rim including a rim sealing surface adapted to form a liquid-tight seal around the first end portion. The socket also includes a sleeve portion having an exterior surface and an interior surface defining an interior space for receiving the first end portion, the interior surface comprising at least two socket sealing surfaces adapted to form a liquid-tight seal around the first end portion. The locking ring is adapted to cause the rim sealing surface to compress to form a liquid-tight seal around the first end portion.

摘要： A polymer pipe has a length between a first end and a second end. The length and the first end have a first diameter and the second end is a belled end having a second diameter larger than the first diameter. An insert device is received or pre-installed within the second end and has an annular body with a seal part coupled to the annular body and a spline groove formed in the annular body and facing radially inward. Another polymer pipe is inserted in the belled end to form a pipe joint assembly and has a mating spline groove on the outer surface. The spline groove and mating spline groove axially align and receive a spline therein to axially interlock the two polymer pipes to form a pipe joint assembly.

摘要： A pipe system includes a tubular body having an axis, a bore extending in an axial direction, a tubular body retainer groove formed in the bore, and a tubular body exterior. Retainers are configured to be mounted in the tubular body retainer groove only from the bore of the tubular body. In one version, the retainers cannot be installed in the tubular body retainer groove from the exterior of the tubular body. The retainers are configured to be circumferentially spaced apart from each other with respect to the axis. In addition, a pipe having a pipe exterior with a pipe retainer groove is configured to receive the retainers to form a pipe assembly.

摘要： A first projection is formed on the outer periphery of a bulb part, a second projection is formed on the socket rear end of the bulb part, a tapered part is formed with a decreasing diameter from the inner periphery of a heel part to the inner periphery of the second projection, and a third projection is formed on the tapered part. A first dimension B from the first projection to the third projection in an inclination direction opposite to an inclination direction G of the tapered part is smaller than a second dimension C from the first projection to the second projection in a radial direction A.

摘要： A pipe sealing gasket is shown which is designed to be received within a raceway provided within a socket end of a female bell plastic pipe end which is assembled with a mating male pipe end to form a plastic pipe joint. The raceway in the female bell plastic pipe end is preformed during manufacture and the gasket is installed thereafter. The gasket has a rubber body portion which is reinforced by a hard plastic band formed as a series of integral, spaced wedges which are interconnected by a flexible ribbon. The gasket is flexible enough to be flexed and placed in the pipe raceway and yet the hard plastic band acts to prevent extrusion of the gasket during a variety of pressure conditions as well as preventing displacement during field assembly.
