| 20110037249 | PRESSURE-ENERGIZED PROBE SEAL FOR FEMALE HYDRAULIC COUPLING MEMBER - A probe seal for a female hydraulic coupling member has both internal and external pressure-energized seals. The outer wall or opposing ends of the seal have one or more pressure-energized seals for sealing between the body of the probe seal and the body of a coupling member in which the probe seal is installed. In certain embodiments, the generally ring-shaped probe seal has an annular fluid chamber in one or both end walls of the body of the seal. Hydraulic fluid under pressure may enter the annular fluid chamber and exert a generally radial force in response to a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal to the body of the female coupling member having such a probe seal. In “negative pressure” situations (i.e., when the ambient pressure exceeds the internal fluid pressure), seawater may enter an annular fluid chamber on the opposing end of the probe seal and similarly act to increase the sealing effectiveness of the probe seal to the body of the female coupling member. Annular, L-shaped, T-shaped or angled grooves in the inner wall of the seal form cavities and sealing projections that can be urged in an inward, radial direction by fluid pressure within an associated cavity to increase the sealing effectiveness between the body of the seal and the probe of a male hydraulic coupling member inserted in the receiving chamber of the female coupling member. | 02-17-2011 |

A receiving end of the second pipe includes a first flange, a second flange, a groove, and a sealant. The second flange extends further than the first flange. The groove is disposed at the pipe diameter and between the first flange and the second flange. The first flange has an inwardly angled face to meet the groove and the second flange has an outwardly angled face to meet the groove. The sealant is disposed in the groove to seal the plain end of the first pipe in the receiving end. The joint is formed by the cooperative alignment of the plain end being inserted into the receiving end and being sealed by the sealant. | 03-13-2014 |
| 20140084580 | Sealed Transverse Locking Pipe and Fittings - A pipe and fitting coupling system includes a first pipe, a second pipe, and a joint. A receiving end of the second pipe includes a first axial flange, a second axial flange, an axial groove, and a sealant. The second axial flange extends further axially than the first axial flange. The axial groove is disposed at the pipe diameter and between the first axial flange and the second axial flange. The first axial flange has an inwardly angled face to meet the axial groove and the second axial flange has an outwardly angled face to meet the axial groove. The sealant is disposed in the axial groove to seal the plain end of the first pipe in the receiving end. The joint is formed by the cooperative alignment of the plain end being inserted into the receiving end and being sealed by the sealant. | 03-27-2014 |

| 20090146417 | Coupling Gaskets and Associated Methods - Various embodiments of the present invention provide improved coupling devices for joining pipe ends that have improved sealing performance and manufacturability over known pipe coupling devices. One of the improvements provided by embodiments of the present invention is a unique design of the gasket. Various embodiments of the gasket include an innovative pipe interface profile that improves the manufacturability of the gasket itself and its sealing performance. | 06-11-2009 |
| 20100102549 | GROOVED TRANSITION COUPLING - A pipe coupling and gasket, a pipe coupling system, and installation method for joining and sealing adjoining pipes having different outer diameters. The gasket including three flanges extending radially inward, with the middle flange acting as a fulcrum against the outer surface of the larger pipe to cause distension of the opening of the gasket receiving the smaller pipe, to permit easy entry of the smaller pipe into the gasket. The gasket is then slid over the larger pipe so that the middle flange slips over the edge of the larger pipe to relax the opening of the gasket receiving the smaller pipe. The middle flange can also form a sealing surface on the outer diameter surfaces of the larger pipe or on both the larger and smaller pipes. The middle flange can also form a sealing surface against the radially extending end surface of the larger pipe. | 04-29-2010 |
| 20140327238 | Coupling Having Arcuate Stiffness Ribs - A coupling for joining pipe elements end to end has a unitary band surrounding a central space for receiving the pipe elements. Ends of the band are in facing relation. Adjustable connection members are positioned at each end of the band for drawing the ends toward each other and deforming the band. Arcuate ribs are positioned lengthwise along opposite sides of the band. The ribs are separated from one another by gaps between the ribs. In their undeformed state, each rib has an arcuate surface with a radius of curvature equal to the radius of curvature of the outer surface of the pipe elements which they engage. When the band is deformed the ribs clamp against the outer surface of the pipe elements to effect the joint. | 11-06-2014 |

| 20100001515 | COUPLING MECHANISM - In a coupling mechanism, an inner peripheral wall of a coupling main body is inscribed with an outer side ring groove of containing an outer peripheral side edge portion of a stopper member, a stopper member introducing port formed by a width wider than a width dimension of a strip member of the stopper member is inscribed at a position of an outer wall portion of the coupling main body slightly shifted from a position of inscribing the outer side ring groove to a side of an inserting front end, the stopper member is applied with a spiral torsion such that both end portions opposed to each other of the strip member slightly carry out core deviation, an inner peripheral wall of the outer side ring groove is formed by a taper face in a state of being expanded from a rear end side to a front end side in an inserting direction, also an outer peripheral wall of the stopper member is formed by a taper face of a shape in correspondence with the taper face of the outer side ring groove, the inner peripheral wall of the stopper member is formed by a shape substantially in parallel with an outer peripheral wall of the connected pipe, and a face of the inner peripheral wall is formed by a rough face achieving a slip preventing effect. | 01-07-2010 |
