A conduit clamping and sealing system includes: a bearing element including: a back segment with an external back thread for attaching to a device or fastening to a box or enclosure; a middle segment for receiving a conduit and guiding and/or aligning a hygienic sleeve system; and a front segment for receiving a seal, and a front nut for sealing a connection between the conduit and the bearing element and fastening the hygienic sleeve system.

A pipe coupling including an externally threaded body and an internally threaded nut. The nut's outer end includes an outwardly converging internal circular surface and a spacer is co-operable with the nut and body. The coupling further includes an O-ring and a deformable gripping member. The gripping member has an internal surface with barbs extending radially inwardly therefrom. An end of a pipe is insertable through said gripping member, spacer and O-ring into the body. Tightening of the nut causes axial movement of said spacer, sealing engagement of said O-ring to the body and pipe, and radially inward deformation of said gripping member such that said barbs clamp the pipe. The diameter of the O-ring is greater than that of the spacer at points where it is secured before tightening of the nut and less than that of the spacer when the nut has been tightened.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

A system for making a connection between a first tubular member and a second tubular member having coincident bores for conveying a fluid, the connection having an axis in the general direction of flow of said fluid therethrough, the system comprising a connection (1) and a tensioning tool (100), the connection having a first tubular end (6) comprising a first end flange (16) having an end face (17) and a collar (20) comprising a sleeve (21) and an end stop (30) fixed to the sleeve (21), said sleeve (21) arranged about said flange (18) and said end stop (30) arranged about said tubular end (6), said collar (20) slideable along said tubular end (6), the connection further having a second tubular end (7) comprising a second end flange (43) having an end face (45) and a locking nut (50) about and slideable along said first tubular end (7), the tensioning tool (100) for applying axial tension to said collar (30) relative to said second tubular end (7) characterised in that at least one of said sleeve (20) and said second tubular end (7) has a set of parallel circumferential grooves (23,47) therein and said tensioning tool (100) has a set of ridges (142), the system comprising the steps of moving said set of ridges (142) into said set of grooves (23,47) and applying an axial tension to said collar (20) relative to said second tubular end (7).

A conduit forming unit includes: a cylindrical tubular body having flanges, on both end portions of the cylindrical tubular body; a first connection tubular body and a second connection tubular body respectively connected to a first end portion and a second end portion of the cylindrical tubular body; and tube joints for connecting the cylindrical tubular body and the first connection tubular body and the second connection tubular body to each other. The tube joint includes: a pawl equipped nut where a plurality of pawl portions which are engageable with the flange of the cylindrical tubular body are formed in the pawl equipped nut, the pawl portions engage with the flange so as to connect the first connection tubular body and the cylindrical tubular body to each other; and a retaining ring being annularly mountable on the pawl equipped nut and retaining engagement of the pawl portions with the flange.

A universal coupling for hydraulic hose wherein the coupling has a male coupling which is constituted by a shank and a universal male part; and a female coupling having a universal nut compatible with the universal male coupling and wherein the universal nut has an internal universal thread and a turning up to the middle of the part in its external part which it is tightened to a piece having two ends or tips, where, the first tip has a turning and an external grooved element forming between them a box housing the nut and the second tip has a terminal head of standard and variable shape, where the terminal head joins the first tip through a segment.
