This invention provides for a hand-held clamping tool to position and hold two pipe flanges in place allowing for the alignment the bolt holes and the gasket that in placed between the pipe flanges by using an alignment spike; and then holding the pipe flange and the gaskets in place while bolts are installed to join the two gasket sections together. The invention also has a detachable alignment spike and a also has a calibration mark on the alignment spike. The invention also describes a tool for positioning and holding ISO flanges.

A pipe joint includes first and second sleeves having fluid flow paths communicating with each other; an annular gasket interposed between abutting end surfaces of the sleeves; a male screw member having a through hole into which the first sleeve is inserted; and a female screw member having a through hole into which the second sleeve is inserted, the sleeves being joined by screwing the male screw member with the female screw member, wherein the pipe joint has a leak port opened at a portion of the outer peripheral surface of the male screw member not covered by the female screw member and communicates with a gap between the male screw member and the first sleeve to detect a leak fluid leaked from gaps between the sleeves and the gasket.

A compact strainer having a small pressure loss which is easily cleaned without inserting and detaching screens in and from a strainer casing. Front and rear end portions of a tubular casing are respectively provided with an inlet and an outlet. A barrier divides in two a linear channel between the inlet and the outlet along a flowing direction and is provided on the outlet side so as to face the inlet. A filter portion surrounding the inlet is constituted by the barrier, a pair of screens laterally opposing each other and arranged at a predetermined interval are provided, and the upper and lower portions of an inner surface of an outer wall of the casing, and upper and lower regions of the outer wall are provided with opening portions with lids which make the inside of the filter portion communicate with the outside.

A clamping system for connecting a first and a second tube whose opposite ends have clamping surfaces protruding from the cylindrical outer surface of the tubes. The system includes a collar having a belt able to be clamped around the clamping surfaces. The belt includes a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries an external retaining device having a retaining bar, which protrudes axially from the first flank while being oriented transversely to the axis of the collar and which has a transverse retaining ridge, the bar being able, from a rest situation in which the retaining ridge projects towards the axis of the collar relative to the edge of the first flank in the unclamped situation of the collar, to be elastically deformed to space the retaining ridge away from the axis of the collar.

A clamp includes a first clamp body portion arranged for removable coupling about a generally cylindrical support structure to a second clamp body portion. The first clamp body portion includes a first clamp structure containing a first generally semi-spherical floating bushing, the first generally semi-spherical floating bushing coupled to the first clamp structure. The second clamp body portion includes a second clamp structure containing a second generally semi-spherical floating bushing, the second generally semi-spherical floating bushing coupled to the second clamp structure.

A sealing interface includes a first tube having an end with a convex surface and a second tube having an end with a convex surface. A spacer is disposed between the respective ends of the first and second tubes. One side of the spacer has a concave surface that substantially matches the convex surface of the end of the first tube, and another side of the spacer has a concave surface that substantially matches the convex surface of the end of the second tube. The spacer includes a through hole in fluid communication with a fluid passageway of the first tube and a fluid passageway of the second tube. Tying elements are respectively coupled to the first tube and the second tube, with the tying elements applying a compressive force between the first tube and the spacer, and applying a compressive force between the second tube and the spacer.

A fluidic connection device (10) for a fluid circuit, in particular of a vehicle, this device comprising: a first pipe (12), a tubular end-piece engaged in the first pipe (12), a first flange (16) mounted around the first pipe (12), a second flange (18) mounted around the end-piece, at least one element (20) for attaching the first and second flanges (16, 18) one against the other, and a non-return insert valve (100) mounted within the first pipe (12).
