A connection system for fluid conduction having a male connection end (2), a female connection end (3) and a retaining element (4). The male connection end (2) having a retaining groove (21) which makes up a first recess (22). The female connection end (3) having a retaining hole (31) which makes up a second recess (32) facing the first recess (22). The retaining element (4) is designed to be inserted through the retaining hole (31) and be housed between the first recess (22) and the second recess (32) to keep the male connection end (2) attached to the female connection end (3) when both ends (2, 3) are connected. The connection system (1) has a gasket (5) placed between the male connection end (2) and the female connection end (3), configured to hinder relative movements of said ends (2, 3) when connected along an axial direction (X).

A pipe adapter including an inner tube member, a fastener member, an outer sleeve member, a compressible sleeve member, and a fitting member. The fastener member may have threads on an inner diameter adapted to matingly engage a threaded portion of the inner tube member along a proximal section thereof. The outer sleeve member may girdle the inner tube member and connect to and extend outwardly from the fastener member. The compressible sleeve member may be configured as at least one ring positioned to overlie the outer tube member. The fitting member may connect to a distal section of the inner tube member. At least a portion of at least one of the fitting member and the compressible sleeve member may be positionable within a portion of a pipe. The compressible sleeve member may extend outwardly from a longitudinal axis of the inner tube member toward the pipe.

An annular gasket intended to provide a tight assembly between a first and second pipe after crimping, including an axis of revolution, whereof a section parallel to said axis is a curve formed by a series of an odd number of circle segments C.sub.i connected by apices S.sub.i forming a regular polygon, i varying from 1 to 2*n+1, n being a positive integer greater than or equal to 1, the apex S.sub.i being the center of the circle passing through the apices S.sub.i+n and S.sub.i+n+1 modulo 2*n+1. Such a curve is said to have a constant width. The apices S.sub.i advantageously form a polygon.

A pipe gap assembly including an insert sleeve and an adjustment sleeve. The insert sleeve includes a first side large diameter section, a small diameter section and a second side large diameter section, with the insert sleeve having an insert sleeve enlarged lip at the second side thereof. The adjustment sleeve has a first side, a second side and a cylinder having an outer surface, with the outer surface of cylinder of the adjustment sleeve being smaller than an inner surface of the insert sleeve to allow the first end of the adjustment sleeve to be able to be slid within the insert sleeve. The adjustment sleeve further includes a ring seal surrounding the outer surface thereof. The ring seal is not fixed in position on the outer surface of the adjustment sleeve such that the ring seal is able to roll on the outer surface of the adjustment sleeve.

An O-ring gland fitting for a liquid cooling loop of an information processing device comprises a plug, a socket, and an O-ring. The plug comprises a mating protrusion and a plug gland surface. The socket comprises a socket gland surface and a mating recess configured to receive the mating protrusion in a mated state of the plug and socket. The plug gland surface and socket gland surface are configured to, in the mated state, form a gland which contains the O-ring. The plug gland surface comprises sealing surface features and the socket gland surface comprises complementary sealing surface features configured to, in the mated state, compress the O-ring therebetween and form multiple non-radial seal pairs. Each of the non-radial seal pairs comprises two contact-stress surface-seals formed by one of the sealing surface features and one of the complementary sealing surface features on opposite non-radial sides of the O-ring.
