20110062706 | Seal Having Projections and Coupling Having Pockets - A ring-shaped seal has projections on an outwardly facing surface in the form of tubes which have a longitudinal axis oriented perpendicular to a plane containing the ring. The seal is received within a channel defined by segments attached end to end forming a coupling for coupling pipe elements in end to end relation. The segments have pockets which receive the projections. The projections support the segments in spaced apart relation to allow the pipe elements to be inserted into the coupling without loosening or disassembling it. The projections deform when the segments are drawn toward one another by adjustably tightenable fasteners and allow the segments to engage and capture the pipe elements in end to end relation. | 03-17-2011 |
20160061789 | PLUG UNIT AND CONNECTION SYSTEM FOR CONNECTING CAPILLARY TUBES, ESPECIALLY FOR HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY - A plug unit for connecting capillary tubes includes a plug housing that has an axial borehole, a plug capillary tube that projects through the axial borehole, and a sealing element that surrounds the plug capillary tube. The front end of the plug capillary tube is sealed by an elastic and/or plastic deformation of the sealing element against the capillary tube receptacle opening of a bushing unit. A hollow cylindrical pressure piece is provided that surrounds the sealing element in an axial region facing away from the end surface of the plug capillary tube, and the pressure piece has a rearward end side that faces away from the end surface of the plug capillary tube and that can be loaded by the plug housing with an axial pressure force when the plug unit and bushing unit are connected. | 03-03-2016 |

20090184517 | JOINING STRUCTURE OF TANK COMPONENTS - It is realized to prevent foreign matter from being produced due to abrasion or cutting of a bearing surface by improving abrasion resistance of the bearing surface. It is also realized to prevent the foreign matter from entering into a tank via the opening of a mouthpiece even when it is produced. The joining structure of tank components comprises a screw joining unit for joining with the mouthpiece of a high-pressure tank, a bearing surface axially contacting the mouthpiece on the tank component side, a bearing surface on the mouthpiece side, contacting the tank component side bearing surface, a recess provided on the inner peripheral side of a portion where the tank component side bearing surface contacts the mouthpiece side bearing surface with each other and on the outer peripheral side of an opening and forming a space between the tank component and the mouthpiece, and a seal member provided in the recess for preventing foreign matter intrusion into the opening in the mouthpiece. It is preferable to treat the surface of at least one of the tank component side bearing surface and the mouthpiece side bearing surface for abrasion resisting. | 07-23-2009 |

20150048615 | Seal Surface Configuration for Fluid System Components - A seal system includes a first connector member, a second connector member, a gland structure, and a seal member. The first and second connector members include respective seal structures. The second connector member is configured for connection to the first connector member. The gland structure is defined by the first connector member and the second connector member, and is located between the first and the second seal structures. The seal member is at least partially positioned in the gland structure. The first and second seal structures are configured to deform the seal member into the gland structure in response to connection of the first connector member and the second connector member. | 02-19-2015 |
20150369403 | FLUIDIC COUPLING SEAL - Described is a coupling seal that includes a polymeric body having a bore extending from a first end to an internal sealing surface and a fluid channel extending from the internal sealing surface to a second end. The bore is configured to receive a tube having a fluid channel so that an endface of the tube engages the internal sealing surface. The second end of the polymeric body is configured to contact a sealing surface of a coupling body that has a fluid channel extending from the sealing surface. A fluidic seal occurs when the coupling seal is compressed between the endface and the sealing surface. A void between an outer surface of the polymeric body and an inner surface of the coupling body receives the deformation of the coupling seal while under compression to thereby prevent the fluid channel of the tube from being crushed or obstructed. | 12-24-2015 |
